What is Sr2 chemistry?
Strontium oxide or strontia, SrO, is formed when strontium reacts with oxygen. It also forms from the decomposition of strontium carbonate SrCO3. It is a strongly basic oxide.
Is strontium poisonous?
For most people, strontium uptake will be moderate. The only strontium compound that is considered a danger to human health, even in small quantities, is strontium chromate. The toxic chromium that it contains mainly causes this. Radioactive strontium is much more of a health risk than stable strontium.

What is the electron configuration of SR2 +?
The noble gas shorthand notation is: #[Kr]5s^(2)#. When strontium forms a 2+ ion the 2 outer #5s# electrons are lost so #Sr^(2+)# can be written as: #1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(10)4s^(2)4p^(6)#.
What is the electron configuration of strontium 2 +?
Strontium is atomic number 38 so its electron configuration can be written: #2.8.18.8.2#. In orbital notation this is: #1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(10)4s^(2)4p^(6)5s^(2)#. The noble gas shorthand notation is: #[Kr]5s^(2)#. When strontium forms a 2+ ion the 2 outer #5s# electrons are lost so #Sr^(2+)# can be written as:
How is strontium used in pyrotechnics and flares?
Volatile strontium salts impart a bright red color to flames, and these salts are used in pyrotechnics and in the production of flares. Like calcium and barium, as well as the alkali metals and the divalent lanthanides europium and ytterbium, strontium metal dissolves directly in liquid ammonia to give a dark blue solution of solvated electrons.
