Three sigma limits refer to a statistical concept where data points outside three standard deviations from the mean are considered unusual or significant. This range covers about 99.7% of the data in a normal distribution, making it a common measure of variability in quality control and process improvement. Identifying points beyond three sigma limits can indicate potential issues or anomalies that may require further investigation or corrective action.
In methyl cation (CH3+), there are three sigma bond orbitals available for overlap with the vacant p orbital. These sigma bond orbitals originate from the three C-H bonds in the methyl group.
NH3 contains three sigma bonds: one between each of the hydrogen atoms and the nitrogen atom. The lone pair on the nitrogen atom does not participate in sigma bonding.
Three bonds. One sigma bond and two pi bonds. A lot of energy tied up in those bonds which is why many explosives are nitrogen containing.
HNNH has 6 sigma bonds. Each nitrogen atom forms two sigma bonds with hydrogen atoms, and the two nitrogen atoms are connected by a single sigma bond.
In a butane molecule each of the carbon forms four sigma bonds .The terminal carbon forms three sigma bonds with hydrogen and one sigma bond with carbon and the rest of the each of the carbon atoms form two sigma bonds with carbon and two sigma bonds with hydrogen .In total there are thirteen butane molecules in a sigma bond
This is 3 standard deviations above and below the mean.
4 Sigma is 66800 defects per million pieces You can check out the number of defective pieces per million & the % accuracy for all Sigma levels in the six sigma conversion chart in the related links section
The number of defects is reduced exponentially.

Look up the Three sigma rule!!
NH3 (ammonia) has three sigma bonds, with each hydrogen forming a single sigma bond with the nitrogen atom.
There are 10 sigma bonds in the nitrate ion (NO3-). Each nitrogen-oxygen bond contributes one sigma bond, and there are three nitrogen-oxygen bonds in the nitrate ion.
NH3 contains three sigma bonds: one between each of the hydrogen atoms and the nitrogen atom. The lone pair on the nitrogen atom does not participate in sigma bonding.

The defect rate for a product has historically been about 1.6%. What are the upper and lower control chart limits for a p-chart, if you wish to use a sample size of 100 and 3-sigma limits?
