Study Notes

Particles of Atoms

Atoms are composed of three main particles: protons, neutrons, and electrons.
Protons carry a positive charge, electrons carry a negative charge, while neutrons have no charge (neutral).

Classifications of Matter

Matter is primarily classified into two categories: substances and mixtures.
Substances have a uniform composition and specific chemical formulas or symbols; they do not vary in composition.
Mixtures have variable compositions and do not have fixed formulas; their components can be separated.

Elements and Compounds

Each element consists of only one type of atom, contributing to the definition of a substance.
Compounds are formed when atoms of two or more different elements chemically bond together.

Chemical Formulas

A chemical formula provides insight into a compound by indicating the types of atoms present and their arrangement in the compound.

Mixtures Comparison

Heterogeneous mixtures are characterized by uneven mixing, making their components easy to separate.
Homogeneous mixtures have a uniform composition, making them more challenging to separate.

Solvent vs. Solute

In a solution, the solvent is the component present in the largest amount, while solutes are all other substances dissolved in the solvent.
