Question

Li has chemical properties most similar to :

• A. Al
• B. Ca
• C. Mg
• D. Ti

Answer 1

Answer: (C)

Mg

Li has chemical properties most similar to Mg due to diagonal relationship.
Both exhibits same properties like
(i).

$MgC{O}_3\stackrel{\Delta }{\to }MgO+C{O}_2$
$L{i}_{2}C{O}_3\stackrel{\Delta }{\to }L{i}_{2}O+C{O}_2$

(ii).

$3Mg+N_2\to M{g}_3{N}_2$

$6Li+N_2\to 2L{i}_{3}N$

Hence option C is correct answer.
