Question

For the symbol H, D and T tabulate three sub-atomic particles found in each of them. plz explain me this question and tell the answer also

Answer 1

Here, H,D,and T means three isotopes of hydrogen element.
Now, you should know that what is an isotope?
Isotopes are atoms of same element having the same atomic number but different mass number.
H stands for Hydrogen or protium.It has only one proton and one electron but no neutron.
D stands for duetrium. It has one proton, one electron and one neutron.
T stands for tritium. It has one proton, one electron and two neutrons.
Here, in all these three you can observe that the no. of protons and electrons i.e the atomic number is same but the atomic mass or mass number is different.Therefore, all three are isotopes of hydrogen element.
Hope it had cleared your confusion.
