Q

What compounds do Group 1 elements form?

A
  • Group 1 form colourless compounds (OFTEN WHITE)
16
Q

Does Cu (II) SO₄form the same coloured compound as Cu₂(SO₄)₃

A
  • No. Cu(II) has a different charge to Cu(III) so they will form different coloured compounds.
17
Q

What 3 transition metals are magnetic?

A

1.) Cobalt
2.) Iron
3.) Nickel

18
Q

True or False. Most transition metals ARE magnetic.

A

False. Mosr ARE NOT magnetic.

19
Q

Give 2 examples of transition metals that only form one type of ion.

A

Ag –> Ag⁺
Zn—> Zn²⁺

20
Q

Give 4 chemical properties of Transition metals.

A
  • Low reactivity
  • Catalysts
  • Various oxidation states
  • Coloures compounds
21
Q

What are metals vs non- metals?

A
  • Metals: Elements that react to form positive ions.
  • Non- metals: Elements that react to form negative ions.
22
Q

What are the differences between transition metals and alkali metals?

A
  • Melting points
  • Densitities
  • Hardness (hard and strong vs soft)
  • Reactions with oxygen, water and halogens. (very rapidly vs MUCH LESS REACTIVE THAN Group 1)
  • Colours of compounds
  • Ions formed
  • Transition used as catalysts, Group 1 aren’t
