Question

For the symbol H.D and T tabulate three sub - atomic particles found in each of them.

Answer 1

Hi..I have 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 n

Deuterium(D)= Number of protons= 1 p⁺

                     = Number of electrons= 1 e⁻

                     = Number of neutrons= 1 n

Tritium(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!!

Answer 2

Answer:

H, D, and T are the three isotopes of hydrogen with the same atomic number and different mass numbers of 1, 2 and 3 respectively.

Element Symbol Number of Electrons Number of Protons Number of Neutrons

Hydrogen H 1 1 0

Deuterium D 1 1 1

Tritium T 1 1
