What is a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

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.

Front

What is a dot diagram?

Back

A dot diagram (or Lewis structure) represents the valence electrons of an atom as dots around the chemical symbol.

Front

What is the difference between a single bond and a double bond?

Back

A single bond involves one pair of shared electrons, while a double bond involves two pairs of shared electrons.

Front

What is bond length?

Back

Bond length is the distance between the nuclei of two bonded atoms.
