It decreases as you go left to right on the periodic table because of the greater amount of protons. The rules for deciding which element has a larger atomic radius are the following: The atomic radius for each individual element is defined as a measure of the size of each individual atom, normally the mean (average) or the distance from the middle of the nucleus to the boundary of the neighboring cloud of electrons. We know when we look at the periodic table that there are rows (horizontal) and there are columns (vertical).įor this problem, we are locating elements and determining their atomic radius to see which is larger of the elements chosen. To complete this problem there are a few rules and guidelines you will need to know about before starting.įirstly, we need to be able to locate each element in comparison to the other on our periodic table of elements. To complete this type of problem you will need a periodic table of elements handy to easily access each element to be able to tell where it is located in comparison to other elements.

In other words, oxygen more strongly attracts electrons when in a bond with hydrogen. Electronegativity is a property inherent to the atom in question, whereas dipole moment is a property of the bond between them.įor example, oxygen has an electronegativity of 3.44, and hydrogen of 2.20. Dipole moment, however, is dependent on the electronegativity of the atoms making up the bond. When comparing more than one polar covalent molecule, we use the dipole moment value to help us determine relative strength of polarity. The former is purely ionic, and the latter is polar covalent. An example can be seen by contrasting sodium chloride, NaCl, with an organic molecule, R-C-OH. Polar compounds are different from those compounds that are purely nonpolar or purely ionic. Electronegativity is an important concept in physical chemistry, and often used to help quantify the dipole moment of polar compounds.
