Hence beryllium element has the electrons arrangement 2, 2. This electron arrangement indicates that the outermost orbit of Beryllium (Be) has 2 electrons. Hence, Beryllium lies in group 2. Web24 dec. 2024 · Chlorine consists of two major isotopes, one with 18 neutrons (75.77 percent of natural chlorine atoms) and one with 20 neutrons (24.23 percent of natural chlorine atoms). The atomic number of chlorine is 17 (it has 17 protons in its nucleus). To calculate the average mass, first convert the percentages into fractions (divide them by 100). fixa family protein
