Front

What is the chemical formula of tetraphosphorus heptaoxide?

Back

P₄O₇.

Front

Define 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 form bonds until they are surrounded by eight valence electrons.

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 the molecular shape of a molecule with four bonding pairs and no lone pairs?

Back

Tetrahedral.

Front

What is the significance of electronegativity in covalent bonding?

Back

Electronegativity determines how strongly an atom attracts shared electrons in a bond.
