Question

An atom has an 16 protons, 18 neutrons, and 13 electrons. What are its atomic number, atomic mass, and net charge?

A) atomic number = 16, atomic mass = 34, net charge = 3+
B) atomic number = 16, atomic mass = 34, net charge = 3−
C) atomic number = 34, atomic mass = 16, net charge = 3+
D) atomic number = 34, atomic mass = 16, net charge = 3−

Answer 1

Atomic number = number of proton = 16

Atomic mass = number of proton + number of neutron = 16+18 = 34

Net charge = Number of proton - number of electron = 16-13 = +3
