Group of answer choices

atoms that can fit more than 8 electrons

atoms like hydrogen that cannot fit 8 electrons

Potassium, for example, which forms bond with only two electrons in the outer shell

Boron, for example, which can form bonds with only 6 electrons in its outer shell

False, as a substance changes from a solid to a liquid and from a liquid to a gas the molecules get farther apart from each other

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.
