What will be the name (IUPAC) and symbol if the element with atomic number 119 is discovered? Write its electronic configuration. Also write the formulas of the stable chloride and oxide of this element.

Explanation

IUPAC name: Unumenium, Symbol: Uue atomic number of the element=119=87+32. it is known that the element with atomic number 87 is francium (Fr). Fr belongs to group-1 in the 7th period of the periodic table. So, the element with atomic number 119 will take its position in group 1 and 8th period just below francium (Fr). electronic configuration of this element will be [Uuo]`Bs^(1)`. (where Uuo=Ununoctium, Z=118). it will be an alkali metal with valency=1. If the symbol of the element be 'M' then the formulas of its stable chloride and oxide will be MCl and `M_(2)O` respectively.
