• # question_answer 8) Write the Lewis structures for the following molecules/ions: ${{H}_{2}}S,\,\,SiC{{l}_{4}},\,\,Be{{F}_{2}},\,\,ClO_{3}^{-},\,\,HCOOH$

${{H}_{2}}S$: A = 2 + 6 = 8, N = 2 x 2 + 8 = 12, S = N - A = 12 - 8 = 4 electrons shared $SiC{{l}_{4}}$:$A=4+4\times 7=32,N=8+8\times 4=40,$ $S=N-A=40-32=8$ electrons shared $Be{{F}_{2}}$: $ClO_{3}^{-}$: A = 7 + 6 x 3 + 1 = 26, N = 8 + 3 x 8 = 32, S = N - A = 32 - 26 = 6 electrons shared HCOOH : A = 18, N = 28, S = N - A =28 -18 = 10 electrons shared
