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 is always equal to the number of the proton so 16
atomic mass is the sum of protons and neutrons so 34
There are 3 less electrons when compared to the protons so 3+

Answer 2

i think this answer can be C.
