The boiling point of calcium is abnormally high as compared to barium because

Question

The boiling point of calcium is abnormally high as compared to barium because (A) In calcium d-orbital forms weak metallic bond (B) In calcium p-orbital forms weak metallic bond (C) In calcium d-orbital forms strong metallic bond (D) In calcium s-orbital forms strong metallic bond

Tardigrade Admin · Accepted Answer

The electronic configuration of calcium is 1 s 2 2 s 2 2 p 6 3s 2 3p 6 4s 2 . As such due to empty d-orbital calcium forms strong metallic bond. Hence its boiling point is high.

Q. The boiling point of calcium is abnormally high as compared to barium because

In calcium d-orbital forms weak metallic bond

In calcium p-orbital forms weak metallic bond

In calcium d-orbital forms strong metallic bond

In calcium s-orbital forms strong metallic bond

The electronic configuration of calcium is $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 4 s^{2} .$ As such due to empty d-orbital calcium forms strong metallic bond. Hence its boiling point is high.
