Group II Elements

Topic Content:

Beryllium – ₄ Be → 2, 2

Magnesium – ₁₂ Mg → 2, 8, 2

Calcium – ₂₀ Ca → 2, 8, 8, 2

Group II elements include beryllium, magnesium, calcium, strontium, barium, and radium. Group II elements constitute the second most reactive group of metals. They are alkaline earth metals. They are divalent elementsAn atom, with a valency of two, which thus can form two covalent bonds is called divalent. For example, oxygen (O), magnesium (Mg), etc. have a valency of two. More.

Mg → Mg²⁺ + 2e^–
