Both lithium and magnesium display several similar properties due to the diagonal relationship; however, the one which is incorrect is:

Options

  1. ABoth form soluble bicarbonates
  2. BBoth form nitrides
  3. CNitrates of both L i and M g yield N O 2 and O 2 on heating
  4. DBoth form basic carbonate

Correct answer

D. Both form basic carbonate

Step-by-step solution
