What are s-block elements Class 11?

What are s-block elements Class 11?

S-block comprises 14 elements namely hydrogen (H), lithium (Li), helium (He), sodium (Na), beryllium (Be), potassium (K), magnesium (Mg), rubidium (Rb), calcium (Ca), cesium (Cs), strontium (Sr), francium (Fr), barium (Ba), and radium (Ra).

What are the elements of s and p-block Combinedly called Class 11?

Hence s- and p-blocks elements are known as representative elements.

What are s-block and p-block elements?

1. The elements on the extreme left side of the periodic table are called the s-block elements. The elements on the extreme right side of the periodic table are called the p-block elements.

What is p-block class 11?

The elements in which last electron enters into p-subshell are called as p-block elements. The number of p-orbitals is three and, therefore, the maximum number of electrons that can be accommodated in a set of p-orbitals is six, hence p-block contains six groups.

What is p-block element?

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 are p-block elements called?

Halogens and Noble Gases Collectively, these p-block elements are known as the halogens. They have five electrons in their p orbital and are known for being extremely greedy for electrons. They like to steal electrons from metal elements to become 1- ions.

What are S block elements called?

The alkali metals are so called S block because they form alkalies when they react with water. Alkalies, including sodium hydroxide and potassium hydroxide, are hydroxide compounds of these elements.

What is p-block elements Class 12?

. p- Block lies on the right hand side of the periodic table. It consists of the Boron, Carbon, and Nitrogen, Oxygen, Halogen and Noble gas family. -P – Block elements are also known as the representative elements.

Which are 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 is meant by p-block?

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.
