Question

Explain all three isotopes of Hydrogen

don't spam ❎❎❎

Answer 1

Hydrogen (1H) has three naturally occurring isotopes, sometimes denoted 1H, 2H, and 3H. The first two of these are stable while 3H has a half-life of 12.32 years. ... The 2H (or hydrogen-2) isotope is usually called deuterium, while the 3H (or hydrogen-3) isotope is usually called tritium.

Answer 2

HELLO THERE!
I'm Rajdeep................

First of all, Hydrogen is a non-metal which can form a cation (positively charged ion) and hence it is placed in the metal reactivity series. It is present in Group 1 of First Period in the Modern Periodic Table.

Hydrogen is a diatomic gas which burns with a pale blue flame in air.


Now, to answer your question,

First let me tell what is an Isotope:
Atoms of the same element, with same atomic number but different mass number (due to difference in the number of electrons) are known as isotopes.


Hydrogen has three isotopes:

#1. Protium: Protium is the first isotope, which is the naturally occuring hydrogen present. It has only one proton in the nucleus and one electron in the K-shell and no neutrons. Hence, its atomic number is 1 and Mass number is also 1

#2. Deuterium: Deuterium is the second isotope. It has one proton in the nucleus and one electron in the K-shell, and one neutron. Hence, its atomic number is 1 and Mass number is 2.

#3. Tritium: Tritium is the third isotope. It has one proton in the nucleus and one electron in the K-shell, and two neutrons. Hence, its atomic number is 1 and mass number is 3.


HOPE MY ANSWER IS SATISFACTORY....
