Metals and Non-Metals
by Prerna Dutta
1. Non-Metals
1.1. Physical Properties
1.1.1. Can be solids,liquids or gas
1.1.2. brittle
1.1.3. non-malleable and non-ductile
1.1.4. poor conductor of electricity
1.2. Chemical Properties
1.2.1. non-metal + O2--> non-metal oxide
1.2.2. non-metal + steam ---.> H2 + non-metal oxide
1.2.3. non-metal+acid ---> no reaction
1.2.4. non-metal + Cl2 ---> non-metal chloride
2. formation of ionic compound when a metal and a nonmetal elements are continued for the transferring of their electrons to form an ionic compound.
3. Metals
3.1. Physical properties
3.1.1. they are solids
3.1.2. high density
3.1.3. malleable and ductile
3.1.4. good conductor of heat and electricity
3.2. Chemical properties
3.2.1. meral+ O2---> metal oxide
3.2.2. metal + water ---> metal oxide+ hydrogen
3.2.3. Metal + Dilute acid ---> Salt+H2
3.2.4. Metal+Cl2---> Metal oxide
3.2.5. Metal+H2---> Metal Hydride
