Just 5 and 10 only answer the question

5] Neutron: Charge= 0 Atomic mass unit = 1

10] Hydrogen:

Number of protons = 1

Number of neutrons = 0

Number of electrons = 1

Atomic number = 1

Helium:

Number of protons = 2

Number of neutrons = 2

Number of electrons = 2

Atomic number = 2

Note:

Atomic number = proton number

Neutron number = Mass number - atomic number

Number of electrons = number of protons
