Position of Element in the Periodic Table
The position of an element in the periodic table is generally determined by its electronic configuration e.g. electronic configuration of sodium is 2, 8, 1 i.e., it has three shells and one electron in the outermost she..
Periodic Table and Valency of Elements
Group IA, IIA and IIIA consists of metals of normal elements. They have 1, 2, or 3 valence electrons which they can easily donate to acquire the configuration of nearest noble gas. They become positively charged i.e., cations. ..

Best tutor ever. I can actually understand what to do in fraction and decimal division situations
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
This tutoring impressed me a lot! not only did the tutors helped me with currect lessions i needed help with, but they prepared me for future trig lessons to come and very useful imformation - gabriella
