One neutral gas and one monovalent metal
Answers
Answer:
a neutral gas is: dry hydrogen chloride gas
a monovalent metal is: lithuim, sodium, potassium basically any metal from the alkaline metals group in the periodic table.
Explanation:
dry hydrogen chloride gas and liquid hydrogen chloride are neutral in nature. this is because there is no formation of H+ and Cl- ions as there is a strong covalent bond between hydrogen and chlorine.
when HCl gas is dissolved in water it forms hydrochloric acid. This acid is acidic in nature due to the formation of H+ and Cl- ions and it is due to the chlorine ions that it turns moist blue litmus red.
Lithuim, Sodium, Potassium all are monovalent metals as they all have 1 electron in their valence (or outermost) shell. All elements having 1 electron in their outermost shell are termed monovalent metals.
i hope this answers someones question.
