    Name some characteristics that separate non-metals from metals.
    Compared to metals, non-metals: are poor conductors have a high electronegativity if not gaseous, are generally brittle or waxy as opposed to malleable and lustrous are far more likely to form anions in ionic compounds.

    It decreases.

    It increases.

    How does ionic radius change as you move across a period from left to right?
    First it decreases, then there is a big increase in size, and then it decreases again.

    They increase.

    Why is aluminum's first ionization energy lower than magnesium's, even though this seems to violate the pattern?
    The first electron from aluminum comes from the almost-empty p orbital, while the first electron from magnesium comes from the full s orbital.

    Why is the second ionization energy always higher than the first ionization energy?
    The second ionization is the energy it takes to remove an electron from an already positively charged ion. It is much more difficult to pull an electron from something that is positively charged than it is to pull an electron from something that is neutral.
