Problem

For the following bonds assign charges to each atom. Use + and - for ionic compounds and δ+ and δ- for covalent bonds where electrons are not equally shared. If a covalent bond has electrons equally shared, leave it blank.

i. Na - F

ii. Cl - Cl

iii. H - F

iv. C - O

v. K - Cl

Solution

We’re being asked to assign the charges to each atom in each compound given.

We’re going to use + and – for ionic compounds and δ+ and δ- for covalent bonds where electrons are not equally shared.


Let’s first define an ionic and molecular bond:

Ionic Bond

involves the transferring of an electron from one element to another element
positively charged ion + negatively charged ion

metal → usually is the positively charged ion (+)
nonmetal → usually is the negatively charged ion (-)
metal(or polyatomic ion) + nonmetal (or polyatomic ion)


Covalent (or Molecular) Bond

involves the sharing of electron(s) between elements

nonmetal + nonmetal
