Front

What does an arrow represent in an orbital diagram?

Back

An electron.

Front

What occurs when an electron drops from a higher to a lower energy level?

Back

Emission of light from an atom.

Front

What must an electron do to change from ground state to an excited state?

Back

Absorb energy.

Front

In which two orbitals are valence electrons located?

Back

s and p.

Front

Which element is represented by the orbital diagram for Chlorine?

Back

Chlorine.

Front

What is the ground state of an electron?

Back

The lowest energy state of an electron in an atom.

Front

What is an excited state of an electron?

Back

A state where an electron has absorbed energy and moved to a higher energy level.

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the significance of the 's' and 'p' orbitals?

Back

They are the orbitals that contain valence electrons.

Front

What happens to an electron when it falls into the nucleus?

Back

It is not a typical behavior; electrons do not fall into the nucleus due to quantum mechanics.
