Question

$StatementI-$ Zinc and berylium have electron affinities which are significantly different from each other.
$StatementII-$ Electron affinity is a measure of the energy used to add an electron to an atom.

• A. Statement $I$ is true, Statement $II$ is true
• B. Statement $I$ is true, Statement $II$ is false
• C. Statement $I$ is false, Statement $II$ is true
• D. Statement $I$ is false, Statement $II$ is false
• E. Statement $I$ is true, Statement $II$ is true and is a correct explanation of the phenomena described in $I$

Answer 1

The correct option is C Statement $I$ is false, Statement $II$ is true

$\text{1.Both Zinc and Berylium have 0 electron affinities. So Statement 1 is incorrect.}$

$\text{2.Electron affinity is a measure of the energy used to add an electron to become negative.}$

$\text{So statement ii is correct.}$
