Study Notes

Covalent bonds involve atoms sharing electrons, creating stable bonds like in water where they are not easily broken apart.
Nonpolar covalent bonds occur when electrons are equally shared, found in molecules like oxygen and hydrocarbons (e.g., fats, oils).
Polar covalent bonds involve unequal sharing of electrons, seen in molecules like water, sugars, and amino acids.
Ionic bonds result from complete electron transfer between atoms, forming positively charged ions (e.g., sodium) and negatively charged ions (e.g., chloride).
Ionic bonds are relatively weak in water and easily dissolve, important for nerve signaling and maintaining osmotic balance in the body.
Hydrogen bonds form between polar molecules with partial charges, stabilizing structures like DNA strands and proteins.
Hydrogen bonds are crucial for physiological functions such as creating water tension in the lungs and stabilizing various structures in the body.
