- 6Average Atomic MassWeighted Average of all the naturally occurring isotope
- 7IsotopesWhen you have 2 atoms that have same number of protons, but different number of neutrons
- 8—Bohrs Model
- 9Which element is the most stable?C-12, C-13, C-14
Answer: C-12 - 10Mass of 40 is 30% Mass of 42 is 70%.30 times 40=12
.70 times 42=29.4
12+29.4=41.4 g - 11Most Reactive metalsGroup 1 (Alkalie Metals)
