test


Which has a higher density, Hg 13.6 g/cm^3,
i,- i,- i,- i,- i,- i,- i,-




or Pt 2.5 * 10^-2 mg/ml?
i,- i,- i,- i,- i,- i,-i,- i,- Hg


Why does Hg 13.6 g/cm^3 have a higher density than Pt 2.5 *
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



10^-2 mg/ml? Because 1 mL=1cm^3; using conversion
i,- i,-i,- i,- i,- i,- i,- i,- i,-



factors one can find that 3600mg/ml > 2.25*10^-2 mg/ml

,As you move from top to bottom on the periodic table, what
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



happens to the first ionization energy of an element?
i,- i,- i,- i,- i,- i,- i,- i,- i,-i,- i,-



Ionization energy trends increase going to the right and to the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



top of the periodic table. Thus going down a group, the energy
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



gets smaller. This is because the contents of elements grow less
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



compact as they get larger, and the attraction goes down.
