Question

chemical formula co
electrons needed 8/2 for each atom
electrons available add up group #s
electrons shared needed minus available

of bonds shared divided by 2

electron dot diagram

Explanation:

Step1: Calculate electrons needed

Carbon (C) needs 8 electrons and oxygen (O) needs 8 electrons, so total electrons needed is $8 + 8=16$.

Step2: Calculate electrons available

Carbon is in group 4 and oxygen is in group 6. So electrons available is $4 + 6 = 10$.

Step3: Calculate electrons shared

Electrons shared = electrons needed - electrons available, so $16-10 = 6$.

Step4: Calculate number of bonds

Number of bonds = electrons shared $\div$ 2, so $6\div2=3$.

Step5: Draw electron - dot diagram

The electron - dot diagram for CO has a triple bond between C and O, with two lone - pairs on O and one lone - pair on C.

Answer:

Electrons Needed: 16
Electrons Available: 10
Electrons Shared: 6

of Bonds: 3
