Chemical Properties of Matter

• Flammability - ignites easily at ambient temperature
• combustibility - can burn in air under certain conditions
• reactivity - tendency to combine chemically with other substances
• toxicity - extent to which a chem element may harm an organism
• chemical stability - thermodynamic stability of a chemical system
• acidity - react with an acid
• coordination number - number of atoms bonded to the atom
• Chemical bonds are the strongest bonds in the universe and are formed when electrons are transferred from one atom to another
• enthalpy - heat released/absorbed from elements at constant pressure
• oxidation state - measure of the loss of electrons or oxidation
• degree of ionization is the number of electrons lost by an atom in a chemical reaction
