Topic 4 Flashcards
Identify properties of metals
malleable, ductile, good conductors (heat & electricity)
Identify properties of non metals
Low Conductivity, less ductile, less density
Identify properties of semimetals
Lower conductivity, fewer charge carriers than metals
Identify ‘Ductile’
Ability to stretch into wires without breaking
Identify ‘Malleable’
Ability of an element to be pressed/hammered without breaking
Identify ‘Conductivity’
Ability of an element to let electricity & heat flow through
Identify ‘Reactivity’
How easily an element reacts to substances
Identify ‘Lustre’
The shininess of a elements surface
Outline key features of ‘halogens’ & ‘noble gases’
The halogens are nonmetals found in group 17 of the periodic table, The noble gases are nonmetals found in group 18 of the periodic table, they are invisible.
