what is the atomic number? number of protons what are isotopes? atoms with the same atomic number but different masses and different number of neutrons how do you find number of electrons an atom has? by the number of protons it has no charge,if it has a charge determine it by (-) = add electron (+) = subtract electron how do you find number of neutrons? atomic mass - protons Covalent bonding? a. metal and metal b. nonmetal and nonmetal c. nonmetal and metal b. nonmetal and nonmetal ionic bonding? a. metal and metal b. nonmetal and nonmetal c. nonmetal and metal c. metal and non metal metallic bonding? a. metal and metal b. nonmetal and nonmetal c. nonmetal and metal a. metal and metal Chemical Properties characteristics that require chemical change in composition Physical properties characteristics that can be observeed without changing composition which is a chemical property? a. boiling point b. volume c. burning d. conductivity c. burning which is a physical property? a. reactivity b. malleability c. corrosion d. rusting b. malleability what is an intensive property? they DO NOT rely on the amount of a substance what is an extensive property? they DO rely on the amount of a substance what are 3 examples of the intensive properties? color density melting point what are 3 examples of the extensive properties? mass size volume
