If an atom has 14 protons, 11 neutrons, and 15 electrons, what is the atom's electrical charge?

-1 because each electron holds a charge of -1 and each proton has a charge of +1 and the neutrons have no charge.

Ithink it’s one of those things that you put the object on

☆ionisation energy increases across a period from na -> ar☆ionisation energy decreases down a group from li -> fr☆ionic radius decreases across a period from na -> cl☆ionic radius increases down a groupfrom f -> ii hope it clarifies your doubts
