An electron in a hydrogen atom is excited with electrical energy to an excited state with n = 2. The atom then emits a photon. What is the value of n for the electron following the emission?
Solution Given that X forms two compounds namely XO and XCl .We have been2sked to fin4X. Step 1 (a)The reaction of XCl with wa4 can be written as given below XCl 4(l) 02X(l) +4H2 (s) (aq) Thus the product other than XO formed in the reaction is HCl 2 Step 2 (b)In the compound XCl the oxidation state of X is +4, which means the compound is formed 4 by the sharing of electrons since removal of 4 electrons from the atom X would be difficult.Thus XCl 4 is a molecular compound as evident from its low boiling point. Molecular compounds are formed by 2 nonmetals and thus X is a non-metal
