Bonds

Definition

In chemistry, bonds refer to forces holding together atoms within molecules. There are three main types - covalent (sharing), ionic (transferring), and metallic (pooling).

Analogy

Bonds can be thought about like friendships. Covalent bonds are like best friends who share everything equally; ionic bonds are more one-sided friendships where one friend gives more than the other; and metallic bonds are like a group of friends who pool their resources together for everyone's benefit.
