metals - Coggle Diagram
metals
transition metals
high melting point
except mercury
high desity
conduct electricity and thermal energy
malleable and ductile
form coloured compounds
except zinc
used as catalyst
alloys
brass
stainless steel
used for cuttery
resistance to corrosion
hard
are a mixture of metals and another element
metalic bonding
a 3D repeating lattice between positive ions and negative delocalised electrons held together by strong forces of attraction
why do metals conduct electricity?
becuse there are free to move delocalised electrons between positive ions
why are metals malleable
because there are layers of positive ions that can slide past each other
