What is trick to learn charge of an atom

Answer 1

hi mate here is your answer....


An ion is an atom that has gained or lost one or more electrons and therefore has a negative or positive charge. A cation is an atom that has lost a valence electron and therefore has more positive protons than negative electrons, so it is positively charged.

Subtract the number of electrons from the number of protons in an atom as a basic way of calculating the charge of the ion. For example, if a sodium atom loses one electron, work out 11 - 10 = 1.
