Metals, Non-Metals, Metalloids

Metals
.shiny, solid (at room temperature)
.mallable-can be shaped
.high conductivity (good conductrors)(heat of electricity)
[Periodic Table:farther to the left->low, farther to the right->high]

Non-Metals
.not shiny
.not good conductors
.mostly gases
.brittle
.weak/easy to break
[Periodic Table: farther to the left->high, farther to the right->low]

Metalloids
.solid
.brittle
.hard
.semi-conductors
.important to computer chips
.silicon-in glass and sand
[Periodic Table: between metals and non-metals]

Facts:
Carbon-important element for making up living organisms.
Noble Gases-group 18- very non-reactive. Have full outer shells
Silicon Valley-place where all major computer makers are.
