We, along with everything else in the world, are made up of atoms. Atoms are the basic building block of all matter.  The periodic table lists the different "elements" in the universe. Each element is made of a unique kind of atom, and there are no other kinds. For example, you can have oxygen atoms, or carbon atoms, but there are no plastic atoms. Anything more complex than the elements is made by sticking atoms together to form molecules - you *can* have a plastic molecule.\n\nAtoms consist of a nucleus, which contains protons (positively charged particles) and neutrons (no electrical charge.) The protons and neutrons are the heavy part of an atom. Electrons (negatively charged particles) orbit around the nucleus. \n\nThere are always the same number of protons and electrons, so the positive and negative charge cancel each other out. The number of neutrons can vary. Adding the number of protons and neutrons will give you the "atomic mass" of an element.

Atoms consist of protons and neutrons in a nucleus, with electrons in shells round it. \nIn an uncharged/neutral atom, the number of protons and electrons are equal and this is the same as the atomic number. In the periodic table, the elements are arranged in order of increasing atomic number. \nA molecule is two or more atoms chemically bonded together.\ne.g. Ne is an atom and H20 is a molecule.

Don't know who told you that "atoms only consist of energy", but in general, that's nonsense. Atoms consist of electrons and the nucleus (protons and neutrons, which again are made up from quarks), and these particles have a well defined rest mass. Einsteins theory of relativity is well proved and gives us the famous equation E=mc^2 for the energy equivalence of a rest mass, *which does not mean that energy and mass are the same*. It just means that you can transform energy and mass into each other and are equivalent in a certain (relativistic) way.\n\nSo if you want to make a fool out of yourself: Go ahead and try to disproof Einstein, like thousands of fools have tried before. If you're really interested in physics, go and get some good books about the basics, and you're welcome to come back with some more serious questions.

Atoms are the smallest pieces of an element that still exhibit that element's properties.  They consists of a nucleus (protons and neutrons) and  electrons.  A hydrogen atom doesn't even have a neutron.\nA molecule is a combination of atoms of at least two different elements.  These atoms share at least one electron through a covalent bond.  The molecule will exhibit some of the properties of each of its ingredient elements, as well as some of its own unique properties.\nA neutral atom or group of atoms has no charge. It is neither a positive nor negative ion.\nAn ion is an atom or group of atoms that has either more or less electrons than it has protons.  If its number of electrons is greater that its number of protons, then it has a negative ionic charge, in the amount of the difference.  If its number of protons is greater than its number of electrons, then it has a positive ionic charge, in the amount of the difference.

All matter is made up of atoms. God put atoms together to make everything.

Superb question because it gets into the basis of meaning.\n\nIn describing atoms, we use different "models".\n\nNo one model is always right or always wrong.\n\nSome models are useful for some tasks, others work better in different situations.\n\nThe atom is the classic example of the "Blind Men and the Elephant" -- the guy holding the tale thinks an elephant is a piece of rope, trunk guy thinks it is a snake, side guy thinks it is a wall etc.\n\nThe atom just IS. Depending on how we observe it, we can use different simulations, ideas or models to work with it.\n\nBest wishes and thanks for the cool question!

Atom  \n\nThe smallest unit matter can be divided into whilst still retaining its chemical identity. Atoms are not single particles but complex arrangements of three types of particles. The subatomic particles, protons, neutrons and electrons, combine to form atoms. The protons and neutrons provide the bulk of an atom's mass and are concentrated into a tiny central region known as the atomic nucleus. The nucleus is held together by the strong nuclear force which acts between the constituent particles (termed nucleons ). The protons are positively charged and so mutually repel each other, but it is not until there are many of them that they overcome the nuclear force. Thus there is only one stable element beyond lead (Z=82). Whilst the radius of an atom is in the region of 10-10 metres, the atomic nucleus is about ten thousand times smaller at 10-14 metres. The volume surrounding the nucleus is where the electrons exist. They are much lighter than the protons and neutrons and carry a negative electrical charge. Being opposite in charge to the nucleus, the electrons are held in orbits around it by the force of electromagnetism. The electrons exist in electron orbitals around the nucleus. These orbitals are grouped into shells. Within each shell are energy levels which allow the electrons to exist in unique quantum states, depending upon their angular momentum (hence energy), in accordance with Pauli's exclusion principle . In a neutral atom the number of electrons equals the number of protons. When ionisation occurs, one or more electrons are provided with enough energy to escape the atom altogether. What remains is known as an ion because it is now positively charged and will behave in a different way chemically from neutral atom. The number of protons in the nucleus of an atom (the atomic number , Z) defines which chemical element it is. There are just over 110 known chemical elements and these can be arranged in a classification sequence known as the periodic table. The number of neutrons in any given atomic nucleus can also vary. The total number of protons + neutrons is termed the atomic mass number (A). Most atoms have a prefered number of neutrons at which their nuclei are stable. Atoms with more or less neutrons than the stable configuration are known as isotopes and will often undergo radioactive decay. The simplest of all atoms is hydrogen and is a special case which has a nucleus of one solitary proton and a single electron in orbit around it. It is the only nuclide (species of nucleus) with no neutron. A stable isotope of hydrogen is called deuterium which has one neutron in its nucleus; tritium is an unstable (radioactive) isotope of hydrogen and has two neutrons.

