On the Periodic Table, there are three major types of elements known as Metals, Non-Metals, and Metalloids. Here are a few properties of metals and non-metals.
1. Metals are generally shiny, malleable, and hard. Metals are also good conductors of electricity. Examples of metals are Gold, Silver, Iron, Uranium, and Zinc.

2. Non-metals do not conduct heat or electricity very well. Non-metals are typically brittle and are not easily molded into shapes. Example non-metal elements are Hydrogen and Carbon.

mark it as best plzzzzzzzz
a metal is an element which can form positive ions bylosing electrons .the numbers of electron lost by one atom of a metal is called the valence of metal sodium,potassium ,magnesium and aluminium are metal because they can form positive ions by losing electrons 
physical propersties of metal 
metal are lustrous
metals are malleable
metals are ductile
metals are good conductor of heat and electricity 
metals are solid 
metals have high melting and boiling boints 
metal have high densities 
metals are sonorous

reaction of metal with oxygen gives metal oxide
reactiomn of metal with water gives metaloxide and hydrogen gas 
reaction of  metal with dilute acid gives metal salt and hydrogen gas 

non metal 
there are very few non metal as compared to metal .at room temperature non metal are either solid or gaseous ,except bromine which is liquid .hydrogen ,nitrogen,oxygen, chlorine are example of some gaseous metal and carbon ,phosphorous and sulphur are some solid non metals

physical properties of non metal 
they are brittle
they are neither malleable nor ductile 
they are bad conductor of heat and electricity except graphite
non metal form acidic oxode or basic oxide non metal are covalent chloride 
non metal are non sonorous .

hope this information helps u .
