In very few limited locations (most of which are European). I'll leave a Related Link to an image of a world map, pointing to locations where Strontium was mined (2005 was the most recent data available, my apologies).
Nearly 100% of all strontium found in nature is not radioactive. There are traces of radioactive strontium-90 found in nature, but only traces. Like all elements, strontium has radioactive synthetic isotopes.
A mineral found near Strontian in Scotland was found to contain a new element in 1790 by A crawford.
The alkaline earth metals are the elements found in group 2 of the periodic table. They include beryllium, magnesium, calcium, strontium, barium, and radium.
1) Strontium bursts into flames when it is exposed to air. 2) It was discovered in Scotland. 3) It's used in fireworks and toothpaste. 4) Strontium is a soft, silvery metal. 5) Strontium titanate is very soft but has an extremely high refractive index and an optical dispersion greater than that of diamond. (It bends and separates light)
Alkaline earth metals
Strontium is one of the most common elements found on earth. It is mainly found in igneous rock, and sedimentary formations.
calcium.simple.
strontium is alkaline earth metal and its oxide is a basic alkaline.

The element with 38 electrons is Strontium (Sr). Strontium is an Alkaline Earth Metal in Period 5 of the Periodic Table. Strontium has 38 electrons, 5 electron shells and 2 electrons in the outer shell.

Astatine is a heavy halogen; no similarities with strontium (alkaline earth metal).
