How do you find the atomic number
WebThe atomic number of an atom is equal to the number of protons in the nucleus of an atom or the number of electrons in an electrically neutral atom. Atomic number = Number of … WebStep 1: Multiply the atomic mass of the isotope with its abundance percentage and divide the result by 100. Step 2: Add the values gained from step 1 for each given isotope in the sample. Example: Calculating the atomic mass of a given chlorine sample where two isotopes are mixed.
