The negatively charged particles called electrons revolve around the centre of the nucleus. Which atom is not a metal. The protons have a positive charge the neutrons are neutral.
Diagram of the nuclear composition and electron configuration of an atom of calcium 40 atomic number.
Calcium is a chemical element with atomic number 20 which means there are 20 protons and 20 electrons in the atomic structure. This is an average number of neutrons as calcium has different isotopes which will contain different numbers of neutrons neutrons mass number atomic number so neutrons 40 20 neutrons 20. A calcium b potassium c strontium d yttrium 3 the table shows the atomic structure of four atoms. This means calcium has 20 protons and 20 electrons we can calculate the number of neutrons in the nucleus by using the following equation.
