Most students who come to me already “know the content”. They can talk through bonding, enthalpy or organic mechanisms in a lesson. Then the paper arrives and the grade does...

In chemistry, time and time again it is about understanding the fundamentals:1) Protons, neutrons, electrons - the masses and charges of each.2) How electrons arrange themselves into ...

Understanding Energy Levels in ChemistryEnergy levels are central to modern chemistry, forming the basis for much of what we understand about atomic and molecular structure. These qua...

Redox reaction: The oxidation and reduction takes place simultaneously in a chemical reaction is called redox reaction.Example: Fe2O3 + 3H2 = ; 2Fe + 3H2ODifference between ox...

According to the NIST, a mole (mol) contains "exactly 6.02214076 × 1023 ;elementary entities". But what exactly does this mean? An elementary entity can be any ...

Atom and Sub-atomic particlesAll atoms are made of smaller particles named: protons, neutrons and electrons. Protons and neutrons counted together make the mass number of an atom, and...

When you are baking a cake how do you know how much of each ingredient to use.A balanced chemical equation tells you how much of each reactant that needs to be used to get desired pro...

The way that atoms bond together affects the electrical properties of the materials they form. For example, in materials held together by the metallic bond, electrons float loosely be...
