The mass number represents the number of nucleons (protons + neutrons) in an atom.
this is the net mass of the atom, the proton number + neutron number
It represent the addition of number of protons and neutrons.Also represent mass of a one mole.
The total number of protons and neutrons
The number of electrons
It represents the mass number.
That is the average atomic mass for Mg.
either mass or protons the top is the atomic number it shows how many protons the bottom number is the atomic mass also the weight
Dalton's symbols are not used in chemistry because it is very difficult to represent in chemistry
The Atomic number which is the number of protons in an atom's nucleus.
mass number of dysprosium = 66 + number of neutrons in a specified isotope The mass number is different for each isotope.
It represents the atomic number and atomic mass. Mass number is the superscript Atomic number is the subscript
the symbol scientists use to represent the atomic mass number is the letter U.
The mass number is the sum of protons and neutrons in the atomic nucleus of a chemical element.
It represents the mass number.
atomic mass
95.94 according to my chemistry textbook...
by using stachio chemistry.....
The mass number represents the total number of protons plus neutrons.
That is the average atomic mass for Mg.
The number next to any isotope represents the mass number
It represents the mass number of that particular isotope.
