The atomic number of Potassium is 19 and its mass number is 39. The number of neutrons its atom is A19 B39 C20 D58Submit Atomic number of an element is 30 and its atomic are weight is 65. The number of protons and neutrons are A30 and 65 B35 and 30 C35 and 65 D30 and 35Su...
Potassium K 20 Calcium Ca Conclusion Because an element’s chemical characteristics are determined by the number and arrangement of electrons in its atoms, these issues disappear when atomic number rather than atomic mass is employed to generate a periodic table. The nuclear charge, in turn, determ...
