Question

How many neutrons are in a typical silicon atom?
A.28
B.15
C.42
D.14

Answer 1

14 neutrons are present in silicon

Answer 2

Hey!

_____________

Correct answer - D) 14 Neutrons
A typical silicon atom has 14 Neutrons, 14 electrons and 14 protons.

Explaination - Atomic number of silicon is 14.
We know,

Atomic number = Number of Electrons = Number of protons

And atomic mass = Number of protons + Number of neutrons

and atomic mass of silicon = 28
So,

28 = 14 + number of neutrons
number of neutrons = 14

That's all!
