Atomic number, atomic mass, protons, neutrons and electrons: from fizzics.org
Atomic number and atomic mass together provide key information about an isotope of an element. The two numbers prefix the symbol, the one above giving the atomic mass and the one below the atomic number. The atomic number or proton number defines which element it is. By subtracting that fr

Molecular Formula | Chemistry | Homework Help
The Molecular Formula tells you the number of atoms of each of the elements in one molecule of a compound. In a previous video, we found the Empirical Formula, and this is a related idea, but not the same thing. The Empirical Formula gives the lowest whole number ratio of the atoms of the

GCSE Science Revision Chemistry "Calculating Moles of a Compound"
Find my revision workbooks here: https://www.freesciencelessons.co.uk/workbooks In this video, we continue looking at the idea of moles. We learn how to use the relative formula mass to calculate the number of moles of a compound. You'll need this later, so it's really important stuff.
