Explanation:

To solve this, we use the properties of conductors, semiconductors, and insulators:

Conductors:

• Have high electrical conductivity (electrons move freely).
• Include Metals (e.g., copper, iron) and alloys like Brass (metal - based, conducts well).
• “Band gap = 0.01 eV” is very small (almost no gap), so electrons can easily move → conductor.

Semiconductors:

• Have moderate conductivity (between conductors and insulators).
• Include Metalloids (e.g., silicon, germanium) and materials with “Band gap = 1 eV” (typical for semiconductors, e.g., silicon has ~1.1 eV).
• “Gallium” is a metalloid - like element used in semiconductors (e.g., gallium arsenide).

Insulators:

• Have no electrical conductivity (electrons are tightly bound).
• Have large band gaps (e.g., “Band gap = 4 eV” for materials like glass, which is an insulator).
• “Non - metals” like sulfur, carbon (in diamond form) are insulators.

Categorization:

• Conductors: High electrical conductivity, Metals, Brass, Band gap = 0.01 eV
• Semiconductors: Moderate conductivity, Metalloids, Band gap = 1 eV, Gallium
• Insulators: No electrical conductivity, Non - metals, Band gap = 4 eV, Glass

Answer:

• Conductors: High electrical conductivity, Metals, Brass, Band gap = 0.01 eV
• Semiconductors: Moderate conductivity, Metalloids, Band gap = 1 eV, Gallium
• Insulators: No electrical conductivity, Non - metals, Band gap = 4 eV, Glass
