What is electron configuration of H2SO4?

Answer 1

We use electron configuration for atoms or ions. You can't use it for compounds.

Answer 2

The electron configuration of sulfur (S) in H2SO4 is 1s2 2s2 2p6 3s2 3p4. This is because sulfur has 16 electrons and the electron configuration follows the rules of filling orbitals from the lowest energy level to the highest.
