Is lithium likely to form an ionic compound with strontium?

No, lithium and strontium are both metals. Ionic compounds occur between metals and non-metals. They are both positively charged, so an ionic bond would not be attainable.

What is strontium?

StrontiumStrontium, element number 38, is an Alkaline Earth metal from Group 2 of the periodic table. It has a +2 electronegativity (like all the Group 2 elements) and is highly reactive. As such, it cannot be found free in nature. Its name derives from the Scottish village Strontian, and it was near this small community that minerals from which strontium was first isolated came.

Strontium is used as an X-ray supressor in the glass of the color cathode ray tube (CRT) in color TVs and video displays. (Note that the CRT is waning in popularity as technology advances.) It also has other applications in the manufacture of alloys, some of which are eutectic. Salts of this metal are used in pyrotechnics and flares to impart a specific color to the flame. The metal has four stable isotopes, but also has a number of radioisotopes that find a variety of applications in nuclear pharmacology. And the value of these radioactive isotopes of strontium also extends to uses in both medical and other biological research, and as a heat source in the manufacture of thermoelectric generators.
