Electron Configuration

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 are the main energy levels in electron configuration?

Back

The main energy levels are denoted by principal quantum numbers (n), which can be 1, 2, 3, etc.

Front

What is the maximum number of electrons in a principal energy level?

Back

The maximum number of electrons in a principal energy level is given by the formula 2n².

Front

What are the four types of orbitals?

Back

The four types of orbitals are s, p, d, and f, each with different shapes and capacities for holding electrons.

Front

How many electrons can an s orbital hold?

Back

An s orbital can hold a maximum of 2 electrons.

Front

How many electrons can a p orbital hold?

Back

A p orbital can hold a maximum of 6 electrons.

Front

What is the significance of the Aufbau principle?

Back

The Aufbau principle states that electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

What is Hund's rule?

Back

Hund's rule states that electrons will fill degenerate orbitals (orbitals of the same energy) singly before pairing up.

Front

What is the Pauli Exclusion Principle?

Back

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers.

Front

What is a noble gas configuration?

Back

A noble gas configuration refers to an electron configuration that is similar to that of the noble gases, often resulting in greater stability.
