There are five Family on the periodic table that are alkali metals , Alkaline earth metals , transition metals , Halogens family and noble gas family.
1) In alkali metals, there are six elements are present and among all the elements Sodium metal should be selected. Because sodium metal is most abundant metal in the world.
- uses of sodium are
- sodium salt are common salt that added to the food to enhance the taste.
- washing soda are made up of sodium salt which is used as water softener.
- sodium salts are also used as buffer to maintain Ph.
2) In alkaline earth metal family, The magnesium element should be selected.
- uses of magnesium are
- since magnesium is a soft metal so it can burn easily therefore it is used in fire works.
- magnesium is also important for proper growth and maintenance of bones.
- Magnesium is light weight metal so it can used to make car seat , luggage and power tools etc.
3) In Halogens gas family , chlorine should be selected.
- Uses of chlorine are
- The chlorine is used in cleaning purpose as it act as bleaching agent.
- Chlorine is also used to prepare the pesticides to removes pest in crops.
- In refrigerators, the cold breeze is coming out is chlorine gas which are used to increase the shelf life of the plants.
4) In transition metals , copper metal should be choose.
- Use of copper metal are
- Copper is highly ductile metal so it drawn into wires and used in various electrical purpose.
- The copper has anti corrosive properties so it can used in making kitchen utensils.
- The copper has anti microbial property so it can used in packaging of food.
5) In noble gas elements, The helium gas should be selected
- uses of helium gas are
- It used as semiconductors.
- It used in party balloons.
- The helium is inert gas so it used to make optical fibers.
These are the daily life usage of all the elements of each family of the periodic table.

Steam distillation is a separation process for temperature sensitive materials and it is used for purification of organic compounds.
The water vapor carries small amounts of the vaporized compounds (water and organic molecules) to the condensation flask. This is preferred technique because allows easy separation of the components by decantation or other suitable methods, because product od distilation is a two phase system<span> of water and the organic distillate.</span>
<u>1) find molar mass of CH₄</u>
<u>2) determine moles of CH₄</u>
<u>3) multiply by avogadro's number</u>
HCl is NOT an organic molecule.
It contains <em>no carbon</em>.
All the other compounds are organic because they contain both C and H.
