Answer:
The compound represents that calcium chloride is an ionic salt made up of 1 calcium ion and 2 chloride ions.
Explanation:
The given chemical formula [tex]CaCl_2[/tex] is of calcium chloride salt.
The chemical formula represents that 1 atom calcium binds with two atoms of chlorine to form a single molecule of calcium chloride.
It is an ionic salt made up 1 calcium ion and 2 chloride ions.
Calcium has atomic number of 20 and chlorine has atomic number of 17. Calcium will loose 2 electrons to gain noble gas stability whereas chlorine atom will gain 1 electron to gain noble gas stability.
[tex][Ca]=[Ar]4s^2[/tex]
[tex][Ca^{2+}]=1s^22s^2p^63s^23p^6[/tex]
[tex][Cl]=1s^22s^2p^63s^23p^5[/tex]
[tex][Cl^{-}]=1s^22s^2p^63s^23p^6[/tex]
[tex]Ca^{2+}+2Cl^-\rightarrow CaCl_2[/tex]
