What are the chemical properties of metals & non-metals?
Chemical Property of Metals:Usually have 1-3 electrons in their outer shell. Lose their valence electrons easily.Form oxides that are basic.Are good reducing agents.Have lower electronegativities.Chemical Property of Non Metals: Usually have 4-8 electrons in their outer shell. Gain or share valence electrons easily.Form oxides that are acidic.Are good oxidizing agents.Have higher electronegativities.
What is the distinguishing chemical feature when metals react?
Answer When a metal reacts, it looses electron.
What are chemical properties of non metals?
Non-metals are also called electronegative elements because the non-metal atom form negatively charged ion by accepting electrons.1. Reaction of Non-metals with OxygenAll non-metals react with oxygen to form acidic or neutral oxides. For example, Carbon forms acidic carbon dioxide on reacting with oxygen.C+ O2 → CO2 ( Carbon Dioxide)2. Reaction of Non-metals with WaterNon-metals do not react with water.3. Reaction of Non-metals with Dilute AcidsNon-metals do not react with dilute acids and don’t displace hydrogen from dilute acids, because non-metals are electron acceptor. So, they cannot supply electrons to H+ ions. So, they do not displace hydrogen from dilute acids.4. Reaction of Non-metals with ChlorineNon-metals react with chlorine to form covalent chlorides. For example,H2 + Cl2 →2HCl ( Hydrogen chloride)5. Reaction of Non-metals with HydrogenNon-metals react with hydrogen to form covalent Hydrides. For example,H2 + S ----> H2S( Hydrogen sulphide)N2 + 3H2 ---> 2NH3 (Ammonia)Enjoy chemistry!
What are the chemical properties of metals and non-metal (in easy language)?
Chemical properties of metals:-Metals are easily corrodible2. Metals can lose electrons3. Metals can form basic oxides4. Metals have lower electronegativities5. Metals acts as very good reducing agentsChemical properties of non-metals:-Generally non metals contain 4-8 electrons in the outer shell2. Non metals readily lose or gain valence electrons3. Non metals form acidic oxides4. Non metals are high electronegative elements5. Non metals are great oxidizing agents
What is the chemical properties of metal?
The main property that makes metals special is their electropositivity. This means they form basic and amphoteric oxides.Basic: Oxide that releases a base in water.Amphoteric: Substance that can react as either an acid or a base.Metals usually have low ionization energy (energy needed to move the loosest bound electron) and lose electrons easily (Oxidation).Alkali metals bond to form 1+Alkaline earth metals bond to form 2+.Transition metals have varying patterns.
What are characteristics of non metals?
The characters of non metal are as follows.1)non metals are non luster.exception:diamond.2)non metals are brittleexception: diamond3) non metals are bad conducter of heat and electricityexception: graphite which is good conducter of electricity.4)non metals do not show melleability.Melleaility is the ability of a solid to be formed into a thin sheet on beating.5)non metals do not show property of ductility.Ductility is the ability of substance of being drawn into a wire.6)At normal room temperature non metals are in The solid or gaseous state.Exception: Bromine is in the liquid state.These are basic characters of non metal.Thanks for reading. I hope it is helpful for you.Best of luck for your future.
What are the characteristics of metal?
1.Metals are Malleable- This means that metal can be beaten into thin sheets with hammer(without breaking).Gold and siver are best malleable metals.Aluminium and copper are highly malleable metals. All the metals can be beaten with hammer to form thin sheets called foils.Ex-Silver is converted into thin sheets to form silver foils which is used to decorating sweets.2.Metals are ductile- This means that metals can be drawn into thin wires.Gold and silver are best ductile metals.Ex-100 milligrams of silver can be drawn into thin wire about 200 m.Copper and aluminium are also very ductile.3.Metals are good conductor of heat and electricity-Metals allow heat and electricity to pass through them very easily.Metals are good conductor of heat .They has the highly thermal conductivity.Copper and aluminium are best among them.that’s why cooking utensils are made up of copper and aluminium.Metals are good conductor of electricity .Copper and aluminium are best among them .That’s why electric wire is made up of copper and aluminium.4.Metals are lustrous-Gold,silver are shiny metals and they can be polished. The shiny appearance makes them useful in making jewellery5.Metals are sonorous-This means that metals make a ringing sound when we strike them.Due to this property metals are used for making bells.6.Metals are solid at room temperature-All the metals are solid at room temperature(except mercury).
What are the three characteristics of elements?
1.Any one of the simplest chemical substances that cannot be decomposed in a chemical reaction. 2. Chemical elements consist of atoms which have the same number of protons. 3. Each element has distinctive atomic number.
What are the differences between the properties of metals and nonmetals?
Metals, except mercury & gallium are solids at room temperature while non-metals , except bromine are solids or gases at room temperature.Metals are malleable and ductile while non-metals are non-malleable & non-ductileMetals are lustrous while non-metals, except diamond & graphite which are allotropes of carbon as well as iodine, are non-lustrous.Metals are good conductors of heat & electricity. Exception: Lead & mercury are poor conductors of heat. Non-metals are poor conductors of heat and electricity. Exception: Graphite conducts electricity.Metals except Na & K have high melting & boiling points while non-metals except diamond have low melting and boiling points.Metals except Na & K are hard while non-metals except diamond are soft.
