Metal and Non-metal - Coggle Diagram
Metal and Non-metal
Metal - Physical Properties
Lustrus
Malleable
Ductile
Good conductor of heat and electricity
High melting point
Sonurus
Metal reaction with water
K, Na - react voilently and catch fire
Calcium starts floating
Magnesium - react with hot water - start floating
Al, Iron, Zinc - react with steam
Lead, Silver, Cooper, Gold - do not react with water
Aqua Regia - Royal water
mixture of conc. HCL and Nitric Acid
ration acid - 3:1
highly corrosive and fuming liquid
dissolve gold and platinum
Metal - Chemical Properties
Metal + Oxygen = Metal Oxide
Metal oxide - basic in nature
Metal oxide + acid = Salt + H2O
Amphoteric oxide - Zinc, Aluminium Oxide
Metal oxide + Water = Metal Hydroxide
Topic to read from book
Naturally occuring nitrated
Hardness of water
Temporary
Permanent
Anodising
Non - metals and some exception of properties
Strategic metals
Reaction of metal with oxygen
K, Na - react vigorously and catch fire
Magnesium, Aluminium, Zinc and Lead oxidize at regular temp
Hot copper gets coated with Black colour due to oxidation
Iron does not burn on heating but iron filling burns vigorously
silver and gold do not react with oxygen even at high temp
Reaction and metal and not metal
gives ionic compound/ electrovalent compound
do not exist as molecule but aggregates of opp. chareges ions
Properties of ionic compound
Physical nature
solid - somewhat hard
brittle - break under pressure
strong force of attraction
High MP and BP
Soluble in water, Insoluble in kerosene and petrol
Conductor of electricity
Solid state - do not conduct
Molten/aqeous state - conduct electricity
Chemical properties of metal
1-3 Valence elctron
Tendency to loose electron - forms cation
Low Electronegativity
Metal reaction with acid
H2 gas not evolved when HNO3 is used
HN03 - oxidzing agent
HNO3 gets reduced to any nitrogen oxide
H2 gas evolved when dilute HN03 used with Manganese and Mg
