Answer:

Hope it helps u

Explanation:

FOLLOW MY ACCOUNT PLS PLS

Questions about the kind of charge, the magnitude of charge etc can be asked when the charge on an ion is determined.

An ion is a charged atom or a charged molecule. It attains a charged state because the number of electrons does not remain equal to the number of protons in the atom or the molecule.

The gain of a positive charge by an atom or a negative charge will depend on the fact that whether the number of electrons in an atom is greater than the number of protons or less than the number of protons.

If the atom loses electrons, the total proton number will be higher, so the atom will become positive. If the atom gains electrons, the total electron number will be higher, so the atom will be negative.

The attraction of an atom to another atom happens because it has an unequal number of electrons and protons, then the atom is called an ION. If the atom has more electrons than protons, it is a negative ion or ANION. If it has more protons than electrons, it is a positive ion.
