When thinking about the word resonance, I am mostly familiar with it in regard to chemistry, namely in the comprehension of molecular stability and behavior. In chemistry terms, the idea of resonance describes the situation in which a molecule has numerous Lewis structures that can be drawn which suggests that the true structure is an average or hybrid of these resonance structures. When trying to understand chemical structures containing delocalized electrons, really grasping the idea of resonance is important. When used in a more common sense, resonance is frequently used as an emotional or sympathetic reaction. For example, when something you experienced happens to someone you know, you may resonate with the people during that time. Resonance, however, in science terms is way more detailed and signifies something more significant than a feeling. Since resonance affects molecular stability and characteristics, an understanding of it is necessary to describe atomic bonding and electronic structure.

Polar molecule:

When thinking of polar molecules, my knowledge surrounding them is that they are important to chemistry and can help us understand molecular polarity and intermolecular forces. A polar molecule is one that has a partial positive and partial negative charge due to an uneven distribution of electron density. This occurs because bounded atoms have different electronegativity levels. In a common sense, a polar molecule can be conceptualized as having a positive and negative end, much like a magnet. A water molecular is the most common polar molecule we interact with on a day to day basis. In contrast, polar molecules in chemistry have net dipole moments, which affect intermolecular interactions and solubility. Since polar molecules are important in influencing the physical and chemical properties of substances, an understanding of them is essential for explaining atomic bonding and electronic structure in chemistry.
