Electron Configuration & Groups on the Periodic table

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating the energy levels and sublevels occupied by electrons.

Front

What is the Pauli Exclusion Principle?

Back

A principle stating that no two electrons in an atom can have the same set of four quantum numbers.

Front

What is Hund's Rule?

Back

A rule stating that electrons will occupy degenerate orbitals singly before pairing up, to minimize repulsion.

Front

What does the Aufbau Principle state?

Back

Electrons fill orbitals starting from the lowest energy level to the highest.

Front

What is the significance of the periodic table groups?

Back

Elements in the same group have similar chemical properties and the same number of valence electrons.

Front

How many electrons can the s orbital hold?

Back

The s orbital can hold a maximum of 2 electrons.

Front

How many electrons can the p orbital hold?

Back

The p orbital can hold a maximum of 6 electrons.

Front
