Immunoglobulins are the molecules that intervene in defense against microorganisms, foreign cells and against substances that can cause allergies. They are also known as antibodies. IgM is specific and is the first antibody that appears in primary infections, so its value and quantity is very important to diagnose an infection.
Immunoglobulin M is the first antibody produced on initial exposure to an antigen. It is also known as IgM.
It occurs as a primary response to the antigens against a particular baterium or virus. It is pentavalent in nature and has ten binding sites for antigens.
Therefore, it is concluded that when the body identifies a bacterium or a virus, it releases the antibody IgM.
The electronic structure of Magnesium is 2,8,2 so in order to form a stable ions, it will lose 2 electrons. Now, the proton number of Mg is 12, electron number is 10. It will show positive charge. Conclusion: Mg will lose 2 electrons to form Mg2+.
