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.
The valence electrons are found on the valence shell, the outermost  shell of an atom.    By using the periodic table and the group numbers, one can find the  number â¦ of valence electrons for elements in groups (vertical  columns) 1-2 and 13-18.wo, two valence electron Oxygen has two valence electrons since it must gain two in order to obtain 8 electrons in its outermost energy level. However, the number of valence â¦ electrons is six--not two. The valence and valence electrons are only the same for metals in Groups 1, 2, and 3.
