Which of these statements correctly describes the use of formal charge in choosing between possible lewis structures to describe a molecule?

i. formal charge on all the atoms should be zero, or at least the smallest possible value.
ii. he sum of the formal charges on all the atoms should equal the charge on the molecule or ion.
ill. the formal charge on an atom is not affected by the of the atom. nitrogen will containing nitrogen and oxygen, the lewis structures with a charge on the
iv. contribute the most to the description of the bonding.

a. ii and iii only
b. ii and iv only
c. i and iii only
d. iii and iv only
e. i and ii only

e. I and II only

Explanation:

A Lewis structure is refer to as a structural representation of a molecule in which dots are used to represent the positions of electrons around the atoms and lines/dot pairs are used to show the covalent bonds between atoms.  A Lewis structure can be sketched for any given covalently-bonded molecule and coordination compounds. Therefore, in this problem, the correct statements are:

I. Formal charge on all the atoms should be zero, or at least the smallest possible value.

II. The sum of the formal charges on all the atoms should equal the charge on the molecule or ion.

Option e. I and II only

the answer is d.) potassium
