Question 1

An element 'X' is characterized by an extremely high first ionization energy and a general inertness towards chemical reactions under standard conditions. Element 'Y', located in the same period as 'X', exhibits a very low first ionization energy and is highly reactive, readily forming cations. Which of the following conclusions can be drawn about elements X and Y based on their periodic positions and properties?

Accepted Answer

C. Element X is a noble gas, and Element Y is an alkali metal. — Noble gases (Group 18) possess full valence shells, resulting in exceptionally high ionization energies and chemical inertness, fitting the description of element X. Alkali metals (Group 1) have only one valence electron, leading to very low ionization energies and high reactivity to form +1 cations, matching element Y. Other options describe elements with different ionization energy characteristics or reactivity patterns that do not align with the extreme properties given for X and Y.

Answer

A. Element X is a transition metal, and Element Y is a Group 14 element.

Answer

B. Element X is a non-metal from Group 15, and Element Y is a metal from Group 13.

Answer
