What are the important topics in p-block?
Atomic & ionic radii, Ionization enthalpy, Electronegativity, Melting and boiling point, Electron Donor or Acceptor Properties and many other physical properties of p block elements. Metallic character, Oxidation states, covalency and other chemical properties of p block elements.
How many elements are in p-block on the periodic table?
There are 35 p-block elements, all of which are in p orbital with valence electrons.
What are the P-block elements?
Consequently there are six groups of p–block elements in the periodic table numbering from 13 to 18. Boron, carbon, nitrogen, oxygen, fluorine and helium head the groups. Their valence shell electronic configuration is ns2np1-6(except for He). The inner core of the electronic configuration may, however, differ.
What are p-block elements write five characteristic properties of p-block elements?
Answers (1) (i) p-Block elements include both metals and non-metals. (ii) p-Block elements, in most cases, form covalent bonds with other elements. (iii) The ionisation enthalpies are relatively higher than s-block elements. (iv) Some of the p-block elements show variable or more than one oxidation states.
How many questions are asked from P block in JEE?
There are a total of 75 questions from all three subjects and for each subject, 100 marks are allotted. This PDF below consists of the chemistry important questions for Jee Mains.
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.

What is the general electronic configuration of p-block elements?
General electronic configuration of p-block elements: The p-block elements are characterized by the ns2np1-6 valence shell electronic configuration. Representative elements: Elements belonging to the s and p-blocks in the periodic table are called the representative elements or main group elements.
What is the difference between p block and D Block and f-block?
P block covers more portion,d ,f block covers chemical, physical property and variation in bonding energy, enthalpy, redei ,colour, hardness etc.p block compound is very wanted ammonia,phaspheen, sulphuric acid method of prepration etc. There are too many topics just learn about the general properties of p block d block and f block elements.
