Representative periodic table up to Ca with electronic configuration of elements
: 1. The elements present in same group have same number of valence electrons. 2. The total number of electron present in the valence shell of the representative elements indicates its group number. 3. The electrons are added across a period..
Advantages of Long form Periodic Table
1. The classification of elements is based on the atomic number, which is a more fundamental property. 2. The reason for placing isotopes at one place is justified as the classification is on the basis of atomic number. 3. It explains the periodicity of the properties of the ..

With developments on the structure of atoms, it was discovered that the atomic number (Z) is the important characteristic of the atom and not the atomic mass. This led to the development of the modern periodic law by Moseley in 1942. The modern periodic law states that "th..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
The tutors are amazing. They are very committed in helping students solve the questions and explains all the steps beautifully. So 5 stars for Tutor Vista.
