Understand Covalent Bonds and Structures

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

The octet rule states that atoms are most stable when they have eight electrons in their outer shell.

Oxygen has 6 valence electrons.

Shared electrons allow atoms to achieve a full outer shell, leading to stability.

A molecule is a group of two or more atoms bonded together by covalent bonds.

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

The molecular formula for carbon dioxide is CO2.

The stability of an atom increases when it forms a covalent bond, as it achieves a full outer shell.

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

Yes, covalent bonds can form between different elements, resulting in compounds.
