Consider the spectrum for the hydrogen atom. In which situation will light be produced ?

Electrons release energy as they return to the ground state.

Electrons absorb energy as they move to an excited state.

Electrons release energy as they move to an excited state.

Electrons absorb energy as they return to the ground state.

packets of electromagnetic energy

When radiation burst through electric waves

The emission of electrons from a metal caused by light striking the metal

The rate at which a waves energy flows through a given unit of area.

Jerick, Amada, Eric, Leina, and Sophie are studying chemistry together. They are discussing Hund's rule. According to Hund's rule, what happens when electrons occupy an energy orbital?

Jerick suggests that single electrons with the same spin must occupy each-energy orbital before additional electrons with opposite spins can occupy the same orbitals

Amada thinks that each electron occupies the lowest energy orbital available

Eric believes that a maximum of two electrons can occupy a single atomic orbital, but only if the electrons have opposite spins

What does Pauli exclusion principle state ?

states that -no two electrons in the same orbital can have the same spin

states that each electron occupies the lowest energy orbital available

states that single electrons electrons with the same spin must occupy each-energy orbital before additional electrons with opposite spins can occupy the same orbitals
