Question

What are the characteristics of p- block elements?

Answer 1

p – block elements is the block consisting of a group from $13 - 18$. p- Block lies on the right hand side of the periodic table. It consists of the Boron, Carbon, and Nitrogen, Oxygen, Halogen and Noble gas family.

Complete answer: p – block elements are those elements in which the last valence electrons enter into the p- subshell of the atom. They have the general electronic configuration of $n{s^2}n{p^{1 - 6}}$ .
-P – Block elements are also known as the representative elements. The last group or column of the p– block elements of the periodic table i.e. Noble gases have completely filled p – orbitals, so they are the unreactive elements like the helium gas.
-Now let’s peer more into the general characteristic properties of the p- block elements.
-P- Block elements are generally non- metals but they also consist of some metals and metalloids.
-The non-metallic character of the p- block elements increases on going left to right in the periodic table.
-Whereas, their non-metallic character decreases on going down the periodic table.
-Their ionisation enthalpies increase on moving from left to right in the periodic table.
-And their ionisation enthalpies decrease on going top to bottom of the periodic table.

Note:
Let’s also see the oxidising and the reducing nature of the p- block elements. The oxidising nature of the elements increases on going from left to right in the periodic table, whereas while moving from top to bottom in the periodic table, the reducing nature of the p- block elements increase.
