Branches of Chemistry

Inorganic Chemistry: Study of inorganic compounds, such as minerals and salts.
Organic Chemistry: Study of organic compounds, such as carbon-based compounds.
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 that occur within living organisms.

Atoms: The building blocks of matter, consisting of protons, neutrons, and electrons.
Protons: Positively charged particles that reside in the nucleus.
Neutrons: Particles with no charge that reside in the nucleus.
Electrons: Negatively charged particles that orbit the nucleus.

Chemical Bond: A force that holds atoms together.
Covalent Bond: A bond formed by sharing electrons between atoms.
Ionic Bond: A bond formed by the transfer of electrons between atoms.
Hydrogen Bond: A weak bond formed between atoms with a hydrogen atom bonded to a highly electronegative atom.

Chemical Reaction: A process in which one or more substances are converted into new substances.
Reactants: The substances that undergo a chemical change.
Products: The substances formed as a result of a chemical reaction.
Activation Energy: The minimum energy required for a chemical reaction to occur.
