Electron configuration for element with atomic number 117 should be written. Concept introduction: Aufbau rule states that electrons must be filled in lowest energy levels first. For instance, electrons first occupy shells that are lower in energies illustrated as follows: Pauli’s exclusion principle states thatno two or more than two electrons of a poly electron atom can have same values of 4 quantum numbers that are n , l , m and s .It also states that only two electrons can occupy same orbital with opposite spins. Hund’s rule of maximum multiplicity states that electrons cannot be allowed to pair until each orbital gets singly filled with one electron. These 3 principles form basis for determination of electronic configuration.However, certain elements that are able to achieve nearest half-filled or fully filed configuration show exceptional configurations.

Solution Summary: The author explains Aufbau rule, which states that electrons must be filled in lowest energy levels first, and Hund's rule of maximum multiplicity.
Definition Definition Number of protons in the nucleus of an atom. It uniquely identifies an element, as the number of protons determines the element's properties. The periodic table of elements is arranged based on increasing atomic numbers, allowing scientists to easily locate and study elements.

Interpretation Introduction
Interpretation:Element that will resemble Uus most closely should be identified.
Concept introduction: Element that belongs to same vertical group has similar valance shell; configuration. Hence they exhibit similar chemical properties. For example, all alkali metals have one valence electron that makes them highly electropositive metal and all of them form similar oxides, halides, hydrides dye to same nature of outermost shell.

Interpretation Introduction
Interpretation:Formulas of the neutral binary compounds formed by Uus with Na , Mg , C , and O should be written.
