Strong (hard to break) but malleable(bent or hammered to different shapes; good conductors of heat and electricity; high melting and boiling points (except alkali metals)
1 of 12
Four properties of non-metals
dull looking, usually not solid at room temperature,more brittle, lower density, don't generally conduct electricity
2 of 12
Five properties of transition metals
Can have more then one ion, coloured compounds,often good catalysts, dense,shiny
3 of 12
Four properties of alkali metals
Low melting and boiling points (than other metals), soft/easily cut as low densities (lithium,sodium, and potassium float on water), hydroxides and oxides dissolve in water to produce alkaline solutions
4 of 12
Three properties of halogens
brittle (crumble when solid), have coloured vapours, diatomic (exist as molecules which are pairs of atoms)
5 of 12
What is a displacement reaction?
Can occur between a more reactive halogen and salt of a less reactive one.
6 of 12
aqueous solution
a solution of which the solvent is water
7 of 12
colour vapours of halogens
Fluorine is yellow gas, chlorine is green gas,bromine is reddy-brown volatile liquid,iodine is dark grey crystalline solid or purple vapour
8 of 12
Four properties of noble gases
Full outer shell of 8 electrons (except helium, full first shell), monoatomic gases-single atoms not bonded to each other,colourless gases at room temp,inert (non-reactive)
9 of 12
Trends of reactivity of noble gases
Boiling point increases as you move down swell as relative atomic mass
10 of 12
Trends of reactivity of alkali metals
As you move down:increasing reactivity, lower MP and BP points, higher relative atomic mass
11 of 12
Trends of reactivity of halogens
As you go down group: less reactive, higher BP and MP points, higher relative atomic mass
