(a) A cube of osmium metal 1.500 cm on a side has a mass of 76.31 g at 25 °C. What is its density in g>cm3 at this tempera-
ture? (b) The density of titanium metal is 4.51g>cm3 at 25 °C.

What mass of titanium displaces 125.0 mL of water at 25 °C?

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
