Lithium resembles magnesium in some of its properties. Mention two such properties and give reasons for this resemblance.

Answers (1)

Li and Mg have similar ionic radii due to which some of their properties resemble.

Both Li and Mg react slowly with water. Their oxides and hydroxides are much less soluble, and their hydroxides decompose on heating.

2LiOH \rightarrow Li_{2}O+H_{2}O (On heating)

 2Mg(OH)_{2} \rightarrow Mg_{2}O+2H_{2}O

Both form nitride, Li_{3}N and Mg_{3}N_{2}, by direct combination with nitrogen.

6Li+N_{2}\rightarrow 2Li_{3}N

3Mg+N_{2}\rightarrow 2Mg_{3}N_{2}
