    A. When elements are arranged in order of increasing atomic mass, there is a recurring pattern to their physical and chemical properties. B. When elements are arranged in order of increasing atomic size, there is a recurring pattern to their physical and chemical properties within a group. C. When elements are alphabetized, there is a periodic pattern to their physical and chemical properties within a period. D. When elements are arranged in order of increasing atomic number, there is a recurring pattern to their physical and chemical properties. **my answer: D. is that right???

    and i found this regarding #1: The periodic law states that if the elements are arranged by atomic number, there will be repeating patterns of the properties of the elements. so is my answer D?

    for this #2, i think it's A (like all the halogens are very flammable while all the noble gases don't react to anything)
