Neon is neither dull nor shiny as it is a colorless, odorless, and inert gas. It is usually found in its gaseous state and does not have a particular luster or sheen.
Neon yellow generally appears bright and vibrant, so it would be more likely to have a shiny or glossy finish in design elements. Dull finishes are more associated with muted or matte colors.
Iodine is a non-metal element and appears as a shiny, dark purple solid when in its crystalline form.
Naturally occurring boron is dull, but it can be polished.

Silicon itself is a non-metallic element with a shiny luster. However, when it is in its pure form or as a compound, it may appear dull depending on how it is cut or polished. So, silicon can exhibit both dull and shiny characteristics depending on its context.
High purity must be shiny, but if oxidized it will become dull
