Usage of strontium salts

    1. The problem statement, all variables and given/known data
    Hello PF!
    I had a lab practice a while ago of using flames to identify elements by its color. It had the first three alkali metals, calcium, magnesium and barium. We didn't use beryllium or strontium for whatever reason.
    I don't know why we didn't use them, and that's why I come here. They are not super toxic, so that's not it. Is it because their salts are too expensive or difficult to obtain, or anything else?
    Does anyone know something?

    Beryllium is highly toxic, especially in elemental form, and the danger is not completely eliminated in compound form.

    Strontium is known to replace calcium in bones, but is not considered toxic unless it is the radioisotope Sr-90.
