Question

Name the light element having 3 isotopes ?

Answer 1

Answer:

$\huge \underline{ \rm \red{hello}}$

Hydrogen is the light element.

• The three most stable isotopes of hydrogen: protium (A = 1), deuterium (A = 2), and tritium (A = 3).

• Protium, the most common isotope of hydrogen, consists of one proton and one electron.

• A deuterium atom contains one proton, one neutron, and one electron.

Composed of a single proton and a single electron, hydrogen is the simplest and most abundant element in the universe. ... Liquid hydrogen is used in the study of superconductors and, when combined with liquid oxygen, makes an excellent rocket fuel. Hydrogen combines with other elements to form numerous compounds.

H (atomic mass 3.01604928199(23) u) is known as tritium and contains one proton and two neutrons in its nucleus. It is radioactive, decaying into helium-3 through β− decay with a half-life of 12.32 years. Trace amounts of tritium occur naturally because of the interaction of cosmic rays with atmospheric gases.
