Dielectric classification – definition of elemental dielectrics Elemental dielectrics are dielectrics composed of only one kind of atom (for example, noble gases like helium, neon, argon). Is this statement correct?

Introduction:
Dielectrics can be categorized by composition: elemental (single-atom species), molecular (multi-atom molecules), and compound/ceramic solids. This classification helps anticipate polarization mechanisms (electronic, ionic, orientation) and dielectric strength.

Given Data / Assumptions:

• Elemental substance contains one atomic species.
• Examples include noble gases (He, Ne, Ar) and solid elemental insulators such as sulfur in certain phases.
• Focus is on compositional definition, not on phase-dependent properties.

Concept / Approach:

An “elemental dielectric” is indeed a dielectric material made from atoms of a single element. In gases like helium or neon, polarization is entirely electronic; in solids composed of a single element, electronic and lattice contributions may appear, but compositionally they remain elemental. The statement as a definition is therefore correct.

Step-by-Step Solution:

Verification / Alternative check:

Textbook classifications separate elemental dielectrics from molecular ones like N2, CO2, H2O, and from ionic solids like NaCl or ceramics (Al2O3), confirming the definition.

Why Other Options Are Wrong:

Diatomic or metallic requirements are irrelevant; temperature qualifiers do not alter the compositional definition.

Common Pitfalls:

Confusing “elemental” with “monatomic gas only”; solids composed of a single element may also be dielectrics depending on structure.

Final Answer:

True
