Atomic Mass of Helium is ____________.
A) 6
B) 4
C) 5
D) 3
Response:
Alternative B) 4 is proper.
Description:
Atomic Mass of any compound is the amount of the variety of protons and the variety of neutrons in the nucleus of that atom.
For Helium Atom,
- Variety Of Protons = 2
- Variety Of Neutrons = 2
Hence,
Atomic mass of Helium = 2 +2 = 4
In outright terms, the typical atomic mass of Helium is 4.002602 u, which is the proportional mass of its 2 steady isotopes. The 2 steady isotopes of the Helium is,
- Helium-3 ( 2 He 3)
- Helium-4 ( 2 He 4) (* ) Last Upgraded: (* ) 01 May, 2023 (* ) Like Short article
