If an atom has 16 protons, 14 neutrons, and 18 electrons. What is the charge of the nucleus?

. The atom has 2 more electrons than protons giving it a negative charge (2-)

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
