What would you observe when zinc is added to a solution of iron (II) sulphate ? Write the chemical reaction that takes place.

Elements are classified as metals and non-metals based on different properties. The properties of metals and non-metals are given in the form of table below-
Metals Non-metals
Metals are lustrous, that is, they have a property to shine.
They are not lustrous, that is, they do not have shining surface. except, graphite and iodine
All metals exist as solids except mercury which is liquid at room temperature.
They are generally soft, except diamond.
They can be drawn into wires, this is known as Ductility.
They are non-ductile.
Metals can be converted into sheets, this is known as Malleability, except mercury
They are non-malleable
They are good conductors of electricity and heat. Except Lead and mercury.
They are poor conductors of electricity and heat. Exception-graphite is good conductor of electricity
They have high density and high melting point. Exception-sodium and potassium have low melting points
They have low density compared to metals and low melting point except Diamond which has high melting point
Chemical Properties of Metals
Metals react with air or oxygen to form metal oxide.
For Example, Copper reacts with oxygen to form copper oxide.
Chemical Properties of Non-metals
Non-metals reacts with oxygen to form non-metal oxide.
Reactivity Series
The series in which metals are arranged in the decreasing order of reactivity, it is known as Reactivity Series.
Ionic Compounds
Compounds formed due to the transfer of electrons from a metal to a non-metal are known as Ionic Compounds.
Covalent Bond
Bond formed by sharing of electrons between the two atoms. They share their valence electrons to gain stability.
Properties of Ionic Compounds
They are generally hard and solid.
They have a high melting and boiling point.
They are soluble in water but insoluble in inorganic solvents such as ether etc.
They are conductors of electricity in molten and solution state.
Occurrence of Metals
Elements or compounds which occurs naturally in earth crust are known as Minerals. Minerals from which pure metals can be extracted are known as Mineral Ores.
Extraction of pure metals from its ores/steps for extraction of metals from its ore
The first step is enrichment of the ore.
Second step includes extraction of metals
Third steps involve refining of metal
Gangue - Ores contain different impurities in it such as sand, soil etc. These impurities are known as Gangue.
Extracting Metals which are low in activity series
Metals which are low in activity series are unreactive. The oxides of such metals can be reduced to metals by heating alone.
Extracting Metals in the middle of the Activity Series
These metals are moderately reactive. They exists as sulphides or carbonates in nature. Before reduction, metal sulphides and carbonates must be converted into metal oxides. Sulphide ores are converted into oxides by heating strongly in presence of excess air, this is known as Roasting. Carbonate ores are converted into oxides by heating in limited air.
Roasting
Calcination
Reduction-metal oxides can be reduced to metals using reducing agent such as such as Carbon.
Extracting metals towards the top of the activity series
The metals are highly reactive. They cannot be obtained by heating. For Example, Sodium, magnesium and calcium are obtained by the electrolysis of their molten chlorides.
Refining of Metals
Refining of impure metal is done using electrolytic refining. Impure copper is used as anode and strip of pure copper is used as Cathode. Acidified copper sulphate is used as electrolyte. When electric current is passed through this, impure metal from the anode gets deposited in the electrolyte solution, whereas pure metal from the electrolyte is deposited at cathode.
Deposition of insoluble residue formed from the dissolution of anode during commercial electrolysis. Corrosion Metals when exposed to moist air for a long period of time, they become corroded. This is known as Corrosion. Prevention of Corrosion Rusting of iron can be prevented by oiling, galvanizing, painting, greasing etc.To protect steel and iron from rusting, a thin layer of zinc are coated on them, this is known as Galvanization.
Alloy Mixture of two or more metals or metal and non-metal is known as Alloy. For Example, Brass is an alloy of copper and zinc.
Bronze in an alloy of copper and tin. Solder is an alloy of lead and tin. Amalgam is one metal is mercury. metals non metals class 10 vedantu,metals non metals class 10 notes,metals and non metals ncert class 10,
