Chemistry Review 🧪

Unit 1 Biology - Basic Chemistry

Compound

Chemical combinations of 2 or more elements with a fixed ratio and different characteristics than their elements.

Atom

The basic unit of matter with the properties of an element, composed of protons, electrons, and neutrons.

Isotopes

Different forms of the same element with the same number of protons but different numbers of neutrons.

Radioactive Isotope

An isotope that undergoes radioactive decay, used in dating fossils and medical tracing.

Energy

The capacity to cause change.

Potential Energy

Energy that matter has due to its position or structure.

Kinetic Energy

Energy of motion.

Electron Configuration

The arrangement of electrons in an atom, influencing its chemical properties and bonding.

Covalent Bond

Sharing of a pair of valence electrons between atoms.

Ionic Bond

Attraction between anions (negatively charged ions) and cations (positively charged ions).

Hydrogen Bonds

Weak bonds formed between a hydrogen atom and an electronegative atom.

Van der Waals Interactions

Weak interactions between molecules due to temporary regions of positive and negative charges.

Chemical Reactions

Processes involving the making and breaking of chemical bonds, leading to changes in matter composition and the conversion of reactants into products.

Chemical Equilibrium

State in a chemical reaction where the forward and reverse reaction rates are equal.
