Answer:
Atomic Mass
Explanation:
it is also sometimes below the symbol of the element :)
Answer: Option (A) is the correct answer.
Explanation:
Atomic mass is defined as the summation of total number of protons and neutrons present in an element.
For example, in [tex]^{12}C[/tex] the number 12 represents the total number of protons and neutrons present in it.
As it is known that an atom of carbon always contains 6 protons but it can hold different number of neutrons.
Hence, in [tex]^{12}C[/tex] the number 12 represents the atomic mass.
Therefore, we can conclude that the number to the right of an element's symbol (ex. C-12) identifies the atomic mass.
