Question

what is average atomic mass with examples

Answer 1

Explanation:

Neon has three natural isotopes: 90.48% of Neon is Ne-20 with a mass of roughly 19.992 amu; 9.25% is Ne-22 with a mass of 21.991 amu; and 0.27% is Ne-21 with a mass of 20.993 amu.

Answer 2

what is average atomic mass

Calculating Average Atomic Mass. The average atomic mass of an element is the sum of the masses of its isotopes, each multiplied by its natural abundance (the decimal associated with percent of atoms of that element that are of a given isotope). ... The atomic number of chlorine is 17 (it has 17 protons in its nucleus).
