METAL NON METAL Alkali Alkaline Earth Metals Transition Metalloids
Noble Gases Transition NON METAL Halogens Metalloids
2
Alkali Metals +1 Sodium Chemical Properties Very Reactive Potassium
Good conductor of heat Good conductor of electricity Can explode if exposed to water Low melting and boiling temperature Low density Potassium Physical Properties All solid at room temperature Malleable Ductile Silvery coloured Lustrous +1 Lithium
3
Alkaline Earth Metals +2 Chemical Properties
Very reactive (less so than Alkalis) Good conductor of heat Good conductor of electricity Physical Properties Harder and Denser than Alkalis Lustrous Silvery-white colour All solid at room temperature Beryllium Calcium Magnesium
4
Transition Physical Properties Very hard Malleable Ductile Lustrous
Most are solid at room temperature Chemical Properties High melting and boiling point High conductivity Less reactive than Alkali and Alkaline Metals Good conductor of heat Good conductor of electricity Titanium Mercury
5
Metalloids Chemical Properties
Gives electrons to non-metals and takes electrons from metals. Metalloids Chemical Properties Better conductor than non-metals but worse than metals Better conductors at high temperatures Polonium is radioactive Physical Properties Shiny or Dull Malleable Ductile Solid at room temperature Contains properties of both metals and non-metals Arsenic Silicon Germanium
6
Halogens -1 Chemical Properties Very reactive High ability to oxidize
Fluorine and Chlorine are poisonous Bromine is toxic Astatine is radioactive Fluorine is the most reactive element Halogens -1 Physical Properties Fluorine is a pale yellow gas Chlorine is a pale green gas Bromine is a brown liquid Iodine is a lustrous black solid Astatine is a solid Bromine Fluorine Chlorine
7
Noble Gases Chemical Properties Almost completely non-reactive
Low boiling point Helium has lowest boiling point of any substance Radon is radioactive Noble Gases Physical Properties All gases at room temperature Helium Xenon Argon
