![Mind Map: Metals and Non-Metals](https://www.mindmeister.com/image/xlarge/1575310340/mind-map-metals-and-non-metals.png)
1. Metals
1.1. Physical properties
1.1.1. they are solids
1.1.2. high density
1.1.3. malleable and ductile
1.1.4. good conductor of heat and electricity
1.2. Chemical properties
1.2.1. meral+ O2---> metal oxide
1.2.2. metal + water ---> metal oxide+ hydrogen
1.2.3. Metal + Dilute acid ---> Salt+H2
1.2.4. Metal+Cl2---> Metal oxide
1.2.5. Metal+H2---> Metal Hydride
2. Corrosion
2.1. A process in which metal reacts with substances present in the atmosphere to form surface compounds.
3. Activity series of metal or reactivity series
3.1. K > Na > Ca > Mg > Al > Zn > Fe > Sn > Pb > H > Cu > Hg > Ag > Au
4. Non-Metals
4.1. Physical Properties
4.1.1. Can be solids,liquids or gas
4.1.2. brittle
4.1.3. non-malleable and non-ductile
4.1.4. poor conductor of electricity
4.2. Chemical Properties
4.2.1. non-metal + O2--> non-metal oxide
4.2.2. non-metal + steam ---.> H2 + non-metal oxide
4.2.3. non-metal+acid ---> no reaction
4.2.4. non-metal + Cl2 ---> non-metal chloride
