Answer»

ave had the same NCERT textbook, Structure of the Atom, isn't it?Hydrogen(H)= Number of protons= 1 p⁺                     = Number of electrons= 1 e⁻                     = Number of NEUTRONS= 0 nDeuterium(D)= Number of protons= 1 p⁺                      = Number of electrons= 1 e⁻                      = Number of neutrons= 1 nTritium(T)=  Number of protons= 1 p⁺                = Number of electrons= 1 e⁻                = Number of neutrons= 2 n Deuterium and TRITIUM are isotopes of Hydrogen with the ATOMIC number 1 and MASS numbers 2 and 3 respectively.Mark it as the brainliest!!:)
