Identify the group and valency of element have atomic number 119 also predict the outermost electronic configuration and general formula of oxide
Answers
The present set up of the Long Form of the Periodic Table can accommodate at the maximum 118 elements. After this, according to Aufbau principle, 8.y-orbital should be filled. Therefore, the outer electronic configuration of element having atomic number 119 will be 8s1. Since it has one electron in the outermost s-orbital, its valency will be 1 and it should belong to group 1 along with alkali metals. The general formula of its oxide will be M20, where M represents the element.

Explanation:
The present set up of the periodic table is can accommodate at the maximum 118 elements.After this according to Aufbau principle,8. y- orbital should be filled. therefore the outer electronic configuration of element having atomic number 119 will be 8s1. since it has one electron in the outer most s-orbital, it's valency be 1 and it should be belong to group 1 along with alkali metals.
The general formula of it's oxide is M2O, where M represent the element
