Okay what is the question :)
IB does this. The IB plans out a students high school courses over at least 2 years. Trust me, I'm in it! Hope that helps!
The atomic number is defined by the number of protons in an element. An element is defined by the number of protons the nucleus contains and doesn't have anything to do with how many isotopes the element has. Carbon always has an atomic number of 6 and uranium always has an atomic number of 92. I GOTCHU BROOOO GET THATS A BUDDY
Either 60:50 or 6:5
because anna has 50 and alissa has ten more than anna so alisa would have 60.
