Question

An element x has atomic number 11.Where it is placed in the modern periodic table.Write the formula of its oxide.What type of compound is it.What is the action of litmus in asolution of its oxide.Why

Answer 1

Element X has an electron configuration of 1s²2s²2p⁶3s¹. The element belongs to group 1A of the periodic table since it has one valence electron in th outer shell and period three because it has three energy levels. The formula of the oxide of X is X₂O and it is an ionic compound because it is formed through the transfer of electrons. The X₂O is basic in nature and therefore will turn moist red litmus paper blue
