Questions and Answers

1.

What is the smallest unit of an element?
- A.
  
  Molecule
- B.
  
  Atom
- C.
  
  Compound
- D.
  
  Particle
Correct Answer
B. Atom

Explanation
An atom is the smallest unit of an element, consisting of a nucleus (containing protons and neutrons) and electrons orbiting around it.

Rate this question:
2.

Which element is a noble gas?
- A.
  
  Oxygen
- B.
  
  Hydrogen
- C.
  
  Helium
- D.
  
  Carbon
Correct Answer
C. Helium

Explanation
Helium is a noble gas. Noble gases are characterized by their stable and inert nature, making them less likely to form chemical bonds with other elements.

Rate this question:
3.

What is the chemical symbol for gold?
- A.
  
  Gd
- B.
  
  Go
- C.
  
  Au
- D.
  
  Ag
Correct Answer
C. Au

Explanation
The chemical symbol for gold is Au, derived from its Latin name "aurum."

Rate this question:
4.

What type of chemical bond involves sharing of electrons?
- A.
  
  Ionic bond
- B.
  
  Covalent bond
- C.
  
  Metallic bond
- D.
  
  Hydrogen bond
Correct Answer
B. Covalent bond

Explanation
A covalent bond involves the sharing of electrons between atoms. This bond type is common between nonmetals and forms molecules.

Rate this question:
5.

What does pH measure in a solution?
- A.
  
  Temperature
- B.
  
  Pressure
- C.
  
  Concentration
- D.
  
  Acidity
Correct Answer
D. Acidity

Explanation
pH is a measure of the acidity or alkalinity of a solution. It indicates the concentration of hydrogen ions in the solution.

Rate this question:
6.

Which gas is responsible for the greenhouse effect?
- A.
  
  Oxygen
- B.
  
  Nitrogen
- C.
  
  Carbon dioxide
- D.
  
  Hydrogen
Correct Answer
C. Carbon dioxide

Explanation
Carbon dioxide (CO2) is a greenhouse gas that contributes to the greenhouse effect, trapping heat in the Earth's atmosphere and impacting global climate patterns.

7.

What is the process where a substance changes from a gas directly to a solid?
- A.
  
  Melting
- B.
  
  Condensation
- C.
  
  Deposition
- D.
  
  Evaporation
Correct Answer
C. Deposition

Explanation
The process where a substance changes directly from a gas to a solid without passing through the liquid phase is called "deposition." During deposition, the gas molecules or particles lose energy and come together to form a solid. This is the opposite of sublimation, where a substance changes directly from a solid to a gas without going through the liquid phase. Both deposition and sublimation are phase transitions that involve the conversion of matter between the gas and solid phases.

8.

How many elements are there in the periodic table?
- A.
  
  92
- B.
  
  118
- C.
  
  100
- D.
  
  86
Correct Answer
B. 118

Explanation
The periodic table currently consists of 118 elements, each uniquely characterized by its atomic number and properties

Rate this question:
9.

What is the unit of measurement for the amount of a substance?
- A.
  
  Liter
- B.
  
  Gram
- C.
  
  Kelvin
- D.
  
  Mole
Correct Answer
D. Mole

Explanation
A mole is the unit of measurement for the amount of a substance. It represents Avogadro's number of particles, which is approximately 6.022 x 10^23.

Rate this question:
10.

Which type of reaction involves the combination of two or more substances to form a single product?
- A.
  
  Decomposition
- B.
  
  Combustion
- C.
  
  Displacement
- D.
  
  Synthesis
Correct Answer
D. Synthesis

Explanation
A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product. It is often represented as A + B → AB.
