Atomic Number
The number of protons or the number of electrons in an atom in its normal state is called the atomic number and is denoted by Z. The nucleus of every element contains Z protons and some number of neutrons. The electrons, having the same ch..
Atomic number
This is the number of protons present in the nucleus or the number of electrons present outside the nucleus. It is denoted by the letter Z. Atomic number (Z) = Nuclear charge or number of protons (p) = Number of electrons ..
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 (Fig. 2.1..
The distance from the centre of the nucleus to the outermost shell of an atom is called the atomic radius of that atom (Fig. 2.1..Atomic Structure and Charges
The existence of negative and positive charges on these materials can be explained on the basis of the structure of the atom. Almost all the mass of an atom resides in a central nucleus which contains a number of tightly packed protons and neutron..

Dalton's Atomic Theory
John Dalton provided a simple theory of matter to provide theoretical justification to the laws of chemical combinations in 1805. The basic postulates of the theory are: All substances are made up of tiny, indivisible particles called atoms. Atoms of the same element are identic..

Very good, Tutor was clear and guided me through the whole algebra problems
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
Thank you very much for helping to me is very important to have my lessons. Because you manage to take good notes in school thank you Tutor Vista
I think the tutors knew their stuff really well and was very helpful. math was actually something I dread.not anymore ,Thank you Tutor Vista - jennifer,New york
