Question

which statements are true concerning elements in the same group of the periodic table? select all that apply. a. they have similar properties. b. they are all metals or nonmetals, but not both. c. they are either all solids or all liquids or all gases. d. they have the same number of shells of electrons. e. they have the same number of inner core electrons. f. they have the same outer shell electron configuration.

Explanation:

Elements in the same group of the periodic table have similar chemical properties because they have the same number of outer - shell electrons. They can be metals or non - metals or metalloids. They are not necessarily all solids, liquids or gases. The number of inner core electrons and total number of electron shells vary down the group.

Answer:

A. They have similar properties.
F. They have the same outer shell electron configuration.
