Unit 3 Electron Configuration Flashcard

Front

What is the Aufbau principle?

Back

The Aufbau principle states that each electron occupies the lowest energy orbital available.

Front

How many electrons can fit in each atomic orbital?

Back

A maximum of 2 electrons can occupy each atomic orbital.

Front

What is Hund's Rule?

Back

Hund's Rule states that single electrons will fill up empty orbitals first before pairing up with opposite spins.

Front

What does the Pauli exclusion principle state?

Back

The Pauli exclusion principle states that a maximum of 2 electrons can occupy a single atomic orbital and only if they have opposite spins.

Front

What is an orbital diagram?

Back

An orbital diagram is a visual representation of the electron configuration of an atom, showing the distribution of electrons in orbitals.

Front

What is the electron configuration for Sulfur?

Back

The electron configuration for Sulfur is [Ne] 3s2 3p4.

Front

What is the significance of the noble gas notation in electron configuration?

Back

Noble gas notation simplifies electron configurations by using the electron configuration of the nearest noble gas to represent core electrons.

Front

What is the maximum number of electrons in a p subshell?

Back

The maximum number of electrons in a p subshell is 6.

Front

What is the shape of s orbitals?

Back

s orbitals have a spherical shape.

Front

What is the shape of p orbitals?

Back

p orbitals have a dumbbell shape.
