IIT/JEE Chemistry Practice #12: Atomic Structure

Dave explains multiple-choice questions on atomic structure, covering isotopes, zinc ion neutron calculation, Rutherford's gold foil experiment, and the Bohr model. He emphasizes understanding atomic structure and suggests reviewing previous tutorials for better comprehension.

What are atoms with the same atomic number but different mass numbers called?

• Isobars

• Nuclides

• Ions

• Isotopes

How many neutrons are in a zinc ion with a mass of 70 atomic mass units?

• 35

• 45

• 40

• 30

What did Rutherford's gold foil experiment reveal about the structure of an atom?

• Atoms are solid spheres

• Atoms have a dense nucleus

• Atoms are mostly filled with electrons

• Atoms have no internal structure

Which model explains the spectrum of any atom or ion with one electron?

• Rutherford Model

• Bohr Model

• Quantum Model

• Thomson Model

Which of the following is true about the Bohr model?

• It applies to atoms with multiple electrons

• It only works for hydrogen

• It can explain spectra of single-electron ions

• It is the most accurate model for all atoms
