An Ion of the Isotope Chlorine-35 Has an Ionic Charge

An ion of the isotope chlorine-35 has an ionic charge of 1-. How many protons, neutrons, and electrons does it contain? (p = proton, n = neutron, e = electron) Hint: Consider how changes in the number of electrons versus the number of protons affects the ionic charge of an ion.

A) 17 p, 35 n, 17 e
B) 17 p, 17 n, 35 e
C) 18 p, 17 n, 18 e
D) 17 p, 18 n, 18 e
E) 35 p, 17 n, 18 e
