What are the properties of p-block elements?
Properties of P-Block Metals P-block metals have classic metal characteristics: they are shiny, they are good conductors of heat and electricity, and they lose electrons easily. Generally, these metals have high melting points and readily react with nonmetals to form ionic compounds.
What is p-block elements Class 12?
The p-Block elements can be found on the right-hand side of the periodic table and include elements like boron, nitrogen, fluorine, oxygen, nitrogen families, etc. along with noble gases, excluding helium.

Is p-block easy chapter?
P block is a very scoring chapter. If you will give around 7-8 hours in these 3 days to these chapters only, then you might be able to complete it. On 1st day, you can study all the across and up to down rules and then start attempting the previous year questions.
What are p-block elements called?
The ‘s’ and ‘p’ blocks elements called representative elements.
What does the p-block mean?
p-block elements are those in which the last electron occupies p-orbitals and are found in groups 13, 14, 15, 16, and 17 (except helium). Because p-block orbitals can only hold a maximum of six electrons, p-block elements are classified into six groups.
What is p-block element?
P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
How do you remember the p-block elements?
To remember the trend, first arrange the elements in the order in which they are present in the group: B, Al, Ga, In, Tl. Next, switch the places of Ga and Tl – and you get the correct order of the melting point. There are different types of silicates and remembering them is important.
What is the importance of p-block?
It is home to the biggest variety of elements and is the only block that contains all three types of elements: metals, nonmetals and metalloids. There are elements in the p-block that are the most essential to life, that are the most abundant within earth’s crust, and elements that have just barely been discovered.
How do you remember p-block chapters?
- Focus on p- block elements chapters of NCERT class 11 and 12 chemistry textbook.
- Read the chapters at least once.
- Try to read again but this time try to understand meaning and important points.
- After this study the important points, keeping in mind their structures, tabulations, properties, uses etc.
