Does zinc have a high melting point
WebJun 10, 2024 · Thus copper melts at 1,083 ∘ C, while zinc melts at 419 ∘ C and boils at 907 ∘ C. So, in making brass, if we just put pieces of copper and zinc in a crucible and heated them above 1,083 ∘ C, both the metals would certainly melt. But at that high temperature the liquid zinc would also boil away and the vapour would oxidize in the air. WebMay 20, 2024 · Because Zn has a filled valence shell, it should not have a particularly high melting point, so a reasonable guess is C 6(CH 3) 6 < Zn < RbI < Ge ⋅ The actual melting points are C 6 (CH 3) 6, 166°C; Zn, 419°C; RbI, 642°C; and Ge, 938°C. This agrees with our prediction. Exercise 12.7.1
