Front

What is a valence electron?

Back

A valence electron is an electron that is located in the outermost shell of an atom and can participate in forming chemical bonds.

Front

How do atoms achieve a full outer shell?

Back

Atoms achieve a full outer shell by gaining, losing, or sharing electrons through ionic or covalent bonding.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What happens to an atom when it loses electrons?

Back

When an atom loses electrons, it becomes a positively charged ion (cation).

Front

What happens to an atom when it gains electrons?

Back

When an atom gains electrons, it becomes a negatively charged ion (anion).

Front

How many valence electrons does Calcium (Ca) have?

Back

Calcium (Ca) has 2 valence electrons.

Front

What charge does a Calcium ion (Ca²⁺) have?

Back

A Calcium ion (Ca²⁺) has a charge of +2.

Front

How many valence electrons does Phosphorus (P) have?

Back

Phosphorus (P) has 5 valence electrons.

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 8 electrons.
