Question

what is an

electron?
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:

An electron is a subatomic particle. Protons have a positive charge, neutrons have no charge. The nucleus consists of protons and neutrons. The total number of protons and neutrons in the nucleus is the mass number. Electrons are subatomic particles with a negative charge.

Answer:

a subatomic particle whose electric charge is negative
