Metals generally have high melting and boiling points because

there are strong forces between particles

Metallic bonding is best described as

attraction between delocalised electrons + positive nucleii

Metals conduct electricity because

valence electrons are free to move in the metal structure

These metals tend to react vigorously with water

Na, Ca (and freshly sanded Mg bubbles slowly)

Elements in the same period of the periodic table

Valence electrons are in the same energy level

Metals have relatively high densities because

the tightly packed arrangement of atoms

Malleability and ductility are metal properties as a result of

layers of atoms being able to slide over each other

Answers

1
Metals generally have high melting and boiling points because
the tightly packed arrangement of atoms
the valence shells contain electrons
valence electrons are free to move
there are strong forces between particles
2
Metal/s that don't react with water
Na and Ca
Mg, Al, Zn, Fe
Pb
Cu and Ag
3
Reacting Metal + Acid produces
Metal Oxide + hydrogen
Metal hydroxide + Hydrogen
Metal salt + Water
Metal + Hydrogen
4
Metallic bonding is best described as
strong forces between particles in metal
attraction between delocalised electrons + positive nucleii
strong forces between atoms
electrostatic attraction
5
Elements in the same group of the periodic table
Valence electrons are in the same energy level
Have increasing reactivity
Have different atomic numbers
Form ions with the same charge
6
Trend down a group on the periodic table
Increasing reactivity
Decreasing reactivity
Same number of valence electrons
Increasing number of electron levels
7
Properties of metals
Ductility and malleability
Lustre and shine
All of the above
Electrical and thermal conductivity
8
These metals tend to form oxide layers rather than burn in air
Na, Ca, Mg
Al, Zn, Fe
Pb and Cu
9
Metal/s that do not react with acid
Mg, Al, Zn, Fe and Pb
Na and Ca
Cu and Ag
10
Reacting Metal + Water produces
Metal salt + hydrogen
Metal + Hydrogen
Metal hydroxide + Hydrogen
Metal Oxide + hydrogen
11
Metals conduct electricity because
valence electrons are free to move in the metal structure
the atoms are surrounded by a "sea of valence electrons"
the tightly packed arrangement of atoms
the valence shells contain electrons
12

the atoms are large
the tightly packed arrangement of atoms
22
Reacting Metal + Steam produces
Metal salt + hydrogen
