1 Dorsal fins are found on the back of the fish. 2  There may be up to three of them. 3  The fish uses this fin for balance in the water and sudden movements. 4  Caudal fins are also known as tail fins.5  This is what we refer to as the fish's tail. 6  Anal fins are on the ventral (bottom) surface of the fish, behind the anus.

The oxidation number for phosphorus is +3: four covalent bonds with oxygen atoms yield +4 and the central charge yields -1. The oxidation numbers of oxygen and hydrogen are -2â¦ and +1 respectively. The oxidation number of the overall ion is -1.
The phosphorus ion P-is highly reactive. In fact, the high bond energy is what powers almost all cellular activity. (See Adenosine TriPhosphate, commonly called ATP.) Pho â¦ sphorus, however, also tends to bond with oxygen, creating less active phosphate radicals (PO4).ts atomic number is 33, and it's atomic weight is 74.92. It is very brittle and crystalline; arsenic changes from a s â¦ olid to a gas when heated.   It is poison.     It's a type of poison that can kill you if taken in large doses or over a period of time if taken in smaller doses.
