The Autonomic Nervous System. The autonomic nervous system, or ANS, is the portion of the nervous system that regulates involuntary processes. In other words, these are processes that are not under conscious control. The ANS is divided into two divisions: the parasympathetic and the sympathetic nervous systems.The sympathetic nervous system, also called 'fight-or-flight' activation, is the segment that prepares the body for emergency situations.he ANS is divided into two divisions: the parasympathetic and the sympathetic nervous systems.

Hydrogen is a non-metal when it occurs naturally. It can take the form of Hydride when it gains an electron, however we will normally see hydrogen used as H2 (hydrogen gas). If hydrogen is part of a molecule it can be ionic or covalent. The thing here is that for a bond to be ionic the electron shared must be completely taken away or possessed by an atom. If you think about it logically, an ion is a charged atom.
Several of the nonmetals are gases in their elemental form. Elemental hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), and chlorine (Cl, element 17) are all gases at room temperature, and are found as diatomic molecules (H 2, N 2, O 2, F 2, Cl 2).
