the nucleus of an atom usually contains ___.
protons
neutrons
protons and neutrons
neither protons nor neutrons

Explanation:

First Question (Relative electrical charge of a proton)

Protons have a positive relative electrical charge. By definition in atomic structure (Physics/Chemistry), the relative charge of a proton is +1. Electrons have -1, neutrons have 0.

The atomic nucleus is composed of protons (positively charged) and neutrons (neutral). Electrons are outside the nucleus. So the nucleus usually contains protons and neutrons.

Answer:

B. +1
