WebThe two atoms are held together because losing an electron makes the sodium atom positively charged, while gaining an electron makes the chlorine atom negatively charged – and opposite charges attract. This is known as ‘ionic bonding’. Another way of bonding is to share electrons – ‘covalent bonding’. For example, oxygen atoms need ... http://www.chem4kids.com/files/atom_bonds.html

WebOct 18, 2024 · In contrast to intra molecular forces, such as the covalent bonds that hold atoms together in molecules and polyatomic ions, inter molecular forces hold molecules together in a liquid or solid. Intermolecular forces are … WebBonds hold atoms together within molecules. A molecule is a group of atoms that associates strongly enough that it does not dissociate or lose structure when it interacts with its environment. At room temperature two nitrogen atoms can be bonded (N 2). Bonds break and form during chemical reactions. In the chemical reaction called fire, bonds ...
