In neutral atom,
Atomic number = No. of electron/proton.
If atomic no. is 5 then no. of electrons is also 5.
Atomic number = No. of electron/proton.
If atomic no. is 5 then no. of electrons is also 5.

1st orbit - Max 2.
2nd - Max 8.
3rd - Max 8.
4th - Max 18.
1st orbit - Max 2.
2nd - Max 8.
3rd - Max 8.
4th - Max 18.

In first orbit shares only 2 electron s^1 and s^2.

In neutral atom no of protons is equal to no of electrons that means the answer is as same as the atomic number of the atom.

1 st orbit = 2 electrons
2 nd orbit = 3 electron
atomic no = no.of protons in nucleus
there fore 2+3=5
2 nd orbit = 3 electron
atomic no = no.of protons in nucleus
there fore 2+3=5

@Karthikeyan.
How do share the electrons in 2 orbits? why not all 5 electrons in one outer orbit (y all are not valence electrons) ?

Because formula for no.of valance electron=2n*n so we share electrons in two orbit not all in one orbit.
