Atomic number vs. mass number?

Question

Already, so you know how how as the atomic number increases the ration between amount on neutrons and protons increases. I was wondering if there is a general formula(not exact) to predict the ratio based on the atomic number.

Answer 1

Not really. The atomic number is simply the number of protons in an atom of that element. The atomic mass number is the average mass of an atom of said element. Because numbers and distributions of different isotopes vary widely throughout the periodic table, and their stabilities are also so variable, atomic mass really doesn't have an even distribution through the table at all.

Answer 2

Not really. Atomic weight is double Atomic number for many elements, but later on, you get lots more neutrons, and I believe this has to do with the strong nuclear force. With the transuranic elemetns, we are just mentioning the longest-lived isotope.

Answer 3

The mass quantity does certainly confer with the sum of the form of protons and neutrons, despite if it could be for one isotope of the element. Carbon has 3 isotopes. The isotopes are C-12, C-thirteen, C-14.
