Metallic Bonding is....
a chemical bond
not a chemical bond
these are formed as a result of the attraction between metal atoms and the surrounding "sea of electrons"
metallic bonds
Ionic bonds
covalent bonds
The blue negative signs (-) represent
cations
delocalized electrons
The red positive (+) signs represent
cations
delocalized electrons
Metals are good conductors of heat...
because they are shiny and reflect heat.
because the absorb heat.
the electrons are delocalised and able to move, colliding with cations to transfer themal energy.
because the cations can move freely to transfer thermal energy.
What are the 4 properties of metals
good conductors of heat and electricity, malleable, ductile, strong absorbers and reflectors of light
good conductors of heat and electricity, malleable, non ductile, weak absorbers of light
strong absorbers and reflectors of light, poor conductors of heat and electricity, malleable, ductile
Metal atoms can (a) other metal (b) , or occupy space between larger metal atoms to form (c) .
In metals, electrons are (a) , free to (b) about among structured positively charged.
Electronegativities are (a) meaning that the pull on (b) is (c) allowing those electrons to float and move among the atoms.
Which of these are properties of metals?
ductile and malleable
low melting or boil point
high melting/boiling point
conduct electricity
soluble in water
what charge do the metal ions have in metallic bonding?
negative
positive
neutral
Which two words/phrases describes the electrons in metallic bonding
delocalised
swimming
sea of electrons
fixed
flying
Why do metallic compounds conduct electricity as solids?
core electrons are mobile, allowing electricity to flow through the metal
valence electrons are mobile, allowing electricity to flow through the metal
protons are mobile, allowing electricity to flow through the metal
the metal cations are mobile, allowing electricity to flow through the metal
Metals are (a) because when a metal is hit, the metallic layers (b) each other. The (c) electrons (d) along with the cations. The metallic bond (e) break.
Which two elements form an alloy when heated together?
Chlorine and Hydrogen
Chlorine and zinc
Copper and hydrogen
Copper and zinc
Which diagram represents an alloy?
A
B
C
D
