Kaizen can be defined as the philosophy and practice of continuous improvement. Kaizen is a workplace methodology. It refers to the practice of looking for ways to improve work processes on a regular basis. The practice involves small, incremental changes rather that large changes.
Phosphate is an anion with the chemical formula #PO_4^(3-)# and has the above configuration. Only single elements have a atomic number, which is the number of protons in the nucleus. The atomic number of phosphorus is 15 and the atomic number of oxygen is 8.
Once one shell is full, the next electron that is added has to move to the next shell. So... for the element of PHOSPHORUS, you already know that the atomic number tells you the number of electrons. That means there are 15 electrons in a Phosphorus atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and five in shell three.
