Answer 2

Answer:

Refer to attachment please.

• If the atomic number of oxygen is 8 then the number of electron will be 8.

We know that "Atomic number = Electron = Proton" In K shell there are two electrons of oxygen present and in L shell six electrons are present. $\:$

Additional information:

How are Electrons distributed in different shells or orbits!?

1) The maximum number of electrons present in orbit is given by a formula that is mentioned below: 2n², where ‘n’ is the orbit or shell or the level of index that is 1,2,3,4,... Using this formula we can find out the maximum number of electrons present in orbit like K, L, M, N...etc.

2) In the outermost shell only 8 electrons are accomodated.

3) If the first shell isn't fill then we can't fill the other shells. That is the shells are filled in a step wise way.
