Atomic Structure and Isotopes

The video tutorial covers multiple-choice questions on atomic structure, including isotopes, neutron calculation in zinc ions, Rutherford's gold foil experiment, and the Bohr model. It explains isotopes as atoms with the same atomic number but different mass numbers, calculates neutrons in a zinc ion, and describes Rutherford's discovery of the atomic nucleus. The Bohr model's application to atoms with one electron is also discussed. The video concludes with a call to subscribe and support the channel.

What is the term for atoms that have the same atomic number but different mass numbers?

• Isomers

• Isobars

• Ions

• Isotopes

Which of the following is true about isotopes?

• They have the same number of protons.

• They have the same mass number.

• They have different atomic numbers.

• They belong to different elements.

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

• 50

• 40

• 30

• 44

What was demonstrated by Rutherford's gold foil experiment?

• Electrons are in fixed orbits.

• Atoms are indivisible.

• Atoms have a nucleus.

• Atoms are solid spheres.

Which model suggested that atoms are mostly empty space?

• Rutherford Model

• Dalton's Model

• Plum Pudding Model

• Bohr Model

Which experiment led to the discovery of the atomic nucleus?

• Dalton's Atomic Theory

• Bohr's Hydrogen Spectrum Experiment

• Rutherford's Gold Foil Experiment

• Thomson's Cathode Ray Experiment

What does the Bohr model explain?

• The chemical properties of elements

• The behavior of neutrons

• The spectrum of single-electron atoms

• The structure of multi-electron atoms

For which type of atoms is the Bohr model applicable?

• Atoms with one electron

• Atoms with no electrons

• Atoms with multiple electrons

• Atoms with two electrons

Which of the following atoms can the Bohr model accurately describe?

What is a limitation of the Bohr model?

• It cannot describe atomic nuclei.

• It only works for atoms with one electron.

• It cannot explain the spectrum of hydrogen.

• It does not account for protons.
