The elements in theperiodic tablefor which the neutral atom has a valence electron configuration of ns²np⁴ are in the group 16, also known as the oxygen family. In this group, the elements sulfur (S), selenium (Se), tellurium (Te), and polonium (Po) have the ns²np⁴ electron configuration.The valence electronconfigurationrefers to the arrangement of electrons in the outermost energy level of an atom.In this case, the electron configuration is ns²np⁴ , where n represents any integer. The "ns²" part indicates that there are two electrons in the s sublevel of the outermost energy level. The "np⁴ " part indicates that there are four electrons in the p sublevel of the outermost energy level.Therefore, to find theelementsthat match this electron configuration, we look for elements in group 16 of the periodic table.Examples of elements in the oxygen family with the  ns²np⁴ configuration are:- Sulfur (S)- Selenium (Se)- Tellurium (Te)- Polonium (Po)These elements have sixvalence electrons,which means they can form compounds by either gaining two electrons or sharing two electrons to complete their outermost energy level and achieve a stable configuration.In summary, the elements sulfur (S), selenium (Se), tellurium (Te), and polonium (Po) in group 16 of the periodic table have the   ns²np⁴ electron configuration.For more such questions onperiodic tablevisit:brainly.com/question/1173237#SPJ1...
