Chemical Bonds

Front

What are chemical bonds?

Back

Chemical bonds are the forces that hold atoms together in a molecule or compound. They can be ionic, covalent, or metallic.

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, typically between a metal and a nonmetal.

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, usually between nonmetals.

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 around.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

Why don't noble gases form bonds?

Back

Noble gases do not form bonds because they have a full octet of electrons in their outer shell, making them stable and unreactive.

What is the ionic charge of a hydrogen ion?

Back

The ionic charge of a hydrogen ion (H+) is +1.

Front

What elements generally form ionic bonds?

Back

Ionic bonds typically form between metals and nonmetals.

Front

What is the ionic charge of a chlorine ion?

Back

The ionic charge of a chlorine ion (Cl-) is -1.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where the electrons are shared unequally between the two atoms, resulting in a molecule with a slight charge.
