Question

The atomic number of oxygen and sulfur are $8and16$ respectively. What will be the number of electrons in these?

Answer 1

1. The atomic number of $\mathrm{Oxygen}\left(\mathrm{O}\right)=8$

We know, $\mathrm{atomic}\mathrm{number}=\mathrm{Number}\mathrm{of}\mathrm{protons}=\mathrm{Number}\mathrm{of}\mathrm{electrons}$= $8$

Hence, the number of electrons present in $\mathrm{Oxygen}\left(\mathrm{O}\right)=8$

2. The atomic number of Sulfur$\left(\mathrm{S}\right)=16$

Now, $\mathrm{atomic}\mathrm{number}=\mathrm{Number}\mathrm{of}\mathrm{protons}=\mathrm{Number}\mathrm{of}\mathrm{electrons}$= $16$

Hence, the number of electrons present in $\mathrm{Sulfur}\left(\mathrm{S}\right)=16$
