Objective: Students will be able to calculate an average atomic mass of an element based on isotopic data.

Warm-Up: (Part 1)

1. How many protons does an atom have if it has 31 neutrons and a mass number of 64?  Please identify the element?

2. How many electrons would this atom have if it has a charge of -3?

Warm-Up: (Part 2)

3. An ion with a charge of +2 has 56 protons.  How many electrons does it have?  Please identify the element.

4. If this atom has a mass number of 138, how many neutrons does it have?
