Is tungsten a metal or nonmetal or metalloid?
Because tungsten is a rare metal and its compounds are generally inert, the effects of tungsten on the environment are limited. The abundance of tungsten in the Earth's crust is thought to be about 1.5 parts per million. It is one of the more rare elements.
Is tungsten generally classified as a metal or nonmetal or metalloid?

Tungsten
Tin, for example, has two allotropes: tetragonal "white" β-tin and cubic "grey" α-tin. White tin is a very shiny, ductile and malleable metal. It is the stable form at or above room temperature and has an electrical conductivity of 9.17 × 10 S·cm (~1/6th that of copper). Grey tin usually has the appearance of a grey micro-crystalline powder, and can also be prepared in brittle semi-lustrous crystalline or polycrystalline forms. It is the stable form below 13.2 °C and has an electrical conductivity of between (2–5) × 10 S·cm (~1/250th that of white tin). Grey tin has the same crystalline structure as that of diamond. It behaves as a semiconductor (as if it had a band gap of 0.08 eV), but has the electronic band structure of a semimetal. It has been referred to as either a very poor metal, a metalloid, a nonmetal or a near metalloid.

The term metalloid has also been used for elements that exhibit metallic lustre and electrical conductivity, and that are amphoteric, such as arsenic, antimony, vanadium, chromium, molybdenum, tungsten, tin, lead, and aluminium.
Metalloid
Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements.

In chemistry, an amphoteric compound is a molecule or ion that can react both as an acid and as a base.
Amphoterism
Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. However, tungsten and other metallic elements can also be described as metalloids for their metallic luster, electrical conductivity, and amphoterism, or ability to act both as an acid and a base.
