You can always find the relative mass of an element by adding the number of protons to the number of neutrons for the specific isotope of the element you’re considering. For example, a carbon-12 atom has 6 protons and 6 neutrons, and so has a relative atomic mass of 12. Note that w...
You should find the relative atomic mass of the given element. This type of atomic mass is the average mass of a sample of all its isotopes. This information is waiting for you in the periodic table. You require locating the element there and finding the desired number underneath the symbol...
The isotopic mass is referred as mass of the most abundant isotope of an element. The relative isotopic mass of an isotope mass of one atom of the isotope = 12 x mass of one atom of 12C

The atomic mass number of each element appears under its symbol in the periodic table. It's listed in atomic mass units, which is equivalent to grams/mole.
How to Find the Period of an Element? The value of n for the outermost or valence shell is shown by the period. The number of shells in an atom determines the period. The period of an element is represented by the principal quantum number (n) of the valence electrons in the electronic...
