    Study Notes

    Acids and Bases

    • pH range for acids is below 7
    • When an acid reacts with a base, salt and water are formed

    Elements and the Periodic Table

    • Atomic number of an element is the number of protons present in the nucleus of an atom
    • As you move from left to right across a period in the periodic table, the atomic radius decreases and the electronegativity increases
    • Noble gases are a group of elements known for having low reactivity and fully filled valence shells
