Question

Calculate the ratio of number of neutrons
1)in carbon-12&silicon
2)in Fluorine&Neon ​

Answer 1

Answer:

Carbon,

Atomic Number =6= Electrons = Protons

Neutrons = Mass Number − Protons=12−6=6

Silicon,

Atomic Number=14=Electrons = Protons

Neutrons = Mass Number − Protons =28−14=14

Ratio =6:14 or 3:7

Answer 2

Explanation:

Atomic Number =6= Electrons = Protons

Neutrons = Mass Number − Protons=12−6=6

Silicon,

Atomic Number=14=Electrons = Protons

Neutrons = Mass Number − Protons =28−14=14

Ratio =6:14

or 3:7
