In what ways lithium shows similarities to magnesium in its chemical behavior?

Explanation

In the periodic table the first element of a group in the 2nd period shows similar properties with the second element of the next group in the third period. This relationship is know as diagonal relationship.
Li shows similary with Mg in the following respects.
(a) Lithium is slow to react with water. Mg decomposes water in hot condition.
(b) Both lithium and magnesium give monoxides only.
LiCl is deliquescent like `MgCl_(2)`.
(d) Halides of Lithium and magnesium are soluble in organic solvents.
(e ) Both `Li^(+)` and `Mg^(2+)` ions are highly hydrated.
(f) The carbonates, phosphates and fluorides of both Lithium and Magnesium are sparingly soluble in water.
(g) Lithium alkyls are chemically similar to Grignard reagents in organic synthesis.
