Electron Configuration, Orbital Diagrams, and Lewis Structures

Front

What does Hund's rule state?

Back

Hund's rule states that single electrons with the same spin must occupy each energy orbital before additional electrons with opposite spins can occupy the same orbitals.

Which atom has the electron configuration 1s² 2s² 2p⁶ 3s²?

Back

The atom is Magnesium.

Front

What does the Pauli exclusion principle state?

Back

The Pauli exclusion principle states that a maximum of two electrons can occupy a single atomic orbital, but only if the electrons have opposite spins.

What is the noble gas configuration for phosphorus?

Back

The noble gas configuration for phosphorus is [Ne] 3s² 3p³.

Front

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

Back

A maximum of two electrons can occupy a single orbital.

Front

What is the significance of the electron configuration in chemistry?

Back

The electron configuration determines the distribution of electrons in an atom, which influences its chemical properties and reactivity.

Front

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

Back

The number of valence electrons can be determined from the outermost electron shell of the atom.

Front

What is the shape of the s orbital?

Back

The s orbital has a spherical shape.

Front

What is the shape of the p orbital?

Back

The p orbital has a dumbbell shape.
