Unit 3 Electron Configuration Flashcard

Front

What is Hund's Rule?

Back

Single electrons will fill up empty orbitals first, then pair up with opposite spins.

Front

Where are the periods found on the periodic table?

Back

Horizontally in rows.

Front

What is the Pauli Exclusion Principle?

Back

No two electrons in an atom can have the same set of four quantum numbers.

Front

What is an atomic orbital?

Back

A region in an atom where there is a high probability of finding electrons.

Front

What is the maximum number of electrons that can occupy a single atomic orbital?

Back

2, with opposite spins.

Front

What is the significance of the Aufbau Principle?

Back

Electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

How do you determine the number of valence electrons in an element?

Back

By looking at the group number in the periodic table.
