Strontium is a soft silver-white or yellowish metallic element that is highly reactive chemically. The metal turns yellow when exposed to air.
The first ionization energy of strontium is 549.5 kJ/mol. It is the energy required to remove one electron from a strontium atom in the gaseous state to form a strontium ion with a 1+ charge.
In its ground state, an atom of strontium has the electron configuration of [Kr] 5s². The highest energy level is n=5, which corresponds to the outermost electrons in the 5s subshell. Thus, the highest energy level in a ground state strontium atom is 5.
Calcium sulfate is more water soluble than strontium sulfate. In water, calcium sulfate has a solubility of about 0.2 g per 100 mL at room temperature, whereas strontium sulfate has a solubility of about 0.006 g per 100 mL at the same temperature.
The compound name for SrH₂ is strontium hydride. It consists of strontium (Sr), a metal from the alkaline earth group, and hydrogen (H) in a 1:2 ratio. Strontium hydride is typically a solid at room temperature and can be used in various chemical reactions, particularly in the production of other strontium compounds.
It is in a solid state of matter.

It indicates that it consists of one strontium and two chlorine atoms. Also, this means that chlorine is in oxidation state of -1 whereas Strontium is in state of +2.
The first ionization energy of strontium is 549.5 kJ/mol. It is the energy required to remove one electron from a strontium atom in the gaseous state to form a strontium ion with a 1+ charge.
When strontium and bromine react, they form strontium bromide, a salt compound. This reaction involves the transfer of electrons from strontium to bromine, resulting in the formation of ionic bonds between the two elements. Strontium bromide is a white crystalline solid at room temperature.

Uranium don't react with water at room temperature; strontium react with water and the hydroxide Sr(OH)2 is formed.

Well, honey, the oxidation number of strontium in the hydride of strontium is +2. It's like asking if Betty White is a national treasure - the answer is obviously yes. So, in this case, strontium is happily rocking that +2 oxidation number like a boss.
