Question

An element with 10 protons, 12 electrons, and 13 neutrons is has a charge of

Answer 1

. The number of neutrons is a distractor. Only the number of electrons versus the number of protons determines ionic charge. The charge of the ion is 2+ .

Answer 2

Explanation:

An atom of an element is electrically neutral when-

No. of protons = No. of electrons

But here the no. of electrons (12) is greater than the no. of protons (10), i.e.,

No. of electrons > No. of protons

So,we can tell that the atom of the element is negatively charged.
