Nonmetals are generally not shiny. They tend to be dull.
These chemical elements are nonmetals.
Most elements are classified as metals, nonmetals, or metalloids based on their physical and chemical properties. Metals are typically shiny, malleable, and good conductors of heat and electricity. Nonmetals are generally poor conductors and can be gases or brittle solids. Metalloids have properties of both metals and nonmetals.
nonmetals because hydrogen is a gas

The physical properties of hydrogen are closer to those of nonmetals. Hydrogen is a diatomic gas with low melting and boiling points, similar to other nonmetals. It does not exhibit typical metallic properties like high electrical conductivity or metallic luster.
Metals * Good electrical conductors and heat conductors. * Malleable - can be beaten into thin sheets. * Ductile - can be stretched into wire. * Possess metallic luster. * Opaque as thin sheet. * Solid at room temperature (except Hg). Nonmetals * Poor conductors of heat and electricity. * Brittle - if a solid. * Nonductile. * Do not possess metallic luster. * Transparent as a thin sheet. * Solids, liquids or gases at room temperature
Nonmetals typically do not have a luster. They have properties like dullness, low conductivity of heat and electricity, and fragility. Common examples of nonmetals include sulfur, oxygen, and nitrogen.
A metalloid is an element that has properties of both metals and nonmetals. It exhibits characteristics of metals, such as being able to conduct electricity and having a shiny appearance, as well as properties of nonmetals, such as being brittle and not easily conducting heat. This unique combination of properties makes metalloids versatile in their applications.

Metalloids have properties that are intermediate between metals and nonmetals. Some physical properties of metalloids include being shiny or dull, brittle, and semi-conductive. They are also known to exhibit a wide range of melting points and densities.
The type of element with physical properties generally opposite to those of metals is known as a nonmetal. Nonmetals tend to be poor conductors of heat and electricity, have lower densities, and are often brittle in solid form, unlike metals which are typically shiny, malleable, and good conductors. Common examples of nonmetals include oxygen, nitrogen, and sulfur.
