Describes shape and location of fish fins, but not how each fin type helps a fish move through water, for example, a tail fin acts as rudder and propeller. Canât describe shape or location of fish fins or how each fin type helps a fish move through water.elvic fins, located on the bottom of the fish in front of the anal fin, help balance the fish, keep it level, and prevent it from rolling from side to side. Fish sometimes rest by sitting on their pelvic fins.
The oxidation number of lithium in lithium nitrate is 1. Formula: LiNO3. Hill system formula: Li1N1O3. CAS registry number: [7790-69-4] Formula weight: 68.946. Class: nitrate. Colour: white. Appearance: crystalline solid.
Lithium always has 3 protons: its atomic number is 3, and this is decided BY its amount of protons (or by its nucleus' charge if you want to get more technical). Therefore, a lithium atom with neutral charge will have 3 electrons, too. 92.5% of naturally occurring lithium atoms are Li7, which has 4 neutrons. The only other stable isotope of lithium is Li6, which has 3 neutrons. This makes up for most of the rest of natural occurring lithium.
