Question

An element that has 10 protons, 9 electrons, and 11 neutrons. What is the net/ionic charge of this atom?

A) -2

B) -1

C) +1

D) +2

Answer 1

Answer: (C) +1

Explanation:

Neutrons have no charge, so we can ignore them in this problem. Protons have a 1+ charge, and electrons have a 1- charge. So, the total charge is 10(+1) + 9(-1) = +1.
