Daily Objective:

Students will be able to describe the structure of an atom and predict the number of subatomic particles in atoms.

Bellwork:

1) Please complete the Science Department: Atomic Structure CFA on Canvas.

2) What is average atomic mass?  How is it different from mass number?

Element X is known to have two dominant isotopes X-131 and X-133.  The percent abundance of X-131 is known to be 24.611% and its mass is 130.998 amu.  If X-133 has a mass of 133.019 amu, what is the average atomic mass of element X?
