A) 19
B) 20
C) 21
D) 20.1797
Answer:
Option D) 20.1797 is correct.
Explanation:
Atomic Mass of any substance is the sum of the number of protons and the number of neutrons in the nucleus of that atom.
For Neon,
- Number of Protons = 10
- Number of Neutrons = 10
Thus,
Atomic Mass of Neon = 10 + 10 = 20
Neon is a noble gas and its electronic configuration is, 2, 8. In absolute terms, the average atomic mass of Neon is 20.1797 amu. It is calculated taking into account all the isotopes of Neon.
