प्रश्न
Given below are two statements:
Statements I: According to Bohr's model of an atom, qualitatively the magnitude of velocity of electron increases with decrease in positive charges on the nucleus as there is no strong hold on the electron by the nucleus.
Statement II: According to Bohr's model of an atom, qualitatively the magnitude of velocity of electron increase with a decrease in principal quantum number.
In light of the above statements, choose the most appropriate answer from the options given below:
पर्याय
Both statement I and statement II are false.
Both statement I and statement II are true.
Statement I is true but statement II is false.
Statement I is false but statement II is true.
उत्तर
Statement I is false but statement II is true.
Explanation:
It is evident from the formula `"v" prop "Z"/"n"` that the velocity of an electron in a Bohr orbit is directly related to the value of the atomic number (Z) and inversely related to the value of the primary quantum number (n).
