Question

A bond is formed between two carbon atoms when four electrons are shared between them.

Answer 1

The sharing of electrons between two atoms in a molecule leads to the formation of bond(s) between them.

• When two atoms share two electrons between them in a molecule, a single bond is formed between them. For example, a hydrogen molecule.
• When two atoms share four electrons between them in a molecule, a double bond is formed between them. For example, an oxygen molecule.
• When two atoms share six electrons between them in a molecule, a triple bond is formed between them. For example, a nitrogen molecule.
