1
A getting to know you session of the elements.
Properties A getting to know you session of the elements.
2
Physical Properties Aspects of an object or substance that can be observed and/or measured without changing it. E.g. The boiling point of water is 100 °C.
3
Physical Properties Melting point: the temperature at which a solid changes into a liquid. Boiling point: the temperature at which a liquid changes into a gas.
4
Physical Properties Conductivity: the ability of a substance to allow heat or an electric current to flow through it. Solubility: the degree to which a substance will enter into solution (dissolve). Malleable: if a material can be hammered into sheets.
5
Physical Properties Ductile: if a material can be drawn into a wire.
Hardness: the ability of a material to resist scratching or denting. Flexible or brittle: a material’s ability to bend easily or snap when bent. Lustre: a material’s ability to reflect light especially when polished. I.e. shiny or dull.
7
Metals
8
Metals Metals have the following properties:
Solid at room temperature (except mercury) High melting and boiling points (except mercury) Are malleable and ductile Are usually lustrous and can be polished Metals conduct electricity Metals are flexible
9
Non-metals
10
Non-metals Non-metals have the following properties:
Usually gases or liquids at room temperature Low melting and boiling points Are not malleable or ductile Do not have a metallic lustre Are brittle and break when subjected to stress and strain
11
Metalloids
12
Metalloids Possess some characteristics of metals and some of nonmetals. Generally they have physical characteristics of a metal, but behave chemically more like non-metals.
