Question | Answer |
---|---|
properties of a metal | malleable, ductile, good conductor, reactive, corrosive |
corrosion | metal reacts with oxygen |
Group 1 - alkali metals | most reactive metal group |
metal | mostly in solid state |
metal reactivity | decreases left to right |
magnesium and calcium | most abundant alkaline earth metals (group 2) |
nonmetal | mostly in gas state |
properties of nonmetal | poor conductor, reactive, dull, brittle |
diatomic molecule | element that consists of two of the same atoms |
Group 17 (Halogens) | most reactive nonmetal group |
Group 19 (Noble Gases) | nonmetals that do not react |
properties of a metalloid | solids, brittle, hard, somewhat reactive |
metalloids | located on "zigzag" - between metals and nonmetals |
