What are p-block elements in periodic table?
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). Helium is not a p-block element, but it is in the noble gas family because it is also a noble gas. Helium is one of the s-block elements.
Which block elements are called p-block elements?
Those elements in which the last electron occupies p-orbitals and are placed together in groups 13, 14, 15, 16, and 17 (Except Helium) are called p-block elements.
What is the general electronic configuration of s-block elements?
The general electronic configuration of s-block elements is [noble gas]ns1 for alkali metals and [noble gas] ns2 for alkaline earth metals.
Where is p-block in periodic table?
The p-block elements are found on the right side of the periodic table. They include the boron, carbon, nitrogen, oxygen and flourine families in addition to the noble gases. The noble gases have full p-orbital’s and are nonreactive.
What is General outer electronic configuration of p-block elements?
The general configuration of p-block elements is ns2np(1−6).
Which of the following represents the general electronic configuration of p-block elements?
1. Which of the following represents the general electronic configuration of an element belonging to the p-block of the periodic table? Explanation: The general configuration representation of p-block elements is (n-2)f0(n-1)d0ns2np1-6.
Which block is present at the extreme right of periodic table?
P block is present at extreme right of periodic table. It has general electronic configuration ns2np1-6. It includes solids, liquids and gases. The elements of this group are metal, non- metal and metalloids.
How many attempts have been made to classify the elements?
Many attempts have been made by many scientists in order to classify elements When the elements were discovered so many patterns were proposed (approx. 2000 patterns ) Initially 31 elements were introduced than the discovery went to 63 then to 114 and now more than it.
What is modern periodic law in chemistry?
Modern periodic law: According to the properties of elements all periodic function of their atomic numbers. So, when elements are arranged according to increasing atomic no.’s there is periodicity in electronic configuration that leads to periodicity in their chemical properties.
What are the elements of the group of elements?
It includes solids, liquids and gases. The elements of this group are metal, non- metal and metalloids. If we move along period in periodic table, non-metallic character increases and if we move down the group, the non-metallic character decreases.
