Chlorine is made up of 75.78% 35cl and 24.22% 37 cl. The atomic mass of 35 CL is 34.969 amu. The atomic mass of 37 CL is 36.966 amu. What is the average atomic mass of a sample of chlorine?

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
