Answer 11

two or more forms of an element with the same #of protons/atomic number

Question 12

what do isotopes of the same element NOT have in common?

Answer 12

mass and number of neutrons

Question 13

what does the number next to an isotope indicate? Ex: Chromium-58

Answer 13

mass

Question 14

how do you tell isotopes apart?

Answer 14

number of neutrons and isotope number

Question 15

how do you calculate AVERAGE atomic mass?
(4 steps)

Answer 15

1. find the percentage abundance of each isotope (number of particles/total number of particles then times 100),
2. find the average mass for each isotope (isotopes total mass/number of particles of that isotope)
3. Multiply the percentage abundance (in decimal form) by the average mass of each isotope
4. Add all isotopes together
