The first energy level in an atom can hold how many atoms?   The first shell of an atom can hold 2 electrons. This does not mean that all atoms do have 2 electrons in their first shell. The exception is hydrogen (atomic number = 1 â¦) which has only 1 electron in its first shell before reacting with other atoms.

Antidiuretic hormone, ADH or vasopressin. The antidiuretic hormone, ADH, also called vasopressin and arginine-vasopressin, is a nanopeptide (nine amino acids) synthesized in the hypothalamus, transported to and stored in the posterior lobe of the pituitary gland which releases it into the blood circulation.It has antidiuretic and vasopressor actions.ormed in the supra-optic and paraventricular nuclei of the hypothalamus by cleavages of a preprohormone of 168 amino acids and then a prohormone, vasopressin is transported to the posterior lobe of the pituitary gland which stores it.
