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.

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
Why Cu has a relative atomic mass?
All elements have an atomic mass relative to 12C having a mass of 12.
How many electrons does silicon-28 have?
Silicon atoms, atomic number 14, have 14 protons in the nucleus. The neutral atom then has 14 electrons. Silicon 28 the most common isotope of silicon has 14 neutrons in the nucleus giving a mass number of 28. The atomic mass of silicon 28 relative to carbon12=12. is 27.9769265325(19)
What is molecular mass?
the relative molecular mass or molecular weight of a compound is the mass of a molecule of the compound relative to the mass of a carbon atom taken as exactly 12.

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 is the relative formula mass for MgCO3?
relative formula mass of MgCO3
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.
Why Cu has a relative atomic mass?
All elements have an atomic mass relative to 12C having a mass of 12.
Which planet has the greatest mass relative to earth?
Jupiter has the greatest mass relative to Earth.
What is the relative atomic mass of potassium?
the relative atomic mass for the element potassium is 39.0983
