There are two ways that can be used to name isotopes of an element. This is best illustrated by examples. We'll use the element chlorine for simplicity.
The first example is the more common one. The formula for this notation is E-m where E is the name of the element and m is the mass number.
(1) Chlorine-35
(2) Chlorine-37
(3) Chlorine 38
Another is less commonly used. The formula for this notation is m^ a L where m is the mass number, a is the atomic number and L is the first letter of the element.
(1) 35^ 35 Cl
(2) 37^ 35 Cl
(3) 38^ 35 Cl
The difference between sharks and bony fish is that sharks have skeletons made up of cartilage and dont have bones, while bony fish have bones
Statistical data relating to the population and particular groups within it.
The difference between a dominant trait and a recessive trait is that the dominant trait must have one copy of each from two different parent
Example: Brown Hair=H
Light hair=h
Hh is dominant because this is of a copy of each from two parents
A recessive trait must have two same copies coming from the same two parents
Example: HH
