Elements that form diatomic molecules, or molecules of two atoms each, are commonly found on the right side of the periodic table.
First, we will get the "n", the number of half lives, it is the elapsed time over the half life. In the problem, the time is measured in days, so we have
6/2 = 3
to get the ending amount of radioactive sample, we have
32g x (1/2)³ = 4 grams of radioactive sample ⇒ the amount left after 6 days
Conducters e.g gold copper silver
