both form nitrides

B

nitrates of both Li and Mg yield `NO_(2)` and `O_(2)` on heating

C

both form basic carbonates

D

both form soluble bicarbonates

Text Solution

Verified by Experts

The correct Answer is:
C
Li does not form basic carbonates but Mg does such as 3 Mg `CO_(3).Mg(OH)_(2). 3 H_(2)O` .
