S₂O₃.

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

What is a polar covalent bond?

Back

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

Front

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

Back

A single bond involves one pair of shared electrons, a double bond involves two pairs, and a triple bond involves three pairs.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.
