    1) Using only the periodic table, arrange each set of atoms in order of increasing radius. Rank from smallest to largest. To rank items as equivalent, overlap them.

    a) Be, Mg, Ca

    b) Ge, Br, Ga

    c) Si, TI, Al

    2) Rank the following elements in order of decreasing atomic radius.Rank from largest to smallest radius. To rank items as equivalent, overlap them.

    a) Cl, I, F, Br
    b) C, B, O, F

    1) Using only the periodic table, arrange each set of atoms in order of increasing radius.Rank from smallest to largest. To rank items as equivalent, overlap them.

    a) Be, Mg, Ca
    Atomic radius increases as you go down the periodic table. This means the order will be Be < Mg < Ca.

    b) Ge, Br, Ga
    Atomic radius increases as you go left across the periodic table. This means the order will be Br < Ge < Ga.

    c) Si, TI, Al
    Ti will be the largest because it is farthest down on the periodic table. Al is larger than Si because it is farther left. The order will be Si < Al < Ti.

    2) Rank the following elements in order of decreasing atomic radius.Rank from largest to smallest radius. To rank items as equivalent, overlap them.

    a) Cl, I, F, Br
    Atomic radius increases as you go down the periodic table. The order will be I > Br > Cl > F.

    b) C, B, O, F

    Atomic radius increases as you go left across the periodic table. The order will be B > C > O > F.
