Front

Define excited state in terms of electron configuration.

Back

An excited state occurs when an electron absorbs energy and moves to a higher energy level, resulting in a configuration different from the ground state.

Front

What is the significance of the ground state electron configuration?

Back

The ground state configuration represents the lowest energy arrangement of electrons in an atom, which is crucial for understanding chemical reactivity.

Front

How does the electron configuration change for a cation?

Back

For a cation, electrons are removed from the outermost shell, resulting in a configuration with fewer electrons than the neutral atom.

What is the electron configuration for a neutral magnesium atom?

Front

Explain how to determine the excited state configuration from the ground state configuration.

Back

Start with the ground state configuration, then move one or more electrons to higher energy levels while ensuring the total number of electrons remains the same.
