Given below are two statements. Read the statements carefully and select the correct option.
Statement I: Bohr’s model could account for the stability and line spectra of hydrogen atom and hydrogen like ions (for example, He⁺, Li²⁺, Be³⁺ and so on).
Statement II: Bohr’s model could not explain the ability of atoms to form molecules by chemical bonds.
-
A.
Statement I is false but Statement II is true.
-
B.
Statement I is true but Statement II is false.
-
C.
Both Statements I and II are true.
-
D.
Both Statements I and II are false.
Correct Answer:
C. Both Statements I and II are true.
Explanation:
The two statements regarding Bohr’s atomic model are accurate. Statement I is correct because Bohr’s model successfully explained the stability of the hydrogen atom and provided a theoretical basis for the line spectra of hydrogen and similar single-electron ions like He+ and Li2+. Statement II is also correct because the model has significant limitations, such as its inability to explain the three-dimensional structures of atoms or how they bond to form molecules. Since both statements are factually sound, the correct option is that both Statements I and II are true.
