1. Who discovered x-rays?
A) Thomas Edison
B) Marie Curie
C) Wilhelm Conrad Roentgen
D) Nikola Tesla
Correct Answer: C) Wilhelm Conrad Roentgen
Rationale: Wilhelm Conrad Roentgen discovered x-rays on
November 8, 1895, while experimenting with cathode ray tubes.
He received the first Nobel Prize in Physics in 1901 for this
discovery .

,2. What is a proton?
A) A negatively charged particle in orbital shells
B) A positively charged particle in the nucleus of an atom
C) A particle with no electrical charge in the nucleus
D) A charged particle resulting from ionization
Correct Answer: B) A positively charged particle in the nucleus
of an atom
Rationale: Protons are positively charged subatomic particles
located in the nucleus of an atom. The number of protons
determines the atomic number of an element .
3. What is a neutron?
A) A positively charged particle in the nucleus
2
, B) A negatively charged particle in orbital shells
C) A particle with no electrical charge in the nucleus
D) A particle that orbits the nucleus
Correct Answer: C) A particle with no electrical charge in the
nucleus
Rationale: Neutrons are neutral particles (no charge) located in
the nucleus along with protons. They contribute to the atomic mass
but not the atomic number .
4. What is an electron?
A) A positively charged particle in the nucleus
B) A neutral particle in the nucleus
C) A negatively charged particle in orbital shells around the
nucleus
D) A charged particle resulting from radiation exposure
3
, Correct Answer: C) A negatively charged particle in orbital
shells around the nucleus
Rationale: Electrons are negatively charged particles that orbit
the nucleus in specific energy shells or orbitals. They are
responsible for chemical bonding and are involved in x-ray
production .
5. What is an ion?
A) A neutral atom
B) A charged particle
C) A type of x-ray photon
D) A molecule of water
Correct Answer: B) A charged particle
Rationale: An ion is an atom that has gained or lost one or more
