Question

Why iron has higher melting point than copper?

Answer 1

The attraction between the metal ions and the delocalised electrons must be overcome to melt or to boil a metal. ... These attractive forces are strong, so metals have high melting and boiling points.

Answer 2

Iron has a higher melting point than copper because of its properties - its texture, its atomic structure. It is just the way nature created it. You can't really answer why, unless you want the excact properties of iron that enable it to have a high melting point than copper.
