Question 3
3.
Select all which are true
Electrons
: Have a negative charge
Question 4
4.
What is the difference between an
atom
and an
Ion
?
There is not difference between atoms and ions
Ions are neutral, but atoms have a charge.
Atoms have all three subatomic particles, but ions only have electrons
Atoms are neutral and ions have a charge
Question 5

Indicate which descriptions are true for atoms and ions.
Protons = Electrons
Lose or gain electrons
Have a charge
Are neutral
Atoms
Ions
