Explanation:
Answer:
5] Neutron: Charge= 0 Atomic mass unit = 1
10] <u>Hydrogen:</u>
Number of protons = 1
Number of neutrons = 0
Number of electrons = 1
Atomic number = 1
<u>Helium:</u>
Number of protons = 2
Number of neutrons = 2
Number of electrons = 2
Atomic number = 2
<em>Note:</em>
<em>Atomic number = proton number</em>
<em>Neutron number = Mass number - atomic number</em>
<em>Number of electrons = number of protons</em>
