Respuesta :
the loss of one or more electrons & the addition of one of more electrons
Explanation:
Loss of one or more electrons by a neutral atom will help the neutral atom to acquire a positive charge.
For example, atomic number of sodium is 11 and to stabilize itself it needs to lose one electron. So, by losing an electron it will change into [tex]Na^{+}[/tex] ion.
On the other hand, gain of one or more electrons by a neutral atom will help the neutral atom to acquire a negative charge.
For example, Cl has atomic number 17 and to fill its octet completely it need one more electron. So, by gaining an electron is will change into [tex]Cl^{-}[/tex] ion.
Therefore, we can conclude that an ion is an atom with a net electrical charge due to loss or gain of electrons.
