Observe the following statements.
Statement (A) In general, the ionisation potential value decreases on moving down in the group.
Statement (B) The lst ionisation potential of sodium is greater from that of potassium. Correct answer is
- A Both \(A\) and \(B\) are incorrect.
- B Both \(A\) and \(B\) are correct.
- C \(A\) is correct but \(B\) is incorrect.
- D \(A\) is incorrect but \(B\) is correct.
Answer & Solution
Correct Answer
(B) Both \(A\) and \(B\) are correct.
Step-by-step Solution
Detailed explanation
Ionisation energy is the energy required to remove an electron from an isolated gaseous atom. Ionisation potential decreases as we move down in the group. The atomic number increases in a group and hence the number of shells also increases. Thus, outermost electrons are far away…
