Question

Write the similarities between lithium and magnesium

Answer 1

ANSWER

☆ lithium is a strong element that is quite similar to magnesium. Their ions have comparable boiling and melting points.

Answer 2

Answer:

• Lithium and magnesium both form monoxides.

2Mg + O2 → 2MgO

• They both react with nitrogen to form their nitrides respectively.

Li(s) + N2(g) → 2Li3N(s)

• They both react slowly with water. They form oxides and hydroxides which decompose on heating.

Mg(s) + 2H2O(g) → Mg(OH)2(aq) + H2(g)

• Oxides of both the elements do not form super oxides.
• The carbonates of both decompose on heating to form the oxides and carbon-dioxide.

2 Mg(s) + CO2 → 2MgO(s) + C(s)

• Lithium chloride (LiCl) and magnesium chloride (MgCl2) are both soluble in ethanol.
• Both the elements are less stable towards heat.
