Fashioned For You

Elements can be divided into two classes:
1)Metals
2)Non Metals

Properties Of Metals:
1) Have lusture
2) Opaque - Liquid cannot pass through
3) Hard
4) Strong
5) Hard wearing, last long
6) Malleable - Can be hammered into shapes
7) Ductile - Can be drawn into wires
8) Good conductor of electricity and heat

Short terms of elements:
1) Meth
2) Eth
3) Prop
4) But
5) Pent
6) Hex
7) Hept
8) Oct
9) Non
10) Dec

Second part of SCI 10

1) Is a good conductor of electricity
2) Sonorous - produce ringing sound when hit
3) Usually solid at room temperature
4) High density - usually heavy
5) Form basic oxides
6) high melting point
7) Ions of metals have positive charges

Exceptions:
Sodium is a soft metal of low density

Properties of Nonmetals:

1) Dull - Not shiny
2) Soft
3) Brittle - Breaks easily
4) low density - light
5) poor or non conductor of heat and electricity
6) usually liquids or gasses
7) low melting point
8) form acidic oxide
9) some ions have negative ions other are neutral


Oxide is a binary compound of oxygen and another element or group.
