This element’s hydrides are classified as “nido” or (10[1])“arachno” (10[3])by counting skeletal (10[1])electron pairs (10[1])in the Wade–Mingos rules. (10[1])This element (10[1])forms the anti-Markovnikov (10[3])product (10[2])when added across a double bond, (10[1])and is then oxidized (-5[1])with hydrogen (-5[1])peroxide to form alcohols (10[1])in a reaction named “hydro [this (10[1])element].” (10[3]-5[1])The (10[1]-5[3])wurtzite form of this element’s nitride (10[1]-5[1])is harder (10[1])than diamond. (-5[1])A (10[1])canonical (-5[1])Lewis (10[1]-5[2])acid (10[1])is this (10[1])element’s (10[2])trifluoride, (10[1]-5[1])which is planar (10[5]-5[2])since this element (10[1])violates (10[1])the octet (10[1])rule and only (10[1])has (10[1])three (-5[1])valence (10[1])electrons. (10[4]-5[2])For 10 points, what (10[1])metalloid is located above aluminum on the periodic table and has (10[1])atomic (10[1])number five? (10[3])■END■ (10[13]0[2])
