Select the correct location on the image. The orbital diagram shows the valence electrons of sulfur, which has 16 electrons. If the electrons were added to the atom one at a time, which
would be the last electron to occupy an orbital?

Radon-222 or rn-222 has a half-life of 3.82 days. to determine the fraction of an original sample of rn-222 that remains unchanged after 7.646 days, we calculate the amount of rn-222 remaining after 7.646 days and divide it with the original amount. using 1 gram as a basis and using half-life calculation methods, we can determine that  0.249 or 0.25  grams of rn-222 will remain, and thus the fraction remaining is 0.25 or 1/4.
