1. 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.

2. Elements tend to gain or lose electrons to achieve stable electron configurations like those of noble gases. Their group number often indicates the number of electrons gained/lost and the resulting ionic charge, providing a good starting point for prediction.

• A. Ionic bonds involve electron sharing, while metallic bonds involve electron transfer
• B. Ionic bonds are weak and directional, while metallic bonds are strong and non-directional
• C. Ionic bonds exist between metals and non-metals, while metallic bonds exist only between metals
• D. Ionic bonds form discrete molecules, while metallic bonds form extended structures

Correct answer: D

Rationale: Ionic bonds involve complete electron transfer between atoms, creating strong, non-directional electrostatic attraction. Metallic bonds involve a delocalized "sea" of electrons shared across all metal atoms, resulting in a strong, extended structure.

3. Which of the following is NOT a risk factor for developing atherosclerosis?

• A. High blood pressure
• B. High levels of LDL cholesterol
• C. Regular physical activity
• D. Smoking

Correct answer: C

Rationale: Regular physical activity is NOT a risk factor for developing atherosclerosis. In fact, engaging in regular physical activity can help reduce the risk of developing atherosclerosis by improving cardiovascular health, lowering blood pressure, and reducing LDL cholesterol levels. High blood pressure, high levels of LDL cholesterol, and smoking are all known risk factors for atherosclerosis. High blood pressure can damage blood vessels, making them more susceptible to plaque buildup. High levels of LDL cholesterol can lead to the accumulation of plaque in the arteries, narrowing the passageways and increasing the risk of atherosclerosis. Smoking is harmful to blood vessels, promoting inflammation and the formation of plaque. Therefore, regular physical activity is actually a protective factor against atherosclerosis rather than a risk factor.

4. What type of force opposes the motion of an object moving through a fluid (liquid or gas)?

• A. Gravitational force
• B. Tension force
• C. Viscous force
• D. Magnetic force

Correct answer: c

Rationale: Viscous force is the resistance experienced by an object moving through a fluid due to internal friction.

5. Which sentence avoids a dangling modifier?

• A. Walking down the street, a bird swooped down from a tree.
• B. Having finished the report, it was time for lunch.
• C. Reading the book, I learned a lot about ancient history.
• D. Exhausted from the hike, the tent was a welcome sight.

Correct answer: C

Rationale: Option C places the participle phrase "Reading the book" in front of the subject "I," eliminating the dangling modifier.

6. 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.
