What do potassium and krypton have in common and what are their differences based on their location on the periodic table? potassium (k) and krypton (kr) on in the same period, so they have the same number of electron shells. krypton is more reactive than potassium because it has a full outer shell. potassium (k) and krypton (kr) on in the same period, so they have the same number of electron shells. potassium is more reactive than krypton because it only has one valence electron. potassium (k) and krypton (kr) are in the same group, so they have the same number of valence electrons. they have different numbers of electron shells. potassium (k) and krypton (kr) are in the same group, so they have the same number of valence electrons. potassium is more reactive, because it has less electron shells than krypton.

The earth's moon is unusually large. two popular theories of the moon's origin include the "sister world" hypothesis, which states that the moon formed from the same materials as the earth, near enough to the earth that they fell into orbit around each other. a second theory is the "capture" hypothesis, in which the moon formed elsewhere in the solar system, and the earth's gravity pulled it into its orbit. studies of what the moon is made of indicate that some of its materials had to come from the earth or from the same area of the solar system where the earth had formed. at the same time, the moon does not contain much of the material that makes up the earth's core, so the moon could not have formed from the same materials as the earth. how do the two facts above affect the described theories of the moon's origin? a. they show that scientists will never agree on where the moon came from. b. they show that more experiments on moon formation need to be done. c. they show that no theory accounts for the existence of the moon. d. they show that neither theory is complete and entirely correct.
