The main difference between polar molecules and nonpolar molecules lies in the arrangement of atoms in the molecule. Additionally, polar molecules have an electrical field charge, while nonpolar molecules do not possess ... More »

In nonpolar covalent bonds, electrons are shared equally by both members of the bond, but they are shared unequally in polar covalent bonds. Polar covalent bonds occur when there is a difference in electronegativity, or ... More »

Classification of a bond as polar, nonpolar or ionic depends on its electronegativity difference. The electronegativity difference is obtained by calculating the difference between the electronegativity values of the ato... More » Science Chemistry Solutions & Mixtures

The difference between an atom and a molecule is that molecules are composed of two or more atoms. Atoms are the smallest units of matter and, when they join chemically, they form a molecule. More » Science Chemistry Atoms & Molecules

The molecular formula describes the number and type of atoms in a single molecule of a substance, while the empirical formula is a simplified version that represents the ratios of the substance's atoms. Since the molecul... More »

A molecule is a group of two or more atoms bonded together, while a compound is a group of two or more atoms bonded together where the atoms are from at least two types of elements. All compounds are also molecules, but ... More »

Atoms and molecules both make up matter in the universe, but atoms make up molecules. In order to form molecules, atoms form bonds. More » Science Chemistry Atoms & Molecules
