Answer 1

Answer:

4️⃣ Ne

Explanation:

I think it's help you

thank you

Answer 2

NE

Sulphur

has the maximum atomic radius when compared to the other three atoms. Also the electronic configuration of sulphur is [Ne]3s23p4. By losing one electron, sulphur can attain the half filled state and hence achieve greater stability. Hence, sulphur has the least ionization enthalpy in this case.
