Determination of Oxidation Number of an Atom
. For example, in NaCl, the oxidation number of sodium is +1 and that of chlorine is 1. In compounds of non-metallic atoms, the atom with high electronegativity is given negative oxidation number. For example, in HCl, the oxidation number of chlorine is -1 because of its high el..
Atomic Size and Atomic Radius
The distance from the centre of the nucleus to the outermost shell of an atom is called the atomic radius of that atom..
Atomic Number and Atomic Mass
The nuclei of atoms is made up of protons and neutrons. These two components of the nucleus are referred to as nucleons. The electrons occupy the space outside the nucleus. Since an atom is electrically neutral, the number of protons in the nucleus is exactly equal to the number..

Atoms and Atomic Structure
Introduction - The evidence of the electrical nature of matter preceeded the first theories about the structure of matter. In 1832, Michael Faraday discovered electrolysis. He gave the first important clue relating electricity to matter and about the electric nature of atoms..
Relation between Mass Number and Atomic Number
Atomic Number (Z) is the number of protons in the nucleus of an atom. It is also equal to the number of electrons since the atom is electrically neutral. Mass Number (A) is the total number of neutrons and protons present in the nucleus of an atom. The p..

Metals constitute about three fourths of all the known elements. They have characteristic properties such as bright luster, high electrical and thermal conductivity, malleability, ductility and high tensile strength. The attractive force, which binds various metal atoms, is called m..

Tutors are AMAZING, and They helped me understand every single part of the problem and because of the way they explained everything, i had no questions to ask. It was a learning experience to remember. :)
This is excellent. They are the best stat teachers in the world. Very knowledgeable. - Jordan
It was extremely helpful and was able to organize the information in easy to understand ways - Faith
Tutor made sure i understood all points by asking if they were clear. Good job tutor thanks Tutorvista.
