Metals N5
Found on the LHS of the periodic table
Solid at room temperature ( except mercury)
Often shiny, flexible ductile,
High melting and boiling points
atoms held together by metallic bonds
an electrostatic force of attraction between the positively charged metal ions, and the negatively charged delocalised electrons.
Conducts electricity
because the electrons are free to move around
metals for ions they lose electrons to form positive ions
The electrochemical series is a list of metals arranged in rank order of how easily the metal atoms lose electrons.
Metals at the top, like sodium & lithium, lose electrons easily
Reactions of metals
Metal + Water -> metal hydroxide + hydrogen
metal + acid -> salt + hydrogen
metal + oxygen -> metal oxide
metals above hydrogen in the ECS
Na, Ca, Li, K
All except Au
Ores are naturally occurring rocks that contain metals
REDOX
Displacement
Reduction
Oxidation
loss of electrons
gain of electrons
A metal higher in the ECS displaces one lower ECS from a solution
