Question 3

Nine is the atomic number of fluorine

Question 4

Group is correct

Question 5

True, elements with similar electron configurations are in the same group, so they have similar chemical and physical properties.

Question 6

Question 7

True

Question 8

8, elements with 8 electrons in their outermost shell are stable.
