Wood's metal
« on: August 04, 2005, 05:24:33 PM »
How can wood's metal have a lower boiling pt than it's constituent parts?

How can water have a higher melting point than its constituent parts of Hydrogen and Oxygen gas? If you change the Chemistry you change the chemical properties and physical properties of the substance.

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

weaker metallic bonding. try to explain that in terms of metallic lattice structure.

Mitch it's an alloy, not a chemical compound.
@geodome
So how does the lattice structure change?

how does having different-sized metal cation in the lattice affect its packing?

different cation would have different proton number and ionic radii. how does that affect the strength of the metallic bonding?

overall, how does it all contribute to overall weaker extent of metallic bonding, leading to a lower melting point?
