Step 1:I'll solve this problem following the specified LaTeX and formatting guidelines:
Step 2:: Determine Strontium's Position on the Periodic Table
Strontium (Sr) is an alkaline earth metal located in Group 2 of the periodic table. Alkaline earth metals typically form cations by losing their valence electrons.
Step 3:: Electron Configuration Analysis
Strontium's electron configuration is $$1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{6} 4s^{2}$$.
To achieve a stable electron configuration, strontium will lose its two 4s electrons.
Step 4:: Cation Formation
When strontium loses its two valence electrons, it forms a cation with a charge of $$2^{+}$$.
Step 5:: Ionic Notation
The strontium cation can be written as $$Sr^{2+}$$.
Final Answer
Strontium forms a cation with a charge of 2^{+} by losing two electrons.
