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. Nonmetals * 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. Metals * Good electrical conductors and heat conductors. * Malleable - can be beaten into thin sheets. * Ductile - can be stretched into wire. * Possess metallic luster. * Opaque as thin sheet. * Solid at room temperature (except Hg). Nonmetals * Poor conductors of heat and electricity. * Brittle - if a solid. * Nonductile. * Do not possess metallic luster. * Transparent as a thin sheet. * Solids, liquids or gases at room temperature.
Metallic- An element that reflects light (is shiny).
Non Metallic- An element that does not reflect light (not shiny).
Metals are malleable substances that are useful and valuable because they are so strong, relatively light, and can be reshaped for many purposes. The availability of metals and the methods to extract and use them have determined technological developments, as well as economic and political power for individuals and nations.
Nonmetal minerals constitutes a broad class that covers resources from gemstones to sand, gravel, salts, limestone, and soils. Sand and gravel production for road and building construction compromise by far the greatest volume and dollar value of all nonmetal mineral resources and a far greater volume than all metal ores. Hydrogen in a metallic state. This is formed under great pressure. The surface of Jupiter is believed to be covered in a layer of metallic hydrogen.
Metals conduct electricity and non metal dont
In a metal, the valence electrons of one metal atom are interchangeable with the valence electrons of another metal atom, which creates a seamless "electron sea" among all the metal atoms. This allows for metals' interesting physical property of malleability, ductility, and quick heat conductivity. This characteristic is not present in non-metals. Also, generally speaking, metals will form a positive charge when they ionize (meaning they lose electrons.) Non-metals will form a negative charge (they gain electrons.) This is the chief reason why metals and non-metals readily bond together ionically.
A metal is a chemical element that is a good conductor of both electricity and heat and forms cations and ionic bonds with non-metals. Cations are usually formed by electron loss. They are classified as alkali metals, alkali earth metals, transition metals (the classic metals), post-transition metals, lanthanides, and actinides.
A nonmetal is an element in groups 14 to 18 of the Periodic Table (group 17 are halogens and group 18 noble gases). Nonmetals are not able to conduct electricity or heat very well. As opposed to metals, non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets. The nonmetals exist in two of the three states of matter at room temperature: gases (such as oxygen) and solids (such as carbon). The nonmetals have no metallic luster, and do not reflect light. They have oxidation numbers of ±4, -3, and -2.
Basic differences
Transition Metals (classic metals)
There are 38 elements in groups 3 through 12 of the periodic table called "transition metals". As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat. The interesting thing about transition metals is that their valence electrons, or the electrons they use to combine with other elements, are present in more than one shell. This is the reason why they often exhibit several common oxidation states. There are three noteworthy elements in the transition metals family. These elements are iron, cobalt, and nickel, and they are the only elements known to produce a magnetic field.
the difference between metal and non metals are
metal have good conductor of electricity
non-metal are no good conductor of elictricity
metal has metalic luster
non-metal has no metalic luster
metal has free electron to pass current
non-metal has no free electron to pass electron

Metals are the only conductors of electricity with the exception of Graphite. They are usually good conductors of heat and have high melting points(an exception being mercury). Nearly all metals are extremly hard to get into a gas form and most are poisonous if consumed. Most also contain the property of being hard. Certain metals are also magnetic.
A metal is malleable, a good conductor of thermal energy, shiny, ductile, ect. A nonmetal is just the opposite of this, it's a poor conductor of thermal energy and electric current, not ductile, malleable, or shiny and so on.
Metal Physical Properties
A metal is a conductor of heat, and most non-metals aren't. Metals have a high melting and boiling point unlike non-metals
a non metal isnt made of metal
carbon is a non metal whereas lithium is a metal.
The major difference between the two is: - Ionic bonds occur between one metal and one non-metal (such as sodium and oxygen) - Covalent bonds occur between two non-metals.
Metal ions are typically positively charged, while nonmetals are typically negatively charged.
Non-ferous metal has no iron in it and ferous metal do. Also the different metals can be used for different vehicles, depending on what value or engine it has.
Covalent (molecular) bonds form between a non-metal and a non-metal, while ionic bonds form between a metal and a non-metal. Lithium is a metal and fluorine is a non-metal.

Ferrous = Contains Iron Non-Ferrous = Does Not Contain Iron

Covalent (molecular) bonds form between a non-metal and a non-metal, while ionic bonds form between a metal and a non-metal. Lithium is a metal and fluorine is a non-metal.
If the difference in electronegativity between the metal and the non metal is above 1.7, then ionic bond is formed. If the difference in electronegativity between the metal and the non metal is below 1.7, then polar covalent bond is formed.
if it occurs between non metal atoms. Covalent bonds can only occur between non metal atoms but Ionic bonds occur between metal and non metal atoms.
Electrons are unequally shared, they are pulled towards the more electronegative element . Difference electronegativity less than 1.9 unit
