the periods and groups on the periodic table are numbered. for example, the element fluorine (f) is in period 2, group 17. fluorine is a halogen and only needs one more electron to fill its valence (outer) shell. which of the following elements is likely to have properties that are similar to those of fluorine?\n\nlithium (li) in period 2, group 1\n\niron (fe) in period 4, group 8\n\nboron (b) in period 2, group 13\n\nbromine (br) in period 4, group 17

Answer

Brief Explanations:

Elements in the same group of the periodic table have similar chemical properties because they have the same number of valence electrons. Fluorine is in group 17. Bromine is also in group 17, so it is likely to have properties similar to those of fluorine.

Answer:

E. Bromine (Br) in period 4, group 17
