Ch 5 20 Q - Rules of Stability

Front

What is the most stable electron configuration?

Back

A filled sublevel is the most stable electron configuration.

Front

Which electron configuration is more stable: one that ends with d² or s²?

Back

A configuration that ends with s² is more stable.

Front

What is the reactivity of an electron configuration that ends with 3p⁵?

Back

The configuration 1s² 2s² 2p⁶ 3s² 3p⁵ is more reactive than 1s² 2s² 2p⁶ 3s² 3p³.

Front

What is a half-filled sublevel?

Back

A half-filled sublevel has exactly half of the maximum number of electrons in that sublevel, which can provide stability.

Front

Which is more reactive: a configuration ending with 2p² or 2p³?

Back

A configuration that ends with 2p² is more reactive.

Front

What is the significance of electron configurations in determining stability?

Back

Electron configurations help predict the stability and reactivity of elements based on their arrangement of electrons.

Front

Define a filled sublevel.

Back

A filled sublevel is one that contains the maximum number of electrons allowed for that sublevel.

Front

What does it mean for two configurations to be equally stable?

Back

Two configurations are equally stable if they have similar energy levels and electron arrangements.

Front

How does the stability of electron configurations affect chemical properties?

Back

The stability of electron configurations influences how elements interact, bond, and react with other substances.

Front

What is the role of valence electrons in stability?

Back

Valence electrons are the outermost electrons and play a crucial role in determining an atom's stability and reactivity.
