Question

how to find no of bonds of atoms?

Answer 1

Hey mate here is your answer:-)

There is a simple, four-step calculation that you can perform:

1. count the valence electrons the atoms you are bonding have.  

2. count the number of valence electrons the atoms would like to have for a noble gas’ valence shell. (i.e. eight for everything main group, two for hydrogen.)

3. substract 2.−1., i.e. the first (existing) from the second (desired). This is your number of bonding electrons. Divide by two for bonding electron pairs.

4. substract 1.−3., i.e. the third (bonding) from the first (existing). This is your number of free electrons. Divide by two for lone pairs.

Using a simple example such as sulphur dioxide:

1. 6 (S)+2⋅6 (2O)=18

2. 8 (S)+2⋅8 (2O)=24

3. 24−18=6, i.e. three bonding electron pairs.

4. 18−6=12 i.e. six lone pairs.
