calculate EAN OF[CO (NH3)]+3
To calculate average atomic mass from different isotopes of an element, we take into account the relative atomic masses of isotopes and their relative abundance on Earth. The following formula is used to calculate the needful : atomic mass = mass of isotope x percent abundance + mass of isotope x percent abundance / 100 (whole expression divided by 100)
The same way you calculate the atomic mass of other elements.
To calculate the atomic mass of any element, add the no. of protons and neutrons. There sum will be the atomic mass. The mass of electrons is not counted towards the atomic mass.
Thalium is a meta element. Atomic mass of it is 204. Atomic number of it is 81.
atomic # = protons atomic mass - atomic number = neutrons atomic # - charge = electrons

very
The atomic number is the number of protons.
7.4
Thalium is a meta element. Atomic mass of it is 204. Atomic number of it is 81.
atomic # = protons atomic mass - atomic number = neutrons atomic # - charge = electrons
protons plus neutrons = atomic number
the Atomic Mass number is the number of protons/electrons in an atom
the Atomic Mass number is the number of protons/electrons in an atom
