p-block. The p-block is on the right side of the standard periodic table and encompasses elements in groups 13 to 18. Helium, though being the first element in group 18, is not included in the p-block.
Why are they called p-block elements?
The s-block and p-block elements are so called because their valence electrons are in an s orbital or p orbital respectively. They are also called Typical Elements to distinguish them from the transition and inner transition series.
Why is Aluminium in p-block?
Group IIIA or 13 of the periodic table consists of six elements-boron, aluminium, gallium, indium, thallium and ununtrium. These are p-block elements as the last differentiating electron enters np orbital. These elements have four electrons in their valency shell and thus are placed in the IVth group.

What do you mean by p-block element?
P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron.
Why are s and p-block elements Colourless?
In case of s - and p - block elements, the ions can have s-p, p-d transitions. These transitions require energy as high as UV radiations, which are not possible through visible light. Hence, s - and p - block elements generally form colourless salts.

Argon is a noble gas. It sits in the column 18 group VIIA of the periodic table. This means that argon must end with a 3p6 in its electron configuration (3rd row, p block, 6th column). The p block is filled with 6 electrons and all noble gases have a filled p orbital.
Which type of compounds are formed by p-block elements?
These elements show the maximum oxidation state equal to the sum of electrons in the outermost shell or valence shell. Most of the elements of the p – block form covalent compounds although some elements form ionic compounds (such as halogens) and coordination compounds as well.
