Chemistry
1. Which statement accurately describes the relationship between electron configuration and the periodic table?
- A. Elements within the same period have similar electron configurations.
- B. Elements within the same group have similar electron configurations in their outermost shell.
- C. Electron configuration has no influence on an element's position on the periodic table.
- D. The number of electron shells an element has determines its group on the periodic table.
Correct answer: B
Rationale: Elements within the same group have similar electron configurations in their outermost shell. This explains why elements in the same group often share similar chemical properties.
2. Which element shares the same group (family) on the periodic table with helium (He)?
- A. Neon (Ne)
- B. Boron (B)
- C. Carbon (C)
- D. Oxygen (O)
Correct answer: A
Rationale: Neon (Ne). Both He and Ne belong to Group 18 (Noble Gases) due to their complete and stable outer electron shells.
3. What is the purpose of the periosteum, the tough outer layer of bone?
- A. Produces red blood cells
- B. Provides protection and nourishment to bone
- C. Forms the joint surface
- D. Stores minerals
Correct answer: B
Rationale: The correct answer is B: 'Provides protection and nourishment to bone.' The periosteum is a tough outer layer of bone that serves multiple functions. It provides protection by acting as a barrier against infections and injuries. Additionally, the periosteum contains blood vessels that supply nutrients to the bone cells, aiding in bone growth, repair, and maintenance. While red blood cells are produced in the bone marrow, not in the periosteum, the periosteum's primary role is to support the overall health and integrity of the bone structure.
4. Photons, the basic unit of light, are:
- A. Charged particles
- B. Packets of energy with wave-particle duality
- C. Electromagnetic waves only
- D. Always absorbed by matter
Correct answer: B
Rationale: The correct answer is B: Packets of energy with wave-particle duality. Photons are the smallest discrete amount of electromagnetic radiation and exhibit both wave-like and particle-like properties. While photons do not have a charge, they do carry energy and momentum. This dual nature of photons is a fundamental concept in quantum mechanics. Photons can travel as both waves and particles, and their behavior is described by the wave-particle duality principle. Therefore, option B accurately describes the nature of photons as packets of energy with wave-particle duality.
5. The phrase "massive open online courses" (MOOCs) refers to
- A. Online learning platforms designed specifically for students with disabilities.
- B. University-level courses freely available to anyone with an internet connection.
- C. Interactive training modules aimed at developing job-specific skills and knowledge.
- D. Online resources offering personalized learning experiences tailored to individual needs.
Correct answer: B
Rationale: MOOCs by definition are open and accessible courses, aligning with B.
6. Which force opposes the relative motion between surfaces in contact?
- A. Tension force
- B. Frictional force
- C. Gravitational force
- D. Magnetic force
Correct answer: b
Rationale: Friction is the force that opposes motion between surfaces in contact.
