Question

why bismuth called an non metal ​

Answer 1

Bismuth is a chemical element in the periodic table that has the symbol Bi and atomic number 83.

This heavy, brittle, white crystalline trivalent poor metal has a pink tinge and chemically resembles arsenic and antimony.

Of all the metals, it is the most naturally diamagnetic, and only mercury has less thermal conductivity.

Lead-free bismuth compounds are used in cosmetics and in medical procedures.

Answer 2

Bismuth is a metal

This is because it has the capability of losing electrons during chemical reactions or bond formation

Bismuth is a chemical element with symbol Bi and atomic number 83. Bismuth, a pentavalent post-transition metal, chemically resembles arsenic and antimony.

Elemental bismuth may occur naturally, although its sulfide and oxide form important commercial ores. The free element is 86% as dense as lead.

It is a brittle metal with a silvery white color when freshly produced, but is often seen in air with a pink tinge owing to surface oxidation.

Bismuth is the most naturally diamagnetic element, and has one of the lowest values of thermal conductivity among metals
