For the symbols H, D and T,tabulate three sub-atomic particles found in each of them.
H,D and T are the three isotopes of hydrogen having the same atomic number 1 but different mass numbers of 1, 2 and 3 respectively. The symbol H stands for ordinary Hydrogen (of mass number 1), the symbol D stands for Deuterium (which is heavy hydrogen of mass number 2) and symbol T stands for Tritium (which is very heavy hydrogen of mass number 3). The three sub-atomic particles, electrons, protons and neutrons,in the three isotopes of hydrogen are given in the following table :
| Isotope | Symbol | Mass number | Number of electrons | Number of protons | Number of neutrons |
