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.

Non-tropic hormones behave in an opposite manner to tropic hormones. They act on target cells rather than on the endocrine glands. Non-tropic hormones are those that act directly on targeted tissues or cells, and not on other endocrine gland to stimulate release of other hormones. 1  Many hormones act in a chain reaction. Tropic hormones usually act in the beginning of the reaction stimulating other endocrine gland to eventually release non-tropic hormones. These are the ones that act in the end of the chain reaction on other cells that are not part of other endocrine gland.
