Question

What are the three isotopes of hydrogen and what is the significance of these isotopes?

Answer 1

Answer:

21H deuterium (D), 31H is tritium (T), 11H is hydrogen

Explanation:

11H: it has the greatest abundance, it has only one proton (it does not have neutrons).

 21H (D): it has a proton and a neutron in its nucleus.

 31H (T): it has a proton and two neutrons in its nucleus.

Remember that isotopes have the same atomic number, but a different mass number (elements in the number of neutrons differed).

Answer 2

Answer:

See below.

Explanation:

They are Hydrogen 1 , Hydrogen 2 (also called deuterium) and Hydrogen 3 (tritium)

Hydrogen has no neutrons in the nucleus while deuterium has 1 and tritium has 2.

Deuterium has been used in the nuclear industry ( as heavy water , deuterium oxide) and  as a compound lithium deuteride in the H bomb. Tritium  is also used as a fuel in nuclear fusion reactions,  and as a radioactive tracer.
