If the atomic weight of C and Si are 12 ...

If the atomic weight of C and Si are `12` and `28` respectively , then what is the ratio of the number of neutrons in them?

A

`1:2`

B

`2:3`

C

`3:4`

D

`3:7`

Text Solution

Verified by Experts

Number of neutrons in `_(6)C^(12) = 12 - 6 = 6`
Number of neutrons in `_(14)Si^(20) = 28 - 14 = 14`
The ratio of the number of neutrons in C and `Si` is `6:14 or 3:7`
