Given information

Given statements :

a. If an atom has an equal number of protons and electrons, it is charge-neutral.

b. Electrons are attracted to protons.

c. Electrons are much lighter than neutrons.

d. Protons have twice the mass of neutrons.

Step-by-step explanation

Step 1.

The atoms are made up of subatomic particles. The subatomic particles that constitute the atom are electrons, protons, and neutrons.

On checking each statement :

a. If an atom has an equal number of protons and electrons, it is charge-neutral.

 Reason:

The charge of a proton is  and  the charge of an electron . Since the magnitude of the charge is the same but the sign is opposite, so the equal number of protons and electrons neutralize each other's charge.

Hence statement "a. If an atom has an equal number of protons and electrons, it is charge-neutral." is True.
