A proton carries a charge of +1 and a neutron does not carry a
charge.
TRUE
FALSE

True    

Explanation:

it is

True

Yes the unit at which charge is mesured means a proton has +1 charge and neutron has no charge

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

c is the answer because when something is left after something evaporates that shows the chemical change.
