Show how the glycinate ion h2n–ch2–coo– can act as a bidentate ligand and make a fivemembered ring with a metal ion. [a bi-dentate ligand binds to a metal through two different binding groups.] draw a lewis dot structure of this five membered ring. which atoms in the glycinate ion will bind to a metal ion?

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
