plz help so confusing
an atom have [what] charge?

Atoms have equal number of protons and electrons thus canceling out the positive and negative charge respectively.
Ions are particles that has already given or lost their electrons to or from another atom so becoming charged particles called ions.

get this clear because if ur studying chemistry or physcis, you need to understand this.
atoms have NO charge.
Why, u ask?
u need to understand the role and protons and electrons in an atom to understand why atoms have NO charge.
PROTONS have a +1 charge. they are contained in the central part (nucleus) of the atom. their location however has nothing to do with this.
ELECTRONS have a -1 charge. they are orbiting the nucleus.
in an atom,
NUMBER OF PROTONS = NUMBER OF ELECTRONS
(always, always, always, always)
therefore, the number of +1 charges (of the protons) equals the number of -1 charges (of the electrons)
therefore, the two charges are opposite and equal and they cancel each other out.
therefore, atoms have NO charge.
however, when an atom loses an electron or gains an electron, it is known as an ION. in this case, the number of charges is not equal and they do not balance and cancel each out.
THEREFORE, AN ATOM HAS NO CHARGE
AN ION HAS A CHARGE
hope that clears ur doubts

atom don't have charges,since the overall no of protons(+ve) and electrons(-ve) are equal in the atom.if however a particular atom loses an electron it will become positvely charged because there's more protons then electrons in the atom which is now called an ion coz it has a charge.also i think its useful to now that protons don't move from atom to atom only electrons. so for example if that sodium electron is gained by a chlorine it becomes negatively charged because of the extra electron.

Atoms have no charge (are neutral) because their protons and electrons, which are equal but different in charge cancel each other out.
Ions have charges.

An atom is neutral as it contains equal number of proton and electron.

If it is an atom it has no charge, if it is an ion it can have many different charges

Usually goes like this...
Group IA - + charge
Group 2A- +2 charge
Group 3a - +3 charge, however, B doesn't usually have charge due to the fact it doesn't usually form monotomic ions with compounds
Group 4A- C/Si/Ge don't normally form compounds with monotomic ions so as their shouldn't be charges (usually) however, Sn and Pb have 2+ charges
Group 5A- N and Bi both have +2 charges, the rest are like the above
Group 6A - 2- charge
Group 7A- - charge

An atom on a whole is neutral as it has equal no of protons and electrons.

zero charge, unless they have gained or lost their normal electrons.
