Ions and Valence Electrons

Front

What is an ion?

Back

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

How do you determine the charge of an ion?

Back

The charge of an ion is determined by the difference between the number of protons (positive charge) and electrons (negative charge).

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with other atoms, influencing the formation of molecules.

Front

What is the octet rule?

Back

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

Front

What is a cation?

Back

A cation is a positively charged ion that is formed when an atom loses one or more electrons.
