- To find the isotope symbol you have to put the mass number on top of number of protons the element has, then put the element's symbol after that.
After finishing with page 7 we moved onto page 10 and learned about "half-lives." A half-life is the period of time it takes for a substance undergoing decay to decrease by half. We then practiced using half-lives to figure out a problem. Then class ended and Mrs. M assigned us page 9 and page 10 #3 for homework.
P.S. HAPPY NEW YEAR ;)
