What conclusion can be drawn about the relationship between the arrangement of elements on the periodic table and the patterns observed in their priorities?
A. Properties of elements are related to atomic numbers.
B. Properties of elements are related to ductility.
C. Properties of elements are related malleability.
D. Properties of elements are related to luster.
Is the answer A?

    I assume you meant "properties" and not "priorities".
    Actually, I don't like any of the answers. Having said that, I think A is the answer to the question because it is obvious that B, C, and D make no sense what so ever. It is true that the elements are arranged in order of atomic number (and not by order of atomic mass as was done previously) but their properties depend upon their arrangement in the proper COLUMNS.

    The answer is A

    The correct answer is A. Good luck on your grades!

  • Science -

    Ofcoarse the answer will be A because B,C,D describes metal elements
