Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have a full set of eight valence electrons, achieving a stable electron configuration.

Front

How many valence electrons does Aluminum have?

Back

Aluminum has 3 valence electrons.

Front

What charge does Aluminum have after it loses electrons to form an octet?

Back

Aluminum has a +3 charge after losing 3 electrons.

Front

Why do alkali metals behave similarly?

Back

Alkali metals behave similarly because they all want to get rid of 1 electron to achieve a stable electron configuration.

Front

What are cations?

Back

Cations are positively charged ions that are formed when an atom loses one or more electrons.

Front

What happens to oxygen when it gains two electrons?

Back

When oxygen gains two electrons, it achieves a stable electron configuration similar to that of Neon.

Front

Which element loses 1 electron to attain an octet?

Back

Potassium loses 1 electron to attain an octet.

Front

What is the charge of a cation?

Back

The charge of a cation is positive.

Front

What is the electron configuration of Neon?

Back

The electron configuration of Neon is 1s² 2s² 2p⁶, which means it has a full outer shell.

Front

What is the significance of valence electrons?

Back

Valence electrons are important because they determine how an atom will bond with other atoms.
