Question

Identify the group and valency of element have atomic number 119 also predict the outermost electronic configuration and general formula of oxide

Answer 1

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.

Answer 2

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
