Polar vs Nonpolar Molecules- Definition, 7 Key Differences, Examples

Polar vs Nonpolar Molecules

Polar Molecules Definition A polar molecule is a chemical substance in which the distribution of electrons between the atoms involved is uneven, resulting in a dipole moment. The term polarity is used to describe the difference in electrical poles of a molecule which then determines how polar the molecule is. The determination of whether or … Read more

Physical vs Chemical Change- Definition, 8 Major Differences, Examples

Physical vs Chemical Change

Physical Change Definition A physical change is a process that changes the physical form of a substance but not its chemical composition. During a physical change, the molecules of a substance are rearranged, but the chemical composition of the substance remains unchanged. A physical change usually involves a change in physical properties like the change … Read more

Natural vs Synthetic Polymers- Definition, 7 Key Differences, Examples

Natural vs Synthetic Polymers

Natural Polymers Definition Natural polymers are natural substances composed of large macromolecules formed by the binding of small molecules called monomers. Natural polymers occur in the form of chemical compounds in biological systems and can be broadly categorized into three groups; polysaccharides, polyamides, and polynucleotides. Polymers are not restricted to monomers of the same chemical … Read more

Elements vs Compounds- Definition, 10 Key Differences, Examples

Elements vs Compounds

Elements Definition Elements are pure substances that consist of a single type of atoms and cannot be broken down into smaller units by chemical means. Elements are basic chemical species that combine with other elements to form complex species like compounds and molecules. Elements are defined by the number of protons in the nucleus, which … Read more
