The following best describes a neutron:  c. It is found in the nucleus.

Further explanation

An atom is the smallest material consisting of a nucleus, which contains protons, neutrons, and electrons that surround it  

Protons are positively charged (+1), electrons are negatively charged (-1). and neutrons are uncharged (neutral)

The Atomic Number (Z) indicates the number of protons in an atom of an element.  

The mass of each basic particle :

  • electron mass = 9.11.10⁻²⁸ grams  
  • proton mass = 1.6726.10⁻²⁴ grams  
  • neutron mass = 1,675.10⁻²⁴ grams  

Atomic number = number of protons = number of electrons  

Mass Number (A) is the sum of protons and neutrons  

Mass Number (A) = Number of protons Number of Neutrons  

Let's look at the answer choices :

  •  a. It has a negative charge.

neutrons have a neutral charge

  • b. Its mass is much greater than the proton.

neutron mass = 1,675.10⁻²⁴ grams and proton mass = 1.6726.10⁻²⁴ grams , so the masses of the two are almost the same

  • c. It is found in the nucleus.

electrons circulate around the nucleus, proton+neutron in the nucleus

d. the number of neutrons is called the mass number.

Mass Number is the sum of protons and neutrons
