Question

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?

Answer 1

Answer:

C:Si =3:7

Explanation:

no. of neutrons in C=6

no. of neutrons in Si=14

Ratio=6/14 =3/7

Hence, C:Si=3:7

Answer 2

Answer: 3:7

Explanation:

as number of neutrons in carbon is 6 and number of neutrons in Silicon is 14 so when we do the Calculation and find the ratio of their number of neutrons we get the answer 3 ratio 7(3:7)
