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
Answer:
a. It will accept one electron to complete its outer shell.
Explanation:
Chlorine is in Group 17, so it has <em>seven valence electrons</em>, one short of a complete outer shell.
Thus, it will accept an electron from sodium to complete its outer shell.
