Chemical Bonding

What is a chemical bond?

Back

A chemical bond is a lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds.

Front

What are the three main types of chemical bonds?

Back

The three main types of chemical bonds are ionic bonds, covalent bonds, and metallic bonds.

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 is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, characterized by a 'sea of electrons' that are free to move.

Front

What are valence electrons?

Back

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

Front

How many valence electrons do Noble Gases have?

Back

Noble Gases have 8 valence electrons, making them stable and unreactive.

Front

What happens to an atom when it loses an electron?

Back

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

Front

What happens to an atom when it gains an electron?

Back

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

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.
