Atoms Molecule

Neon Ne, Helium He

Inorganic compounds ( AKA Salts ) Formed when a metal combines with one or more nonmetals Solids at room temperature but most will dissolve in water. Examples: Table Salt – Sodium Chloride – NaCl Road Salt – Calcium chloride - CaCl 2 Chalk – Calcium carbonate – CaCO 3

Ionic bonds form when one atom gives up one or more electrons to another atom. Metals tend to give up electrons and become positively charged Called cations Nonmetals tend to accept or gain electrons and become negatively charged Called Anions Example – Table salt which is sodium chloride (NaCl)

Type of Matter ElementCompound Individual Atoms 2 or more like atoms combined Example: Oxygen O 2, Sulfur S 8 Atoms of At least 2 different elements bonded Example: Water H 2 O Glucose C 6 H 12 O 6 Example: Helium He Neon Ne Could be: Must be

Type of Particle AtomMolecule Single atoms not bonded to any others Example: Neon Ne Helium He Could be: Two or more atoms bonded together Example: Oxygen O 2 Water H 2 O Glucose C 6 H 12 O 6
