What is P-block elements Class 11?
What is P-block elements Class 11?
P-Block elements: Contains, metals, non-metals and metalloids. – Boron is a typical non-metal and the other members are metals. – Boron halides are considered to behave like Lewis acids. – Carbon monoxide having lone pair of electrons on C forms metal carbonyls.
What are Germanes and silanes Class 11?
Hydrides of carbon are called hydrocarbons (alkanes, alkenes or alkynes). Hydrides of Si and Ge are known as silanes and germanes. The only hydrides of Sn and Pb are SnH4 (stannane) and PbH4 (plumbane), 5H2O is called bitter of tin and is used as a mordant in dyeing.
How many groups are there in P-block elements in Class 11?
six groups
Consequently there are six groups of p–block elements in the periodic table numbering from 13 to 18.
What are chemical 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.
Why P block elements are 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 D and f-block elements?
The d-block of the periodic table contains the elements of the groups 3-12 in which the d orbitals are progressively filled in each of the four long periods. The f-block consists of elements in which 4 f and 5 f orbitals are progressively filled. They are placed in a separate panel at the bottom of the periodic table.
Why does boiling point increase down Group 14?
The melting and boiling point of carbon, silicon, and germanium is significantly high because they have a very stable solid structure. Sn and Pb have a lower melting point because only two bonds are formed instead of four, due to inert pair effect.
Is Group 14 metal or nonmetal?
Group 14 is the carbon family. The five members are carbon, silicon, germanium, tin, and lead. All of these elements have four electrons in their outermost energy level. Of the Group 14 elements, only carbon and silicon form bonds as nonmetals (sharing electrons covalently).
Is p-block difficult?
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. Hope this helps!

What are the p block elements in CBSE Class 11?
CBSE Class 11 and 12 Chemistry Notes : The P-Block Elements 1. Sulphuric acid is a colourless, dense, oily liquid. MX + H 2 SO 4 → 2HX + M 2 SO 4 2. Concentrated sulphuric acid is a strong dehydrating agent. The burning sensation of concentrated H 2 SO 4 on skin. 3. Hot concentrated sulphuric acid
Which is the maximum oxidation state of p block elements?
The oxidation state of elements in p – block is maximum when it is equal to a total number of valence electrons i.e. the sum of S and P electrons. One of the most interesting facts about the p-block elements is that it contains both non-metals and metalloids. The first member of the p block elements differ…
Which is the external configuration of a p block element?
The general electronic external configuration for p block components is ns2np (1−6). (n−1)d (1−10)ns (0−2) is the general electronic outer configuration of d block components. The general electronic outer F block element configuration is (n−2)f (0−14) (n−1)d (0−1)ns2.
