Timothy hay for rabbits is simply the best option when deciding what should make up the bulk of your petâs diet. Dental health The second, and no less important, reason that timothy is a great type of hay you can feed your rabbit is that of dental health.
The halogens (F, Cl, Br etc.) are one electron short of a valence shell octet, and are among the most reactive of the elements (they are colored red in this periodic table). In their chemical reactions halogen atoms achieve a valence shell octet by capturing or borrowing the eighth electron from another atom or molecule.
A: Outer shell electrons are called valence electrons. These electrons dictate whether a particular element readily forms compounds. Valence electrons can be gained, lost or shared in the formation of compounds. Atoms want to fill their outer energy shells. In most cases, atoms would need eight electrons to fill their outer energy shells. Elements that have few electrons in their outer shells, such as the metals, are more likely to give up those electrons to other atoms to form a more stable arrangement. Elements such as the nonmetals have almost the full complement of electrons in their outer levels, so they tend to gain electrons during the formation of compounds.
