Question

In the test of nitrogen the Prussian blue color formed is of-

Answer 1

We have to remember that the atomic number of the atom is equal to the number of protons or the number of electrons. In every atom the number of protons and the number of electrons are equal. The electrons in the atom are filled by the lower energy level to the higher energy level. In modern periodic table elements are arranged in the table depending on the atomic number. In this way only periods and rows are arranged in the modern periodic table. Organic analysis is important for qualification. In that organic analysis first we focused on the aromatic or non-aromatic compound. If it is aromatic, further study based on that weather benzenoid or non-benzenoid compound. If it is non-aromatic, further study goes to the acyclic or aliphatic compounds. Every compound functional analysis is very important.

Complete answer:
As we know that in chemistry some analysis and test is used to find the atom and compounds in the unknown material.
In that one of the tests is used for the detection of nitrogen groups in the unknown material. In this test, the colour is only the identification of the presence of the nitrogen. In this test, the Prussian blue color is the indication of the presence of the nitrogen. In the test of nitrogen the Prussian blue color formed is of ferric ferrocyanide.
According to the above discussion, we conclude in the test of nitrogen the Prussian blue color formed is of ferric ferrocyanide.

Note:
We need to know that the atomic number of nitrogen is $7$ and the total number of electrons is$7$and the symbol of nitrogen is ${\text{N}}$. In this seven electrons, first two electrons are going to filled in the first energy level $1{s^2}$, remaining five electron are going to filled in the second energy level, in these five electrons two electrons are going to filled in $2{s^2}$ and three electrons are filled each electron in $2p_x^12p_y^12p_z^1$. The number of electrons in the atom is equal to the atomic number of the atom. The electron fills in the atomic orbital of the atom. The electron fill in the atomic orbital is followed by the three important principles. There is the Pauli exclusion principle, Aufbau principle and Hund’s rule.
