Today in class I learned about the mass of subatomic particles. Protons contain 1 amu, neutrons contain 1 amu, and electrons contain 1/1840 amu( amu stands for atomic mass unit). Protons are a part of the atom that gives an element its identity and mass. Electrons gives it reactivity, and neutrons give an element mass and isotope determination. Isotopes have the same number of protons but a different number of neutrons, and has different atomic masses even though it is the same element. When doing isotomic symbols, the mass number (A) is on top, atomic number (Z) is on bottom and the element symbol (X) is to the right of these number. This is what it looks like ( but its suppose to be centered).

This summary really helps outline the main points of what we learned, but maybe just so the separate information is even more clear, separate the topics into paragraphs or bullet, just an idea! But even still, your post answered my questions about the amu measurement for protons, neutrons, and electrons, so thank you!
ReplyDeleteNo, this is awesome. It really helps explain the differences and purposes for the atomic number and element symbol
ReplyDeleteFirst, let me say that I really just like the overall feel of your blog with the background and colors. Now, with my comment, I agree with Celine that you should probably separate the concepts we learned into different sections just to make your posts a little more clear. But other than that, great blog!
