Describe the ionization of a metal
Explain the composition of metal crystals
What is metallic bonding?
Explain metallic bonding
Metals show a distinctive range of common physical properties. What are they?
Explain the outcome if sufficient force was applied to a metal
What happens when a voltage is passed through a metal?
Continue your answer with an explanation of the delocalized electrons.
Explain the distinctive properties of metals.
How can metallic bonds be described?
The stronger the bonding, the ____ the melting point.
What are the two factors controlling the strength of a metallic bond?
strength of metallic bond ∝ the number of valence electrons per atom
and inversely proportional to the size of the atoms involved.
strength of metallic bond ∝ 1 / metallic radius
the strength of metallic bonding therefore increases as we move across period ___.
Why do the transition metals tend to have very strong metallic bonds?
How are alloys produced/formed?
The productions of alloys is possible because of two factors. What are they?
In a pure metal, the layers of atoms can slide against each other if force is applied. This is not necessarily the same for alloys.
Why?
Do transition metals have higher mp than metals in group 1,2 or 3? Why?
