Question

Hydrogen has three isotopes 1H, 2H, and 3H. What is the difference between these three isotopes?

Answer 1

The number of neutrons
and the mass number

Answer 2

Answer:

the differences are: molecular weight, neutron number, melting point and boiling point.

Explanation:

Isotopes are elements that have the same number of protons. There are 3 known hydrogen isotopes, the propium (H, which is hydrogen itself), deuterium (2H, commonly called D) and tritium (3H, commonly called T), which, although they have very similar characteristics, have some characteristics. different, such as molecular weight, neutron number, melting point and boiling point.

• 1H: has a molecular weight of 1,0079 g; It has a neutron number of zero, a melting point of 20.3 K and a boiling point of 100 ° C.
• 2H: has a molecular weight of 2.0141 g; It has a neutron number of 1, a melting point of 23.6 K and a boiling point of 101.4 ° C.
• 3H: has a molecular weight of 3.0164 g; has a neutron number of 2, melting point equal to 25.1 K and a boiling point of 102.9 ° C.
