question 1 What makes up an atom? (Choose all that apply)

a
protons
b
particles
c
compounds
d
neutrons
e
electrons
question 2
The number of protons in an atom represent the

a
atomic number
b
atomic structure
c
mass number
d
mass structure
question 3
The process of negatively charged electrons pulling toward positively charged protons is known as

a
gravity
b
electromagnetic activity
c
electric force
question 4
Strong force occurs because neutrons work to keep protons in place inside the nucleus of an atom so the protons do not push each other out of the atom.

True
False
