Question

an element has a metallic gray appearance. it also has the properties of both a metal and a nonmetal. in which section of the periodic table indicated above would the element most likely be found?

Answer 1

If it has properties of metal and non metal it is considered a metalloid there are very few spots in which metalloids are located the spots I circled on a blank periodic tables are where the metalloids are located on an actual periodic table your only options are
boron(B) silicon(si) germanium(Ge) arsenic(As)antimony(Sb)tellurium(Te)astatine(At)those are the only places on the periodic table that has metalloids... I hope this helps
