In elements 1–86 on the periodic table (at 25 °C), one particular group contains one element that forms a diatomic gas in its elemental state, at least one metalloid, two nonmetal solids that are not metalloids, and one element that is exclusively radioactive.  The group is:A.Group 14.B.Group 15.C.Group 16.D.Group 17.

Which of the following groups consists only of elements that exist as diatomic molecules at room temperature and pressure?Group of answer choicesF, Cl, O, N, IAr, He, H, O, ClP, He, H, Cl, Ne, FBr, N, H, S, OLi, B, I, Br, Kr, N

Elements with atomic number 10, 18, 36, 54 and 86 are all :-light metalsinert gaseshalogens    Alkaline earth metals

. An element with electronic configuration 2,8,4 will be classified asa) metal b) non metal c) metalloid d) Noble gas

The periodic table places elements in various groups or families, according to their physical and chemical properties.Based on their physical and chemical properties, krypton (Kr), iridium (Ir), cesium (Cs), and strontium (Sr) are classified as, respectively,aa transition metal, an alkaline earth metal, an alkali metal, and a noble gas ban alkali metal, a transition metal, a noble gas, and an alkaline earth metalca transition metal, an alkali metal, a noble gas, and an alkaline earth metal da noble gas, a transition metal, an alkali metal, and an alkaline earth metal
