Density
[edit]omg.. good work, dude
Excellent table. The only correction I would like to suggest is changing the unit for density from the obsolete g/cm^3 to kg/m^3. I tried to do this, but didn't succeed so I left it untouched.Ásgeir IV. (talk) 15:58, 17 June 2008 (UTC)

The boiling and melting points are off. according to https://www.rsc.org/periodic-table/element/29/copper Please change the Boiling point numbers to 2560°C, 4640°F, 2833 K please change the Melting point numbers to 1084.62°C, 1984.32°F, 1357.77 K Loganscott74 (talk) 21:12, 17 October 2019 (UTC)
Not done: The ILO's data claims a BP of 2595°C and MP of 1083°C. I'm certain many other refs would claim all slightly different temperatures. This is too small a change to care really as most refs are slightly different. comrade waddie96 ★ (talk) 18:15, 28 October 2019 (UTC)
- m.p. sourced in Melting_points_of_the_elements_(data_page)#Cu, b.p. sourced in Boiling_points_of_the_elements_(data_page)#Cu. Varies indeed. -DePiep (talk) 19:17, 28 October 2019 (UTC)

[edit]Copper is a metal that has a high melting point and high boiling point.It is a conductor of heat and electricity .It can make hard ware and coin — Preceding unsigned comment added by 41.116.31.11 (talk) 14:02, 23 April 2022 (UTC)
