Zinc is held together by the attraction between Zn2+ ions
TRUE
false
don't know
"Silver has a high melting point because there are strong forces of electrostatic attraction between the Ag+ ions and the delocalised electrons."
good exam wording
exam wording could be better
don't know
A metal conducts electricity because the bonding electrons are "mobile"
TRUE
false
don't know
Mg has a high melting point because there are lots of strong ionic bonds to break
TRUE
false
don't know
The melting point of metals depends on the strength of the electrostatic attraction between the cations and the delocalised electrons
TRUE
false
don't know
Zinc powder, Zn(s), dissolves in water to become Zn(aq)
TRUE
false
don't know
The bonding electrons in Na come from the 3s-subshell
false
TRUE

Today we are going to look at "giant metallic lattice" structure.
What are the two types of structure we have covered already this year?
giant metallic lattice
giant covalent lattice
giant ionic lattice
simple molecular lattice
TICK ALL CORRECT STATEMENTS:
Be has a higher melting point than Li
Al has a higher melting point than Mg
Na has a higher melting point than Mg
TICK ALL CORRECT STATEMENTS:
The ionic radius of Be2+ is smaller than Li+
The melting point of Be(s) is higher than Li(s)
The ionic radius of Al3+ is smaller than Na+
The melting point of Al(s) is higher than Na(s)
