Total questions: 12
Worksheet time: 6mins
Which of the following would be held together by the metallic bond?
Atoms of iron (Fe)
Molecules of CH4
Atoms of sulfur (S)
Units of NaCl
The structure of metals includes
metal atoms sharing electrons
metal ions bonded to non-metal ions
cations surrounded by free-floating electrons
metal atoms giving electrons to other metal atomes
Metals conduct electricity because
there is large band gap between valence band and conductor band
the valence band and conductor band overlap
electrons in valence band stay and let conductor band empty
electrons in conductor band move to valence band
What does malleable mean?
Breaks easily
Always stays in the same shape
Can be drawn into wires
Can be forced into a certain shape without breaking
Why are metals malleable?
The metal ions can easily slide past one another
The metal ions cannot easily slide past one another
The metal ions repel one another
The metal ions attract one another
Why does copper wire conduct electricity when a potential difference is applied?
The crystal lattice breaks down
Copper (II) ions move to the cathode
The atoms of copper become ionised
electrons in valence band move to conductor band
Which of the following solids has a simple molecular lattice?
magnesium oxide
sulphur
silicon (II) dioxide
sodium
Which of the following metals has the lowest boiling point?
Aluminium
Copper
Potassium
Sodium
The melting point of magnesium is higher than that of sodium because
the relative atomic mass of sodium is less than that of magnesium
the metallic bonding in magnesium is stronger than that in sodium
the atoms in magnesium are packed more closely than the atoms in sodium
the atomic size of magnesium is larger than that of sodium
Which group of elements has similar bonds and is arranged in order of increasing melting point?
Na, Mg, Al
Li, K, Na
Pb, Si, C
Cl, S, P
Silicon has
gigentic covalent structure
simple molecular structure
metallic bond
Why Argon cannot exist in solid form?
the Van der Waals forces between Ar is very strong
Ar has very low melting and boiling point
Ar has very high meelting and boiling point
