Question

stability properties of p block element is what? ​

Answer 1

Answer:

The valence shell electronic configuration of these elements is ns2np3. The s orbital in these elements is completely filled and p orbitals are half-filled, making their electronic configuration extra stable. Covalent and ionic (in a particular state) radii increase in size down the group.

Explanation:

Answer 2

The p-block elements include elements from groups 13, 14, 15, 16, 17 and 18(noble gases), these are said to be normal elements as all shells apart from the ultimate shall or valence shell have stable electronic configuration, the penultimate shell in these elements unlike the transition elements, thus do not show multiple oxidation states or variable valency as transition elements(groups 3-12) do. Thus they are called normal or representative elements. They include some weak metals, metalloids, non metals and noble gases. A transition from less metallic to non metallic elements is observed in p-block.
