Question

Oxygen, atomic number 8, is in Group 6A. How many orbitals are occupied by the valence electrons of O in its ground state?

................Orbital(s)

Answer 1

Oxygen have atomic number 8 so it have total 8 electron .

electronic configuration is $1s^2,2s^2, 2p^4$

outer valence shell is 2^n^d shell so it have 6 electron.

Oxygen occupied 4 orbitals(1s and 3 p orbital).
