Periodic Trends and Electron Configurations Review

Front

What does the Pauli exclusion principle state?

Back

A maximum of two electrons can occupy a single atomic orbital, but only if the electrons have opposite spins.

Front

What is the ground state of an atom?

Back

The state of an atom where all electrons are in the lowest possible energy levels.

Front

How can you determine the number of energy levels in an atom?

Back

By the Period in the periodic table.

Front

According to the Bohr model, how does the electron in a hydrogen atom move?

Back

The electron circles the nucleus in specific, allowed orbits.

Front

What is the electron configuration of Carbon?

Back

Front

What is the significance of the periodic table's periods?

Back

Each period corresponds to a new energy level for the electrons in the atoms.

Front

What does the term 'excited state' refer to in an atom?

Back

An excited state occurs when an electron absorbs energy and moves to a higher energy level.

Front

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

Back

Two electrons, with opposite spins.

Front

What is the relationship between electron configuration and chemical properties?

Back

The electron configuration determines how an atom interacts and bonds with other atoms.

Front

What does the term 'valence electrons' mean?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.
