|---|---|---|---|---|---|
| periodic law | when elements are arranged in order of insreasing atomic number, there is a periodic repetition of their physical and chemical properties
🗑

| metals | high luster,good conductors of heat and electricity, can reflect light b/c of luster/ sheen, solid at room temp. except for mercury(Hg), malleable and ductile
🗑
|
||||
| nonmetals | poor conductors of heat and electric current. Carbon =exception, solid nonmetals brittle(break when hit w/ hammer)
🗑
