JEE Main & Advanced Chemistry Classification of Elements and Periodicity in Properties / तत्त्वों का वर्गीकरण एवं गुणों में आवर्ति Question Bank Self Evaluation Test - Classification of Elements and Periodicity in Properties

Consider the following changes \[A\to {{A}^{+}}+{{e}^{-}}:{{E}_{1}}\] and \[{{A}^{+}}\to {{A}^{2+}}+{{e}^{-}}:{{E}_{2}}\].

The energy required to pull out the two electrons are \[{{E}_{1}}\] and \[{{E}_{2}}\] respectively. The correct relationship between two energies would be

A) \[{{E}_{1}}<{{E}_{2}}\]

B) \[{{E}_{1}}={{E}_{2}}\]

C) \[{{E}_{1}}>{{E}_{2}}\]

D) \[{{E}_{1}}\ge {{E}_{2}}\]

Correct Answer: A

Solution :

\[I{{E}_{1}}\]is always less than\[I{{E}_{2}}\].
