In chemistry what is a bond?

Answer 1

A bond is when two or more atoms join in some way:

Ionic Bonding - When two charged substances bond with each other and cancel out the charge

Covalent Bonding - The sharing of electrons between atoms

Metallic Bonding - Electrons in a metal are shared by all atoms

There are more but I've only just started chemical bondings

Answer 2

In chemistry, bonds hold atoms together to make molecules (intramolecualr bonding), and hold molecules together to make the substances we can see and touch (intermolecular bonding). For example, covalent bonds (electron-sharing bonds) hold two hydrogens and an oxygen together to make water. Then, hydrogen bonding forces hold the water molecules together. Another example is salt (NaCl). Sodium and chlorine are held together by ionic bonds (two ions of oppsite charges are attracted to each other), and then the NaCl molecules are held together by dipole-dipole forces.
