Lesson 26

Today we covered chemical bonding! A chemical bond is an attraction between atoms that holds them together in space. Something important to know is that the electrons among atoms account for many properties of substances. Vocab time! Ionic bonding: a type of chemical bonding that is the result of transfer of electrons from one atom to another. Covalent bonding: chemical bonding in which one or more pairs of valence electrons are shared between the atoms covalent bonding can be molecular covalent or network covalent. Metallic bond: bond between metal atoms in which the valence electrons are free to move throughout the substance. Molecule: group of atoms covalently bonded together.

*A chart to help!! :)

~Metal atom - metallic

~Nonmetal atoms- network covalent OR molecular covalent

~Both- ionic
