bond
Definition
A bond is a force that holds two atoms together. The strength of a bond depends on the type of bond and the atoms involved.
There are three main types of bonds: ionic bonds, covalent bonds, and metallic bonds.
Ionic bonds are formed when one atom donates an electron to another atom. The atom that donates the electron becomes a positively charged ion, and the atom that receives the electron becomes a negatively charged ion. The oppositely charged ions are attracted to each other, forming an ionic bond.
Covalent bonds are formed when two atoms share electrons. The shared electrons are attracted to the nuclei of both atoms, holding the atoms together.
Metallic bonds are formed when metal atoms share their electrons with each other. The shared electrons form a "sea" of electrons that surrounds the metal atoms. The metal atoms are attracted to the sea of electrons, holding them together.
How can the word be used?
The atoms in a molecule are held together by chemical bonds.

Etymology
The word "bond" has a long and interesting etymology. It comes from the Old English word bond, which means "a tie or fastening." The Old English word bond is thought to be related to the Proto-Germanic word band, which also means "a tie or fastening.".

AQA Science Exam Question and Answer
Question:
What is a "chemical bond," and how does it form between atoms?
Answer:
A chemical bond is a force of attraction that holds atoms together in a molecule or a compound. It forms when atoms share electrons or transfer electrons from one atom to another, resulting in a stable arrangement of outer electrons, also known as a full valence electron shell. The types of chemical bonds include covalent bonds, where atoms share electrons, and ionic bonds, where atoms transfer electrons to form oppositely charged ions that are attracted to each other.
