How do you calculate percent Half Life?
As you can see from this table, the amount of reactant left after n half-lives of a first-order reaction is (1/2)n times the initial concentration….Half-Lives and Radioactive Decay Kinetics.
Number of Half-Lives | Percentage of Reactant Remaining | |
---|---|---|
1 | 100%2=50% | 12(100%)=50% |
2 | 50%2=25% | 12(12)(100%)=25% |
3 | 25%2=12.5% | 12(12)(12)(100%)=12.5% |
n | 100%2n | (12)n(100%)=(12)n% |
What is the exact half life of isotope A?

248Bk | 23.7 h |
260Sg | 4 ms |
How do you find the percentage of radioactive atoms that are left after each half life?

Number of Half-Lives | Percentage of Reactant Remaining | |
---|---|---|
1 | 100%2=50% | 12(100%)=50% |
2 | 50%2=25% | 12(12)(100%)=25% |
3 | 25%2=12.5% | 12(12)(12)(100%)=12.5% |
