Problem: In the Lewis structure shown here, A, D, E, Q, X, and Z represent elements in the first two rows of the periodic table (H - Ne).Identify Q so that its formal charge is zero.

FREE Expert Solution

Formal Charge is the charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity.


The steps that have to be taken to solve this problem are:

  1. Use the formal charge equation to find the group number.
  2. Note that the formal charge around Q is zero.

Problem Details
In the Lewis structure shown here, A, D, E, Q, X, and Z represent elements in the first two rows of the periodic table (H - Ne).

D is single bonded left to A (three pairs of dots), double bonded above to E (two pairs of dots), and single bonded right to Q. Q, which has one pair of dots, is single bonded above to X and single bonded right to Z.

Identify Q so that its formal charge is zero.
