![\text{Number of electron pair}=\frac{1}{2}[V+N-C+A]](/tpl/images/0308/3862/9e987.png)
![\text{Number of electrons}=\frac{1}{2}\times [4+4]=4](/tpl/images/0308/3862/b4293.png)
and the electronic and molecular geometry of the molecule will be tetrahedral. Â The bond angle is 
![\text{Number of electrons}=\frac{1}{2}\times [6+2]=4](/tpl/images/0308/3862/2c46b.png)
but it decreases to

Consider a culture medium on which only gram-positive organisms such as staphylococcus aureus colonies can grow due to an elevated nacl level. a yellow halo surrounds the growth, indicating the bacterium fermented a sugar in the medium, decreasing the ph as a result and changing the color of a ph indicator chemical. this type of medium would be referred to as a differential and enrichment culture.
