Comparision of Bonds

A QUICK LOOK AT THE THREE DIFFERENT TYPES OF MOLECULAR BONDS

POLAR, NON-POLAR, IONIC BOND COMPARISON CHART

HOW DO YOU FIND OUT THE TYPE OF BOND

If you’re given two elements, such as carbon and oxygen, how do you tell what type of bond they will form?

step1: Get the electronegativilty number of the elements

Get a periodic table of electronegativity by Pauling Scale.

Example Wikipedia Periodic Table

electronegativity-periodictable

step 2: Work out the difference

Electronegativity of carbon = 2.55
Electronegativity of oxygen = 3.44
Difference = 3.44 – 2.55 = 0.89
Compare the chart below: the bond of carbon and oxygen is Polar – Covalent!
