Front

Define a covalent bond.

Back

A covalent bond is a chemical bond formed by the sharing of electron pairs between atoms.

Front

What is an ionic bond?

Back

An ionic bond is a chemical bond formed through the transfer of electrons from one atom to another, resulting in the formation of charged ions.

Front

What is the difference between a molecule and a compound?

Back

A molecule is two or more atoms bonded together, while a compound is a type of molecule that contains at least two different elements.

What is the significance of the chemical formula H₂O?

Back

It indicates that each molecule of water is composed of two hydrogen atoms and one oxygen atom.

Front

What is the octet rule?

Back

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