Back

A model that describes metals as a lattice of positively charged ions surrounded by a sea of delocalized electrons that are free to move.

Front

What property of metals is explained by the electron sea model?

Back

The properties of metals, such as conductivity and malleability, are due to the movement of free electrons within the metal.

Front

What is the significance of the octet rule in chemistry?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons, leading to stability.

What is a strong acid?

Back

A strong acid is an acid that completely dissociates in solution, releasing all of its hydrogen ions.

Front

What is a weak acid?

Back

A weak acid is an acid that partially dissociates in solution, releasing some but not all of its hydrogen ions.
