Question

give increasing energy order of subshells of P and Cl​

Answer 1

Answer:

hey dear

The order is Si<S<P<Cl

Generally, ionisation energy increases with atomic number in a period as we move from left to right. But as P has the stability of half-filled 'p' orbital, it has greater ionisation energy than S which has 4 electrons in 3p level and would readily lose the extra electron to acquire the stable half-filled 3p orbital.
