An element X has mass number 35 and the number of neutrons, is 18. I mean how cool is it that with the change in a mass number of just 2 you go from Carbon (whose mass number is 6) to Oxygen (whose mass number is 8)? With two beyond tiny particles you can have two totally different elements! ![]() I am a huge science nerd (and this will just prove it) but I loved the mass numbers of atoms because of the order it gave to all of these completely different elements. Rewards for good behavior have changed a bit from getting to clean the board and go run errands for teachers hasn't it? The mole (abbreviated mol) is the SI measure of quantity of a chemical entity, such as atoms, electrons, or protons. Maybe as a reinforcing reward, for the child that gets the best grade on the day's work, then maybe they can pick a YouTube or other online video to show the class. They actually have a period table of the elements song on YouTube (which of course begs the question - what don't they have on YouTube!)ĭepending on budget constraints and what-not you could do some experiments involving the periodic table and those you can also find how-to's on the internet. So, we know in our atom of silicon-30, there must be. I do not have a suggestion for mass numbers but a great way to wake kids up a bit can be with song. Silicon is the element just below carbon in the periodic table with an atomic number of 14. August 9, - You are probably right - unfortunately your own enthusiasm does not always translate to excitement from students (but it does not hurt either).
