The total number of electrons in one molecule of carbon dioxide is
A.
22
B.
44
C.
66
D.
88
Answer :
22
Solution :
$${\text{No}}{\text{.}}\,\,{\text{of}}\,\,{e^ - }\,\,{\text{in}}\,\,C = 6\,\,{\text{and}}\,\,{\text{in}}\,\,O = 8$$
$$\therefore \,\,{\text{Total}}\,\,{\text{no}}{\text{.}}\,\,{\text{of}}\,\,{e^ - }\,\,{\text{in}}\,\,C{O_2} = $$ $$6\, + 8 \times 2 = 22$$
