Answer:
Atomic Number = 37
Explanation:
Three Fully Filled Orbits of stable unipostive ion will have 2, 8, 18 ,8 in K, L, M, N respectively.
Note: Here N is not fully filled it can accommodate 32 electrons by Bohr Bury rule 2n². So, it's 3 fully filled orbits.
By stable we mean it has completed its octet. So, it's last shell that is N will have 8.
Unipostive means it must have losed one electron.
