What is a diatomic element?

Back

A diatomic element is a molecule composed of two atoms, which can be of the same or different chemical elements.

What type of bond is formed between sodium (Na) and chlorine (Cl)?

Back

Ionic bond.

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 double bond?

Back

A double bond is a type of covalent bond where two pairs of electrons are shared between two atoms.

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 significance of electronegativity in covalent bonding?

Back

Electronegativity is a measure of an atom's ability to attract shared electrons; it influences the type of covalent bond formed (polar or nonpolar).
