**Assertion (A):** In a triad, the three elements present have the same gaps of atomic masses.
**Reason (R):** Elements in a triad have similar properties.
The correct answer is option 'D' - Both A and R are false.
**Explanation:**
A triad is a group of three elements that have similar chemical properties and exhibit a consistent pattern of atomic mass differences. This concept was proposed by Johann Wolfgang Döbereiner in 1829. According to Döbereiner's triads, the atomic mass of the middle element in a triad is approximately equal to the average of the atomic masses of the other two elements.
However, the statement in Assertion (A) is incorrect. In a triad, the gaps between the atomic masses of the three elements are not necessarily the same. The atomic masses may vary, but they tend to show a pattern where the middle element has an atomic mass close to the average of the other two elements.
The statement in Reason (R) is also incorrect. While elements in a triad do have similar properties, it is not a defining characteristic of a triad. Triads are based on the pattern of atomic masses and not solely on the similarity of properties. Elements with similar properties can belong to different triads based on their atomic masses.
Therefore, since both Assertion (A) and Reason (R) are false, the correct answer is option 'D'.
**Reason (R):** Elements in a triad have similar properties.
The correct answer is option 'D' - Both A and R are false.
