    What are subatomic particles?

    They are the building blocks of atoms.

    What defines an atom?

    Atoms are the smallest units of elements.

    How do metals differ from non-metals?

    Metals are good conductors, while non-metals are not.

    What are isotopes?

    Atoms of the same element with different numbers of neutrons.

    What are ions?

    Charged particles formed when atoms gain or lose electrons.

    What is an ionic compound?

    A compound formed by the electrostatic attraction between ions.

    What is a covalent molecule?

    A molecule formed by the sharing of electron pairs between atoms.

    How do you identify ionic compounds?

    They typically consist of metals and non-metals.

    What is the Law of Conservation of Mass?

    Mass is neither created nor destroyed in a chemical reaction.

    What happens when you balance a chemical equation?

    The number of atoms for each element remains constant.

    What defines an element?

    Consists of one type of atom.

    What is a molecule?

    Group of two or more atoms bonded together.

    How do compounds differ from molecules?

    Compounds contain at least two different elements.

    What are isotopes?

    Atoms with the same protons but different neutrons.

    How are isotopes named?

    By element symbol and atomic mass with a dash.

    What is the valence shell?

    The outermost electron shell of an atom.

    What are valence electrons?

    Electrons in the outermost shell.

    What does the '2, 8, 8, 2' rule describe?

    The maximum number of electrons in each shell.

    What is a Bohr model?

    A diagram showing electron arrangement in shells.

    What is a Lewis Dot Diagram?

    A representation of valence electrons using dots.
