What is the Atomic Mass of Silicon?
Atomic Mass of Silicon is .
A) 28
B) 29
C) 27
D) 30
Answer: The atomic mass of Silicon is 28 amu. Therefore, the correct option is A.
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 Silicon,
Number of Protons = 14
Number of Neutrons = 14Thus,
Atomic Mass of Silicon = 14 + 14 = 28
In absolute terms, the average atomic mass of Silicon is 28.0891 amu. It is calculated taking into account all the isotopes of Silicon.
The three naturally occurring isotopes of silicon are,
- 28Si
- 29Si
- 30Si
