Question

Two istopes of a hydrogen whose atomic weight respectively 1.0078 and 2.0143

Answer 1

Answer:

1. Protium (1H)
2. Deuterium (2H)

Explanation:

1. Protium is the most prevalent hydrogen isotope, with an abundance of 99.98%. It consists of one proton and one electron.

2. Deuterium is a hydrogen isotope consisting of one proton, one neutron and one electron. It has major applications in nuclear magnetic resonance studies.

There are actually 3 isotopes. The other one is TRITIUM (3H). Atomic mass 3.016049.

-Tritium is a hydrogen atom that has two neutrons in the nucleus and one proton. Tritium is produced naturally in the upper atmosphere when cosmic rays strike nitrogen molecules in the air. Tritium is also produced during nuclear weapons explosions, and as a byproduct in nuclear reactors.
