Draw the Lewis dot structure ofCO_(3)^(2-) ion .

1.	Draw the Lewis dot structure ofCO_(3)^(2-) ion .
Answer» Solution :Solution . Step .1 . Total number of valence electons of ` CO_(3)= 4 + 3 xx6 = 22 (""_(6)C= 2 ,4,""_(8)O= 2, 6)` Step 2 . Total number of electrons to be distributed in ` CO_(3)""^(2-) = 22 + 2 ` (for two units - ve charge) = 24 Step 3. The skeletal sturcture of ` CO_(2)` is `O OVERSET (O) C O` Step 4. Putting one SHARED pair of electrons between each C and O and completing the OCTETS of OXYGEN, we have In this structure, octet of C is not complete. Hence, multiple bonding is required between C and one of the O- atoms, Drawing a double BOND between C and one O-atom serves the purpose `(PR_CHE_01_XI_C04_SLV_004_S02)`
