Graphical and Electrical Formulas of Fourth Period Elements (K, Ca)

Graphical Formula: The graphical representation of elements in the fourth period can be denoted by their electron configurations and orbital diagrams. For example, the electron configuration of potassium (K) is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹, and the orbital diagram would illustrate the distribution of these electrons in the different energy levels and sublevels. Similarly, for calcium (Ca), the electron configuration is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s², and the orbital diagram would depict the arrangement of electrons in the orbitals.

Electrical Formula: The electrical properties of elements in the fourth period can be represented by their valence electrons and their tendency to form ions. Potassium (K) has one valence electron in the 4s orbital, while calcium (Ca) has two valence electrons in the 4s orbital. This influences their reactivity and ability to form ions with specific charges.
