Ans : The general electronic configuration of this block is ns2np1-6, but it differs for the elements inside.
- Unlike the other groups, metals, metalloids, and non-metalloids are present here. Non-metallic nature reduces on moving down.
- Boron, the first element, shows anomalous properties like high melting and boiling points, absence of d-orbitals, notion metallic nature and more.
- The oxidation state increases on moving towards right from left.
- The inert pair effect is shown by elements.
