Question

Name the Isotopes of hydrogen with their symbols.​

Answer 1

Explanation:

Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. The isotopes of hydrogen have, respectively, mass numbers of one, two, and three. Their nuclear symbols are therefore 1H, 2H, and 3H. The atoms of these isotopes have one electron to balance the charge of the one proton.

$\Large{\green{\tt{\underline{\underline{Isotopes \ }}}}}$

Isotopes can be defined as the variants of chemical elements that possess the same number of protons and electrons, but a different number of neutrons. In other words, isotopes are variants of elements that differ in their nucleon numbers due to a difference in the total number of neutrons in their respective nuclei.

$\Large{\purple{\tt{\underline{\underline{Isotopes \ of \ Hydrogen}}}}}$

There are three isotopes of hydrogen namely, protium 1H1, deuterium 1H2 or D and lastly tritium 1H3 or T. The isotopes are different because of the different number of neutrons present in them.

In protium, there is no presence of neutrons, whereas in deuterium we have one neutron and in tritium, we have two neutrons.

Out of these three isotopes of hydrogen, the only tritium is radioactive in nature which emits low energy b particles.
