Answer: The chemical formula of the compound is [tex]Sr_3P_2[/tex]
Explanation:
Strontium is the 38th element of the periodic table. The electronic configuration of this element is [tex][Kr]5s^2[/tex]
This element will loose 2 electrons to attain stable electronic configuration to attain +2 oxidation state.
Phosphorus is the 15th element of the periodic table. The electronic configuration of this element is [tex]1s^22s^22p^63s^22p^3[/tex]
This element requires 3 electron to attain stable electronic configuration to attain -3 oxidation state.
So, by criss-cross method, the oxidation state of the ions are exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
Hence, the chemical formula of the compound is [tex]Sr_3P_2[/tex]
