- Which of the following describes the element Br? Choose all that apply: a reacts vigorously as a metal; b belongs to a group consisting entirely of gases; c consists of diatomic molecules in the elemental form; d is one of the group of least reactive elements; e reacts vigorously with alkali metals to form salts; e forms a cation with a charge of 1+.arrow_forward2.46 Why are nonmetals important even though they account for only a very small fraction of the elements in the periodic table?arrow_forwardWhat is the name of the element in Group 4A and Period 5?arrow_forward
- Given that the periodic table is an organizational scheme for the elements, what might be some other logical ways in which to group the elements that would provide meaningful chemical information in a periodic table of your own devising?arrow_forward2.42 What is a period in the periodic table? From what does it derive its name?arrow_forwardUsing the periodic table, classify each of the following elements as a metal or a nonmetal, and then further classify each as a main-group (representative) element, transition metal, or inner transition metal:(a) cobalt(b) europium(c) iodine(d) indium(e) lithium(f) oxygen(h) cadmium(i) terbium(j) rheniumarrow_forward