Hm.  Okay.  Here's some stuff about atoms to get you started:\n\nJust like all things are made of atoms, all atoms for the most part are made up of the same three parts.  Protons, neutrons, and electrons.\n\nProtons and neutrons are comparatively really heavy.  Pretty much all the weight of an atom comes from these guys.  Because they're heavy, they don't move around a lot unless the whole atom is moving.  Instead they stick together in the center of the atom (also called the nucleus).\n\nElectrons live very different lives.  Unlike protons and neutrons, they are not only light but comparatively large.  They buzz around the nucleus like planets around a star... or perhaps more like beach balls around a sack of marbles.  A lot of chemistry has to do with electrons zipping around, being attracted to one thing or another... or more likely to several things at once.\n\nAnother important thing to know about the parts of atoms is their charge.  The charge in these parts come from the electric force, which (if you can imagine it) is a billion billion billion billion billion billion times stronger than gravity (yes, that's a one followed by 36 zeroes).  The electric force is also involved with electricity that we use in our houses and the like.\n\nThe pro- in proton comes from its positive charge.  To make things easy for themselves scientists just decided to say a proton has a +1 charge.  The neu- in neutron comes from it being neutral.  It has zero charge.  Electrons have the opposite charge of protons, so they have a -1 charge.  Pretty straightforward.\n\nAnd here's where things get interesting.  The name we give an atom (like helium or uranium or whatever) depends ONLY on the number of protons it has.  So, for example, an atom with two protons is helium, no matter WHAT else its got.  Neutrons hang out in the nucleus with protons, where they add to the weight of an atom but don't do much else.  And the REASON all those electrons are buzzing around a boring nucleus instead of being off somewhere else is because all those negative charges like to be near all those positive charges.  And since the electric force is so incredibly strong, you can bet that just about everything you run into is going to have as close to a zero total charge as it can get.\n\nSo there you have it.  Atoms in a nutshell.  Hope that helps!

An element, sometimes called a chemical element, is a substance that cannot be divided or changed into other chemical substances by any ordinary chemical technique.\n\nElements outside of nature are those that have been created by smashing molecules together in labrotories.  They generally have a very short halflife.\n\nElements occuring in nature can be found on the periodic table and go from Hydrogen (1) to Uranium (92).\n\nSome ancient philosophies used a set of classical elements to explain patterns in nature.  These were Air, Fire, Water, Earth and Aether.  These were used throughout the middle ages to help people explain things that weren't fully understood like how some objects floated, why people got sick, etc.\n\nIn popular western media these elements were revitalized and include Air, Earth, Fire, Water and sometimes Spirit.\n\nThey are also now used in some neo-pagan religious practices. \n\nRegards,\nArmus

Use the periodic table of the elements.  The "weights" are in grams per mol.  Just use algebra and solve for the number of mols.  Then you know how many atoms there are by the number of mols which is a definite number.

Well, both your teachers are right. :)\n\nAtoms make molecules make cells make tissues make human body.\n\nOther information that you need to know:\n\nA cell is a complex molecule, depending on the type of cell (Eukaryote or Prokaryote; human cells fall in the former category) and humans are complex organisms, therefore their, or, should I say, OUR cells consist of more complex materials than Prokaryotic cells (e.g. of Prokaryotic cells-  Bacteria) In any case, cells contain this thing called the nucleus, and the nucleus is like a 'house' for your genetic material. These genetic material- yes, your DNA, is made up stuff called amino acids, proteins and a sugar called ribose. As you know sugar contains Carbon, Hydrogen and Oxygen. Recognize those? Yes- those are atoms :) And your amino acids are made up of Carbon, Hydrogen, Phosphorus and Nitrogen.\n\nSo to be really technical about it, your body is made up of atoms which then make up cells. It is not wrong to say that in biology, cells make up the basic foundation of the body since Biology looks into the cellular level of the aforementioned subject, and not always at the atomic level.\n\nI hope this answered your question! :)

Element talks about the chemical identity.  How one atom is not like another.\nAtom talks about the particular entities.\n\nElement is a general term while atom is a specific term.\nSo you can speack of the element so and so and be describing the substance and its properties for example as that element is in all the universe.
