Non-metallic

Referring to a substance or element that lacks the characteristic properties of metals. This encompasses a diverse group of elements typically poor conductors of electricity and heat, often brittle, and lacking a metallic luster. Non-metals are generally located on the right side of the periodic table. They tend to gain electrons to form negative ions in chemical reactions. This contrast with metals, which readily lose electrons to form positive ions. non-metallic elements are crucial components in organic molecules and many essential compounds.

Non-metallic meaning with examples

• The scientist meticulously examined the sample, noting its lack of shine, ductility, and conductivity – all tell-tale signs that it was a non-metallic substance. The analysis confirmed it was elemental sulfur, often found near volcanoes and used in various industrial processes, a classic example of the element group.
• During the chemistry experiment, the students compared the reactions of a metallic strip to a non-metallic one. The non-metallic carbon rod, when placed in the acidic solution, exhibited no reaction, unlike the metal, highlighting the differing chemical behaviors of each group and their unique properties.
• The building's structure employed both metallic and non-metallic materials. The support beams were metallic for strength, while the insulation was made of non-metallic, such as fiberglass, to minimize heat transfer and improve energy efficiency, illustrating a mixed material approach.
• In assessing the conductivity of the circuit components, the technician identified a faulty wire. The wire, which was constructed from a non-metallic polymer, had degraded with age, thus preventing current flow and highlighting how its properties impact overall performance and dependability.
