The nucleon numbers 35 and 12 represent the relative isotopic mass of the isotopes. So, chlorine-35 is about three times heavier compared to carbon-12. You can see all the (average) atomic masses of the elements in the Periodic Table.
What else can I help you with?
Why is the atomic mass scale also called the relative atomic mass scale?
All atomic masses are determined by comparing them to the mass of an atom of carbon12. One atomic mass unit equals one twelfth the mass of an atom of carbon12. That's why its called relativeatomic mass.
How the relative atomic mass is related to gram?
relative atomic mass
What is relative atomic mass of magnesium?
The relative atomic mass of magnesium is approximately 24.305.
What is the relative atomic mass of Helium?
Approximately 4.01
How do you find relative atomic mas?
Relative atomic mass is determined by comparing the mass of an atom to one-twelfth of the mass of a carbon-12 atom, which is defined as exactly 12 atomic mass units (amu). To find it, you can use a mass spectrometer to measure the isotopic masses and their relative abundances, then calculate a weighted average based on these values. The formula used is: relative atomic mass = (isotopic mass × relative abundance) / total relative abundance for all isotopes. This gives a value that reflects the average mass of an atom of an element as found in nature.

Why is mass not relative?
Mass IS relative to the speed you are going.
How many years would it take for the mass of a 1.00 g sample of carbon12 to be reduce to 0.125g?
It will take practically forever. Carbon-12 is not radioactive.

What are the charges and relative masses of the main subatomic particles?
electron = relative charge = 1- relative mass = 1/1840 proton = relative charge = 1+ relative mass = 1 neutron = relative charge = 0 relative mass = 1
Mass number is?
It is a measure which gives the relative mass of an element (or compound) - relative to 12C having a mass of 12.
What is the relative atomic mass of potassium?
the relative atomic mass for the element potassium is 39.0983
What is the relative formula mass of copper?
The relative atomic mass of copper is approximately 63.55. To calculate the relative formula mass of copper, you sum the atomic masses of its atoms, which in this case would just be the atomic mass of copper. Therefore, the relative formula mass of copper would be 63.55.
What is the relative atomic mass of Helium?
Approximately 4.01
What is relative atomic mass of magnesium?
The relative atomic mass of magnesium is approximately 24.305.
What is the relative formula mass of iodine?
The relative formula mass of iodine is 253.8 g/mol.
