Chapter 2: Structure of Matter (20 Questions) | | | | | |
1. What is the primary source of electrons in an X-ray tube?
| | | | | | | | | | |
||| - A) Anode target
| | | ||
||| - B) Cathode filament
| | | ||
||| - C) Collimator
| | ||
||| - D) Grid
| | ||
**Answer**: B) Cathode filament
||| | | | ||
**Rationale**: The cathode filament releases electrons via thermionic
||| | | | | | | |
emission when heated, critical for X-ray production.
| | | | | | |
2. Which atomic component determines an element’s chemical
| | | | | | |
properties?
|
, ||| - A) Neutrons
| | ||
||| - B) Protons
| | ||
||| - C) Electrons
| | ||
||| - D) Nucleus
| | ||
**Answer**: C) Electrons
||| | | ||
**Rationale**: Valence electrons govern chemical bonding, as described
||| | | | | | | |
in the book’s atomic structure section.
| | | | | |
3. What is the binding energy of K-shell electrons compared to outer
| | | | | | | | | | |
shells?
|
||| - A) Lower
| | ||
||| - B) Equal
| | ||
||| - C) Higher
| | ||
||| - D) Unrelated
| | ||
**Answer**: C) Higher
||| | | ||
**Rationale**: K-shell electrons, closer to the nucleus, have higher
||| | | | | | | | |
binding energy due to stronger attraction.
| | | | | |
4. Which radiation is emitted during electron shell transitions?
| | | | | | | |
||| - A) Alpha
| | ||
||| - B) Beta
| | ||
||| - C) Electromagnetic
| | ||
||| - D) Neutron
| | ||
**Answer**: C) Electromagnetic
||| | | ||
**Rationale**: Electron transitions produce characteristic X-rays, a key
||| | | | | | | |
Chapter 2 concept.
| | |
,5. What primarily determines an atom’s mass?
| | | | | |
||| - A) Electrons
| | ||
||| - B) Nucleus
| | ||
||| - C) Valence shells
| | | ||
||| - D) Orbitals
| | ||
**Answer**: B) Nucleus
||| | | ||
**Rationale**: Protons and neutrons in the nucleus account for nearly all
||| | | | | | | | | | |
atomic mass.
| |
6. Which subatomic particle has no charge?
| | | | | | |
||| - A) Proton
| | |
||| - B) Electron
| | ||
||| - C) Neutron
| | ||
||| - D) Photon
| | ||
**Answer**: C) Neutron
||| | | ||
**Rationale**: Neutrons are neutral, affecting mass but not charge, per
||| | | | | | | | | |
the book.
| |
7. What is the role of the electron cloud in an atom?
| | | | | | | | | | |
||| - A) Stores nuclear energy
| | | | ||
||| - B) Determines atomic number
| | | | ||
||| - C) Governs chemical interactions
| | | | ||
||| - D) Emits X-rays
| | | ||
**Answer**: C) Governs chemical interactions
||| | | | | ||
, ||| **Rationale**: The electron cloud contains valence electrons driving | | | | | | |
chemical bonds.
| |
8. Which element is commonly used in X-ray tube anodes?
| | | | | | | | | ||
||| - A) Copper
| | ||
||| - B) Tungsten
| | ||
||| - C) Aluminum
| | ||
||| - D) Lead
| | ||
**Answer**: B) Tungsten
||| | | ||
**Rationale**: Tungsten’s high atomic number and heat resistance make
||| | | | | | | | |
it ideal for anodes.
| | | |
9. **What happens when an electron is removed from a K-shell?**
| | | | | | | | | | ||
||| - A) Ionization
| | ||
||| - B) Fusion
| | ||
||| - C) Fission
| | ||
||| - D) Excitation
| | ||
**Answer**: A) Ionization
||| | | ||
**Rationale**: Removing a K-shell electron ionizes the atom, a precursor
||| | | | | | | | | |
to X-ray production.
| | |
10. **What unit measures atomic mass?**
| | | | | ||
|||| - A) Electron volt
| | | ||
|||| - B) Atomic mass unit (amu)
| | | | | ||
|||| - C) Joule | | ||
|||| - D) Curie | | ||
