Is strontium chemically similar with calcium or rubidium?
Cesium. For non-transition elements such as rubidium, cesium, and strontium, the most chemically similar element to any other element is always one in the same column of the Periodic Table but in an adjacent row. Since strontium is not in the same column as rubidium but cesium is in the same column and an adjacent row, the answer follows. (This rule is sometimes true also for transition elements, but not always: For example, for elements in columns 8, 9, and 10, the most nearly chemically similar element is one in the same row and an adjacent column within this group, rather than one in the same column but an adjacent row.)
What is the formula and name for Rb O?
Rb is rubidium, O is oxygen. They will combine to form Rb2O which is called rubidium oxide.
If 3.0 grams of strontium-90 in a rock sample remained in 1989 approximately how many grams of strontium-90 were present in the original rock example in 1933?
From the fact that Strontium-90 has a half-life of approximately 28 years, the amount remaining in 1933 would be 3.0 x 2^2 = 12.0 g.
