Branches of Chemistry

Inorganic Chemistry: Study of inorganic compounds, such as minerals and metals, and their properties.
Organic Chemistry: Study of organic compounds, such as carbon-based compounds, and their properties.
Physical Chemistry: Study of the physical properties and behavior of matter at the molecular and atomic level.
Analytical Chemistry: Study of the analysis and identification of the chemical composition of substances.
Biochemistry: Study of the chemical processes and substances that occur within living organisms.

Protons: Positively charged particles in the nucleus of an atom.
Neutrons: Particles with no charge in the nucleus of an atom.
Electrons: Negatively charged particles that orbit the nucleus of an atom.
Atomic Number: Number of protons in an atom's nucleus, which determines the element.
Mass Number: Sum of protons and neutrons in an atom's nucleus.

Ionic Bond: Bond formed between two atoms that have a large difference in electronegativity, resulting in the transfer of electrons.
Covalent Bond: Bond formed between two atoms that share one or more pairs of electrons.
Polar Covalent Bond: Bond formed between two atoms that have a difference in electronegativity, resulting in a partial transfer of electrons.

Chemical Equation: Representation of a chemical reaction using chemical formulas and symbols.
Reactants: Substances that undergo a chemical change in a reaction.
Products: Substances formed as a result of a chemical reaction.
Activation Energy: Minimum energy required for a chemical reaction to occur.
Catalyst: Substance that speeds up a chemical reaction without being consumed.

Mole: Unit of measurement for the amount of a substance, defined as 6.022 x 10^23 particles.
Molar Mass: Mass of one mole of a substance.
Empirical Formula: Simplest whole number ratio of atoms in a compound.
Molecular Formula: Actual number of atoms in a compound.
