Do all atoms have a positive and negative charge?

Answer 1

Yes and no. the nucleus has protons and neutrons so it has a neutral charge and a positive charge.

Further answer

But in total the resultant charge is positive, which is what the questioner wants to know.
Yes the nucleus of an atom carries a positive charge.

Answer 2

Short answer: All atoms have a neutral charge, positive charge, or negative charge.

More detail:

Every atom, when 'in balance', has a neutral charge. This means the number of electrons around the nucleus is equal to the number of protons in the nucleus. The charges cancel out, thus giving the atom a neutral charge. Neutrons have a neutral charge, so even if they are in the nucleus, it will not affect the charge.

If the particle has a positive or negative charge, it is referred to as an ion. If electrons are taken away, it becomes a cation, or a positively charged atom. If the atom gains electrons, there are more 'negatives' than positives, so the atom becomes an anion, or negatively charged ion. Anions and cations sometimes are attracted to each other due their charges, so they tend to combine to make an ionic compound, such as sodium chloride (NaCl), also known as salt. They then retain their positive and negative charges, and are stuck together by the attraction of those opposite charges.

For some reason, atoms tend to 'want' a full valence shell- that is, they 'want' their outermost layer of electrons to be filled up. Elements in period 7 tend to 'want' to gain 1 electron to become 'noble', as they are 1 column away from it. Noble gases (elements in period 8) are neutrally charged and have full valence shells, or they do not 'want' to gain or lose electrons. Elements in the first period tend to 'want' to lose the extra electrons and gain a positive charge.

Answer 3

No, they are not.

All atomic nuclei are positively charged.

Depending on how pedantic you wanted to be, you could say that no atoms are charged at all (those charged things that look like atoms are ions, and they can be either positively or negatively charged.).

Answer 4

Atoms have positive charges in their necleus named protons.This is equal to the number of electrons revolving around them. So the atom is neutral.

Answer 5

All atoms are neutral, which is to say, uncharged. They can become either positively or negatively charged, which makes them ions.

Answer 6

No, atoms are neutral; they carry not net charge.

Answer 7

no and yes... some are negative and some are positive

Answer 8

No, most atoms have no charge because there is an equal amount of protons and electrons but some atoms may have more protons or electrons depending on isotopes.
