Question

Odd man out in sodium,potassium,calcium and iron

Answer 1

Iron

Explanation:

• We are asked to find the odd one out of sodium,potassium,calcium and iron.
• The answer is iron and there are two explanations for this.
• The first is because we know that other iron the rest of them belong to the alkali group with high reducing power.
• Alkali group elements exhibit high metallic properties with high reducing power .They can displace most of the elements in any reaction.
• The other reason could be that sodium ,potassium and calcium has single state of valency whereas iron on the other hand has two stable states of valency .

So by these we conclude that iron is the odd one out.
