How can you predict the density of an element? | Yahoo …
8/9/2011· Calcium is the alkaline earth metal in period 4, barium is the alkaline earth metal in period 6. Since strontium is the alkaline earth metal in period 5, you would expect its density to be somewhere between the other two, probably a little closer to barium than calcium because the increase in atomic radius is less from the fifth period to the sixth than from the fourth to the fifth.
