D. Protons and neutrons have the same charge.

Answer 1

D is not true :D

Answer 2

Neutrons have no charge at all.

Protons have \[+1.6 \times 10^{-19}C\]charge

Electrons have \[-1.6 \times 10^{-19}C\]charge

Answer 3

Protons have mass equal to \[1.67 \times 10^{-27}kg.\]Electrons have mass equal to\[9.1 \times 10^{-31}kg.\]

Answer 4

one more thing

Neutrons have mass equal to \[1.6 \times 10^{-27}kg.\]Same as proton.

Answer 5

These must be remembered
these are very useful:D
