Question

What can happen when a hydrogen atom absorbs energy?

विकल्प

• Its electron must remain in the ground state.

• Its electron can jump from the ground state to a higher orbit.

• Its electron must jump to the innermost orbit.

• Its electron must become completely free from the atom.

Answer 1

Absorbed energy can raise the electron from the ground state to a higher orbit. The atom is then in an excited state.
