    Study Notes

    Atomic Structure

    • The level of organization being discussed is the atomic level, which is the most basic unit of matter.

    Chemical Compounds

    • A compound is a substance that contains two or more different elements, chemically bonded together in a fixed ratio.

    Atomic Structure

    • An atom is the smallest unit of a chemical element that still maintains the properties of that element.
    • Atoms are made up of protons, neutrons, and electrons.
    • Protons and neutrons are found in the nucleus (center) of the atom, while electrons orbit around the nucleus.

    Chemical Bonding

    • An ionic bond is a type of chemical bond that forms between two atoms when one or more electrons are transferred from one atom to another, resulting in the formation of ions with opposite charges.
    • Ionic bonds typically form between metal and non-metal atoms.

    Intermolecular Forces

    • A hydrogen bond is a type of intermolecular force that occurs when a hydrogen atom bonded to a highly electronegative atom (such as oxygen, nitrogen, or fluorine) forms a weak bond with another electronegative atom.
    • Hydrogen bonds are relatively weak compared to ionic and covalent bonds, but are important in determining the structure and properties of molecules.
