Math: We learned how to add and subtract fractions with unlike denominators. Homework; finish 9T, show work. Pages 49-50 (2-24even) show work and be sure to simplify.
Science:
How many protons in an element? It's equivalent to the atomic number!
How many electrons in an elements? same amount as protons!
The hard one is neutrons: atomic mass - atomic number = neutrons
Atom quiz tomorrow after we finish short video.
