C1 : Transition Elements

Question 1

Group 1

Answer 1

. Soft metals (can be cut with a knife)
. Relatively low melting points
. Low density (Li, Na, K are less dense than water)
. React rapidly with oxygen, chlorine and water
. Form +1 ions eg Na+

Question 2

Transition Metals

Answer 2

Hard and Strong metals eg iron.
High melting points (apart from mercury)
High density
Much less reactive than group 1 metals eg O2, Cl2, and H2O
Can form ions with different charges e.g. Fe2+, Fe3+, Ni2+, Ni4+
Form colored compounds
Can be used as catalysts
