Mass Number and Atomic Number. The periodic table lists the elements, each element has a symbol with two numbers. One number is above the symbol and the other number is below the symbol. The mass number is the total number of protons and neutrons. The atomic number is the number of protons in an atom of the element.
- Remember that the mass number (a.k.a atomic mass)- is the number of PROTONS and NEUTRONS in the nucleus of the atoms of that element. - The periodic table gives us the atomic number of each element. For example, Hydrogen has the atomic number of 1 and Oxygen has the atomic number of 8. Just look at the whole number on the periodic table!

They will widen their key vocabulary on this topic and broaden their knowledge of both Science and Chemistry. This worksheet is an excellent introduction to Chemistry, Physics and plenty of other Science topics.
The Law of Conservation of Mass states that in an isolated system, mass cannot be created or destroyed as a result of a chemical reaction. Therefore, the mass of the products in a chemical reaction must match the mass of the original reactants although their state may have changed.
An element has the following natural abundances and isotopic masses: 90.92% abundance with 19.99 amu, 0.26% abundance with 20.99 amu, and 8.82% abundance with 21.99 amu. Calculate the average atomic mass of this element. Click here to see a video of the solution.
