I removed sulfur nitride from the lede. It's considered a non-metal with some metallic properties. Its inclusion as a metal contradicts a) this article, b) the sulfur nitride article c) formal reference works on the topic. Its original inclusion in 2019 was unreffed.

I reverted this edit on June 20th and added supporting citations. Sandbh (talk)
The introduction discusses the "malleable" property of metal, but the hyperlink redirects to the "Ductility" page instead. Aeronchair (talk) 06:54, 18 August 2023 (UTC)[reply]
That is because malleability does not have a standalone article. It instead redirects to ductility, an article which discusses both properties, so the link is not broken. Complex/Rational 11:47, 18 August 2023 (UTC)[reply]
Can we clarify if graphite is considered a metal, Since it conducts electricity moderately well and seems to have the general characteristics (of a metal) in the introduction. Or, Is it too soft to be a metal ? - Rod57 (talk) 12:17, 12 March 2024 (UTC)[reply]
Article says "In physics, a metal is generally regarded as any substance capable of conducting electricity at a temperature of absolute zero.[2]" - Is it "generally regarded" or just one persons idea ? It's a very theoretical definition rather than being something that can be tested or measured. If true, it would make all materials, while superconducting, metals. A more usual definition of a metal might be having free electrons in a conduction band ? - Rod57 (talk) 12:33, 12 March 2024 (UTC)[reply]
