    Study Notes

    Atomic Structure Basics

    • Atoms are the fundamental building blocks of all matter.
    • Everything, from objects to living things, is composed of atoms.
    • Atoms consist of three main particles: protons, neutrons, and electrons.

    Subatomic Particles

    • Protons: Positively charged particles located in the nucleus (center) of the atom.
    • Electrons: Negatively charged particles found outside the nucleus, orbiting in undefined paths.
    • Neutrons: Neutral particles (no charge) located in the nucleus. They contribute to the atom's mass.

    Atomic Nucleus

    • The nucleus contains protons and neutrons.
    • The nucleus is the central part of the atom.

    Electron Orbitals

    • Electrons are not in fixed, circular orbits, but are instead found in an electron cloud around the nucleus. Simplified diagrams often show electrons orbiting in rings for clarity.
    • The space between the nucleus and the electrons is essentially empty space.

    Atomic Number and Mass

    • The atomic number is the number of protons in an atom. It's a whole number located on the top of an element's box on the periodic table.
    • A neutral atom has the same number of protons and electrons.
    • Atomic mass is the total number of protons and neutrons in an atom (represented by the decimal number on an element’s periodic table box).
    • To calculate the number of neutrons, subtract the number of protons from the atomic mass.

    Periodic Table of Elements

    • The periodic table displays all known elements.
    • The arrangement of elements on the periodic table is based on their atomic numbers.
    • The properties of elements are related to their positions on the table.
    • Various combinations of elements form different compounds from the mundane to the complex, including those found in nature and in man-made objects.

    Isotopes

    • The number of neutrons in an atom can vary. Atoms with the same number of protons but a different number of neutrons are called isotopes.
