Explain why atoms are neutal.?

Atoms are neutral due to the balance between the number of \nelectrons and protons in the nucleus. In some cases, they are not balanced due to the absence one or more electrons in the orbit and they are called Ions.

Atoms want to be like a "noble gas" with a filled outer shell.  I think it has to do with being in a stable state.  For Mg, it's a lot easier to drop 2 electons to look like Ne rather than gain 6 to look like Argon.\n\nThis very basic premise only works for things on the "sides" of the table.  The transition elements in the middle are a bit different.

This has to do with electrons. Neon has a "full shell" of electrons, all of the inert gases do. Neon doesn’t want any electrons, and it doesn’t want to give them away. Oxygen wants "to look like" Neon. Oxygen has 6 electrons sitting in what is known as the outer shell, if oxygen gets to 8 like Neon it will be happy, to put it simply. This is also why Sodium is very reactive. Na will give away 1 electron so that it also looks like Neon. S wants to look like its counterpart Argon, Se wants to look like Kr. \n\nLooking at the periodic table is really useful when learning how elements behave.\n\n[edit] -the person below me just regurgitated something about protons and said my answer is invalid, and I'm a chemist so... Yes elements are defined by their number of protons, but these protons, being positive, attract electrons. Neon will attract 10 total electrons, the first two fill what is called the 1s orbital, next two fill the 2s, and the next six pair up into groups of two and fill the 3 lobes of the 2p orbital. Everything fills, no room for more electrons, no extra ones hanging out in too high of an orbital. Neon will not react because it will not take on more electrons and it will not lose them.

An atom has no charge because it likes to be stable and to be stable it has the same number of protons (positively charged particles)as it has electrons (negatively charged particles) therefore they cancel each other out of course sometimes they are not stable and are called ions which are charged atoms

True.  Elements are characterized by the nature of their atoms; each atom has a positively charged nucleus and is surrounded by a cloud of electrons.  All atoms of a particular element have the same nuclear charge.  Under normal circumstances, atoms are in a low energy state (the "ground state") in which the shape of the electron orbitals is roughly spherical -- bearing in mind that we're talking about the shape of a fog, without definite edges.  In higher energy states, the electron orbitals can get arbitrarily large.

How can you have something if nothings there? Atoms are made up or protons, neutrons, and quarks which are the basic building blocks of matter. Well at least until someone discovers there made up of something else lol!

Atoms are combinations of protons and neutrons with electrons flying around. They form the basic "elements" of matter.\n\nThe nucleus of an atom has protons and neutrons (except for hydrogen which has one proton). There are about the same number of protons and neutrons in each nucleus, although for larger nuclei (like uranium) there are more neutrons.\n\nAll of these particles have a variety of specific characteristics. For example an electron has a negative charge and a proton has a positive charge, while the neutron is neutral. The charge of the proton and electron are identical except for the sign.\n\nProtons and neutrons are both made of quarks. A proton has two "up" quarks and one "down" quark, while the neutron has two "down" quarks and one "up" quark. (The up and down are just names for these two types of quark, there is no physical significance to the name. They could have selected \nChocolate and Vanilla instead.)\n\nProtons and neutrons are almost always described as being composed of three quarks, but there are also gluons running around. Gluons are the particles which control the interaction of quarks within a proton or neutron. They carry the force that binds the three quarks together to form the larger particle.\n\nSo a proton or neutron has three quarks and a cloud of gluons.\n\n(Just as an aside: If one combines a proton and an electron and a neutrino you will get a neutron, but, in the oddness of quantum physics that doesn't mean a neutron is made of these little guys.)\n\nElectrons on the other hand seem to have no consituents, at least down to the level that has been probed with modern instruments.

This is because the nuclear attraction over the electrons increases.\nRemember Coulombs law of electro_nuclear forces.

b and d are not right.\n\nb. - going across a row the atoms get smaller so Co is smaller than Fe\nd  - Na is in row 3 and is larger than Be and Ne which are in row 2

Although atoms contain both positively and negatively charged particles, they contain the charges in equal portions. That is, an atom has the same number of electrons (negatively charged) and protons (positively charged), so the charges cancel each other out. \n\n\nHowever, an atom can gain or lose electrons resulting in a charged atom known as an ion.

Because being so dense, Uranium is higly unstable. A normal atom simply shouldn't contain that many protons, neutrons, and electrons, so every once in a while, protons start popping out, which is what causes the radiation output. Over time, Uranium gradually changes into lighter and lighter elements through the loss of its electrons. This process is called radioactive decay.\n\nBTW, I don't mean to show off, but I'm only 14.

the answer is a, the number of outer shell electrons it can gain or lose.\n\nthia is because that outer electrons are the ones the define the atom in terms of bonding. \nmass nubmer and atomic number dont matter much [as lower level chemistry] for bonds. we know that the number of molecules it can form is infinite, and inner shells dont matter, leaving us wiht (A), the only right answer

An atom is stable when it has a full valence (outer) electron shell.  For the first row on the periodic table, the outer (and only) shell can hold up to 2 electrons.  For the next two rows, the atoms' outer shells can hold up to 8 electrons.  The next two can hold up to 18.\n\nAtoms like sodium, in column 1 of the periodic table, have one electron in its valence shell.  It is very reactive, since it wants to get rid of this extra electron so that its outer shell can be full.\n\nAtoms like chlorine, in the second last column, have one electron missing from their valence shells.  They are also very reactive, since they want to accept an electron to fill the outer shell.\n\nNoble gases are almost totally unreactive, since they have the unique property of having full outer shells without having to give away or accept any electrons.

atoms of positive charge are lighter than negative.

atoms are in everything we see.  How the atoms are bonded determines how we see things such as color.  \n\nthey are not "alive" per say since they do not need to consume energy to exist.\n\nThey are electrical.  The forces that bind electrons to the nucleus are electrical bonds.  In fact, the binding energy for atoms to bond is also electrical.\n\nhope that helps

each type atoms have different no of proton that definize what atom is it.\ninteligent design. dont even thing about it\nlabs arround the world can make atoms from different atoms thru the process of nuclear fusion or fission. \n\nstability?? u mean in chemical compound, its because the atom bounding theory,  u will study it in chem\nif thats not what u r asking so I don no

what is the atom made of and explain how they work?
