Question

An ion that consists of 7 proton,7 neutrons and 10 electrons has a net charge of ?

A 3+
B 4+
C 4-
D 3-​

Answer 1

C. 3-

Step-by-step explanation:

Protons have an individual charge of 1+, neutrons have no individual charge, and electrons have an individual charge of 1-.

So the total charge from protons is 7+ and electrons 10-, which gives a net charge of 3-.
