The source I used (see the link under the related links section) states that:
Boron does not have a distinct luster as it is typically found in an amorphous powder form. It is a non-metal and does not display metallic luster like other metals.
Lustre Is An Property Of Metals: Thus All Metals Have Lustre However Lead Being A Metal Is Considered To Be Non Lustrous But Actually Lead Is Bright And Silvery When Freshly Cut But The Surface Rapidly Tarnishes In Air To Produce A Dull Lustre Associated With Lead.
bromine is a non-metal which stays as a liquid in room temp
Yes, leather is a non-metal material. It is made from the tanning of animal hides, typically from cows, and is a natural textile that is flexible and durable.
No, but it's not a metal, either. A "non-metal" is an element, and "wood" is not a chemical element. So, wood is not a non-metal, and it's not a metal, either. Wood is a very complex substance made of many different molecules, which are made of many different atoms.
The non-metal that has lustre is graphite. It has a shiny appearance due to its layered structure that allows light to reflect off its surface.
Nitrogen typically has a dull lustre because it is a non-metal and does not reflect light well.
This chemical element is iodine.
The lustre of a metal is how shiny the metal is.There are two different types of lustre. One is metallic lustre, which is like the shininess of a polished metal surface. The other is non-metallic lustre, which is the opposite of metallic lustre, but is still shiny
Almost all metals are lustrous and shine and some non-metals like Graphite and iodine do have some lustre.
Boron does not have a distinct luster as it is typically found in an amorphous powder form. It is a non-metal and does not display metallic luster like other metals.
Bromine (Br) is the only non-metal which is liquid at room temperature and pressure.

Bromine (Br) is a liquid at room temperature and is a non-metal. The only liquid element that is not a metal is Bromine (Br). There is one other element that occurs in liquid form and that is Mercury (Hg).
The characteristic of non-metals are-1. Non-metals are gases or solids at room temperature, except bromine, which is liquid at room temperature.2. Non-metal solids are generally not as hard as metals and have low tensile strengths. However diamond, an allotrope of carbon, is very hard.3. They do not have luster. However, silicon, iodine and graphite have metallic lustre.
Carbon (C) is a natural chemical element, non metal.
All elements are either metal or non-metal. The most common non-metal elements are hydrogen, carbon, nitrogen and oxygen. See 'Related Links' below
