Introduction to Group 13 to 18
Introduction - Elements of group 13 to 18 of the periodic table are collectively called 'p' block elements. The general electronic configuration of these elements is ns 2 np 1 - 6 . They involve the filling up of 'p' orbitals of their outermost shells, when their 's' orbitals ar..

Group 13 Elements (Boron Family) - Introduction
Group 13 of the periodic table consists of the elements boron (B), aluminium (Al), gallium (Ga), indium (In) and thallium (Tl). Except boron, which is classified as a non-metal, all other elements of this group are meta..

Trends in Chemical Reactivity of Group 13 Elements
Unlike boron, the other members of the group are metallic and the electropositive character increases as we go down the group. All these elements in their compounds exhibit the oxidation state of + 3 and +1. The important chemical properties of the boron family are discussed bel..
Representative or Main Group Elements
These consist of all 's' and 'p' block elements excluding the noble gases (group 18 elements). The chemical properties of the representative elements are determined by the number of valence electrons in their atoms. The number of valence electrons belonging to the above two blocks are: 's..
Naming Compounds with More Than One Similar Functional Groups
When a molecule contains more than one similar functional groups, then, the word di (for 2), tri (for 3), etc., is added before the secondary suffix, of the functional group. While adding such words, the vowel 'e' of primary suffix is retained. For example: Here, Word roots = bu..

I was very pleased with my sessions the tutors were a great help and helped me through the problems step by step - Molly
The tutor remembered me from last week and noted my improvement. This is simply amazing :)
Unlimited tutoring for 24/7 in all the subjects, It's a great help for my kids.
I have experienced very innovative way of learning, I joined online tutoring at Tutorvista few months back when I was in grade 10, I scored really well in grade 10 and ny parents were really happy.
