Basic Atomic Structure\n\nThe definitions of atoms and elements seems, at first glance, almost circular: an element is a substance made up of only one kind of atom, and an atom is the smallest particle of an element that retains all the chemical and physical properties of the element. In fact, these two definitions do not form a closed loop, as they would if it were stated that an element is something made up of atoms. Every item of matter that exists, except for the subatomic particles discussed in this essay, is made up of atoms. An element, on the other hand, is—as stated in its definition—made up of only one kind of atom. "Kind of atom" in this context refers to the number of protons in its nucleus.\n\nProtons are one of three basic subatomic particles, the other two being electrons and neutrons. As we shall see, there appear to be particles even smaller than these, but before approaching these "sub-subatomic" particles, it is necessary to address the three most significant components of an atom. These are distinguished from one another in terms of electric charge: protons are positively charged, electrons are negative in charge, and neutrons have no electrical charge. As with the north and south poles of magnets, positive and negative charges attract one another, whereas like charges repel. Atoms have no net charge, meaning that the protons and electrons cancel out one another.

The electron of a hydrogen atom orbits around the hydrogen atom nucleus. If there was no electron it wouldn't be an atom of any kind. In other words, the electron is "inside" a hydrogen atom.\n\nThis website for graphics of the hydrogen atom and suggestions for a science project:\n\nhttp://education.jlab.org/qa/atom_model.html

Protons and neutrons.

A neutral atom is redundant. The atom is neutral by nature. When the atom gets a positive charge then becomes a cation and when it gets a negative charge, becomes an anion.\nin the atom, the positive charges (protons) and the negative charges (electrons) are balanced.

actually, it's arranged by the number of protons in the nucleus of an atom of each element, though the list in this song: http://www.privatehand.com/flash/elements.html\nis not.

Molecules came from atoms combining. Atoms came from protons, neutrons, and electrons combining. Protons and neutrons came from quarks combining. Quarks and electrons came from condensation from the high energy vacuum. Where that came is still a bit up in the air, but look at the website below:\n\nhttp://www.sciencedaily.com/releases/2006/05/060515232747.htm

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.

It looks like a stable atom. The protons, neutrons, and electrons are all equal so they do not need to take away from other atoms. The maxium number of protons, neutrons, and electrons vary for each element. For example some elements on the periodic table can only contain 8 protons on the outer shell. Etc. And this question would get better answer if it was in Physics or Chemistry.

Obviously, an atom isn't the smallest particle since they are composed of sub-atomic particles.  An atom however is the smallest component of an element having the chemical properties of the element.  Once you go beyond an atom of any element, the components no longer keep the properties of that element.

number of atoms (of each element) on one side equals the other side.

Electron is simply the smallest and ligthest subatomic particle inside every atoms. as you know, atom consists of protons (positively charged), neutrons (no charge) and electrons (negatively charged). you can imagine atoms to be like a planet which has meteors orbiting around it. the planet represent the nucleus which consists of the protons and the neutrons. and the meteors around are representing the electrons. due to its light weight, electrons move around in an incredible speed around the nucleus. however, electrons do not escaped from the nucleus because they are bounded by forces which keep them in tracks. you can check it out in www.wikipedia.com if you need more info on electrons :D .

An atom is the smallest unit of any observable thing you can have. Atoms make up almost everything we can see.\n\nIt's name is Greek for 'Indivisable' but we have since found that atoms are made of protons, neutrons and electrons (and the first two are made of even smaller particles).\n\nAn element is a substance that is entirely comprised by only one type of atom. Gold, Tin and Oxygen are elements because they are made entirely of Gold, Tin and Oxygen atoms.\n\nMolecules and Compounds are similar in that they are made up of two or more atoms of different elements in a precise and defined ratio. Atoms in compounds can be ionically bonded. Molecules are, generally, covalently bonded.

The number of atoms/ions of an element on either side of the equation.\nThe total charge on either side of the equation.\nThe elements present are the same on either side of the equation.

The atomic number of an element is equal to the number of electrons it has. Do you mean something more than that?

Atoms do not have a charge.\nIons have a charge (either plus or minus)

Every atom has two unique numbers: Atomic Number (Z) and mass number (A). Atomic number Z represents the number of protons in the nucleus of an atom. Mass number A represents the number of neutrons and protons in the nucleus of an atom. When atoms are expressed on a periodic table, they are written with a number on the top and a number on the bottom. Z is written on the top and A is written on the bottom. Also when elements are represented with the name and a number on the upper lefthand side corner. This number represents the electrical charge of the atom. This is the number that tells us if the atom gained or gave away electrons.\n\nTo calculate the number of protons: Simply just look at the atomic number and it is the number of protons. For example Number of protons in a sodium atom is 11.(Z=11)\n\nTo calculate the number of electrons: Subtract electrical charge of the atom from the atomic number. For example Na+1 tells us that sodium atom gave an electron away. So 11-1=10 electrons present.\n\nBut the number of electrons is equal to the number of protons when the atom is not charged.\n\nTo calculate the number of neutrons: Subtract the atomic number from the mass number. For example, to find the number of neutrons in the nucleus of a sodium atom 23-11=12 neutrons.
