Question

what is a neutron? * 20 points
the small dense region
consisting of protons
and neutrons at the
center of an atom
a stable subatomic
particle with a positive
electric charge
the total number of
protons and neutrons in
the nucleus of an atom
a subatomic particle
that has no electric
charge
a subatomic particle
whose electric charge is
negative

Explanation:

A neutron is a subatomic particle. It is located in the nucleus of an atom along with protons. Unlike protons (which have a positive charge) and electrons (which have a negative charge), neutrons have no electric charge.

• The first option describes the nucleus, not a neutron.
• The second option describes a proton (positive charge).
• The third option describes the mass number (sum of protons and neutrons), not a neutron.
• The fifth option describes an electron (negative charge).

Answer:

a subatomic particle that has no electric charge
