Question

What are the numbers of groups that belong to p block elements?

Answer 1

We need to know that in total there are four block elements s, p, d, f block elements. Halogens have only one electron less to attain stable electronic configuration. Group $17$ has elements such as fluorine, chlorine, bromine, iodine. Metalloids can be boron, germanium, silicon which is present in p block elements.

Complete answer:
As we know that in p block elements there are a total of six groups. Let’s see the number of groups in p block elements. The first group is IIIA i.e. Boron group, the second group is IVA i.e. Carbon group, the third group is VA i.e. Nitrogen group, the fourth one is VIA i.e. Chalcogens, the fifth group is VIIA i.e. Halogens and the last one that is sixth group which is also known as zero group is group $18$ i.e. Noble gases. P block is the only group of elements having all three categories of elements that is metals, nonmetals and metalloids. The group $18$ is a noble gas group i.e. also known as an inert gas group having stable electronic configuration. And group $17$ i.e. Halogens has only one electron less to attain stable electronic configuration. Group $17$ has elements such as fluorine, chlorine, bromine, iodine etc, these elements are electronegative in nature and have high electron affinity. Metalloids can be boron, germanium, silicon which is present in p block elements.
In p block elements $np$ is a sub shell that is gradually filled up and the valence shell varies from $n{s^2}n{p^1}$ to $n{s^2}n{p^6}$. Generally p block elements form acidic oxide.

Note:
Now we can see the uses of p block elements: A compound of boron i.e, borax is used in pottery and glass making. Boron is also used in the soap and detergent industry. Chlorine is used in disinfectants. Aluminum is used in making utensils, aluminum foils. And lastly carbon is used in many ways and also its allotropic forms are also useful in making many things.
