Difference between relative atomic mass and atomic mass Is atomic mass the same as atomic number? An atom has a mass number of 24 and 13 neutrons. what is the atomic number of this atom? An atom has a mass number of 25 and 13 neutrons. what is the atomic number of this ...
What is the atomic number for europium? What is the relative atomic mass of thallium? What is the atomic number of molybdenum? What is the atomic number of cerium? What is the atomic number for polonium? What is the atomic number of americium?
Each element in theperiodic tableconsists of atoms, and each atom has a unique atomic mass and unique atomic number. The atomic number refers to the number of protons in the atom's nucleus, while atomic mass reflects the sum of the number of protons and neutrons. It is expressed in AMU ...

What is the atomic number of oxygen? What is relative atomic mass? Oxygen has an atomic mass of 16 amu and an atomic number of 8. How many neutrons are present? What is the atomic mass of copernicium? What is darmstadtium's atomic mass? What is the mass (in grams) of SO3 that con...
atomic number = 1 mass number = 2 hydrogen-3 tritium T 1 1 2 atomic number = 1 mass number = 3 Notice that the general system for naming isotopes is the name of the element followed by a "-" followed by the mass number (=protons+neutrons) of that particular isotope, e.g. hydrogen...
The differences in the mass is due to different number of protons, The number of proton is the same as we are speaking of a particular atom, The relative abundance of the isotopes will define the final mass used with dealing with an element. ...
The total number of protons and neutrons added together is called the relative atomic mass. Hydrogen has a relative atomic mass of 1, while helium's relative atomic mass is 4 (because there are two protons and two neutrons inside). In other words, an atom of helium is four times heavier...
