The value of the an investment with simple interest after is the interest rate.
A compound interest plan pays interest on interest already earned.
Looking at the first isotope in the chart, Carbon 9 has 9 (protons neutrons).
Remember that the Atomic Number (the bottom number) indicates the number of protons.
The top number is the Mass Number for each isotope.
The interest earned with simple interest is the product of the interest rate, the time since the investment (usually measured in years), and the principal.Only two of the carbon isotopes are stable (C is obviously much more common (99%).All the other Carbon Isotopes are unstable and they degrade into something else.Since protons and neutrons weigh about the same, the atomic mass of ordinary carbon is 6 6 = 12.It is called "Carbon-12," which is abbreviated "C." The fact that the atom has six protons is what makes it carbon.
To understand this process we must first understand a little bit about the atoms themselves and how they get their names.
