Question
What are the best steps to follow when drawing a lewis structure? I'm getting conflicting steps when determining the central atom.Do you determine it based on electronegativity or if it's the element there's only one of?

- Decide whether these proposed Lewis structures are reasonable. proposed Lewis structure :C=0: [H_H_O_H]* :F=0=F: Is the proposed Lewis structure reasonable? Yes. No, it has the wrong number of valence electrons. The correct number is: 0 No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* Yes. No, it has the wrong number of valence electrons. The correct number is:0 No, It has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are: 0 O Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* 0 If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many times as necessary. For example, if two oxygen atoms don't satisfy the octet rule, enter "0,0". X Śarrow_forwardWrite the Lewis structure for SO, where the central sulfur atom obeys the octet rule.

AA lone pairs.arrow_forwardQuestion 12 Based on the "best" Lewis structure after applying formal charge considerations, how many non-bonding valence electrons are around the nitrogen atom in the HCN molecule?arrow_forwardAnswer the questions in the table below about the shape of the perchlorate (CIO,) anion. How many electron groups are around the central chlorine atom? Note: one "electron group" means one lone pair, one single bond, one double bond, or one triple bond.
