Chemistry Notes for class 12 Chapter 9 Coordination
... This concept was proposed by Sidgwick. In a complex, the EAN of metal atom is equal to the total number of electrons present in it. EAN = Z – ON of metal + 2 * CN (where, Z = atomic number of metal atom ON = oxidation number of metal and CN = coordination number of complex) An ion with central metal ...

What are proteins?
... Proteins are organic compounds. Proteins contain the following elements: carbon, hydrogen, and oxygen, as well as nitrogen. Proteins are made of many units called amino acids. Amino acids are compounds with an amino group (NH2) on one end and a carboxyl group (-COOH) on the other end. There are 20 ...
