Tennessine is in Group 7, below astatine at the bottom of the group.
Which prediction about tennessine is best supported by its position in the Periodic Table?
It is more reactive than iodine, because its outer shell is further from the nucleus, so it loses electrons more easily.
It is less reactive than iodine, because its outer shell is further from the nucleus, so it gains an electron less easily.
It is as reactive as iodine, because both atoms have seven outer shell electrons.
It is more reactive than iodine, because it has more protons to attract an extra electron.
