Diagram of the nuclear composition, electron configuration, chemical data, and valence orbitals of an atom of argon-40 (atomic number: 18), the most common terrestrial isotope of this element. Atomic structure refers to the structure of atom comprising a nucleus (center) in which the protons (positively charged) and neutrons (neutral) are present. Question 4. 29. 31. Here you can see the electron configuration of potassium. Ans. Atoms consist of a nucleus containing protons and neutrons, surrounded by electrons in shells. Potassium: is in period 3 - so has 3 shells of electrons; is in group 1 - so has 1 electron on its outermost shell; has a configuration of 2.8.8.1 because all shells must be filled before a new shell can contain electrons Question 4. The electron shell arrangements are quoted in numbers e.g. (a) (i) A proton is labelled. You should also realise because of the relatively small mass of the electrons most of an atom's mass is in the nucleus. Describe the structure of the beryllium atom.
