DO NOT ANSWER IF YOU DO NOT KNOW THE CORRECT ANSWER! To draw a Lewis structure for a covalent compound, begin by calculating A, the available electrons, and N, the needed electrons.

What is N for the silicon tetrachloride, SiCl4

It is also a type in question so no choices I can show.

m=9

step-by-step explanation:

7m+8=71 subtract   8 from 71 which is 63 than divide it by 7m   equal 9.

                             

Less stable  hope this
