Question

Hydrogen has 3 isotopes .State the composition of their nuclei and write their mass no. Also represent them in the form of symbol.

Answer 1

Hydrogen has 3 isotopes.

1)Protium (2) Deuterium (3)Tritium

●Protium: It has one proton and one electron.I t doesn't have any neutron.So its mass no is 1.Its symbol is 1H1


● Deuterium : It has one neutron one electron and one proton.So it's mass number is 2.Its symbol is 1H2


● Tritium: It has two neutrons one electron and one proton.So it's mass number is 3.Its symbol is 1H3



Hope it helps

Answer 2

isotope- mass no -no of proton -no of neutron
protium- 1-1-0
deuterium- 2-1- 1
tritium- 3 -1-2
hope its help you
