Elements are not dangerous for human beings in fact the survival of human being and other organisms is possible only because of the element "oxygen"

Hydrogen - The first element of the periodic table involves in making water which makes human life sustainable.

Hydrogen is also used as fuels in rockets .It releases less pollutants and can reduce pollution. The only pollutant it release is Nitrogen , which can be minimized by injecting some water into it .Hydrogen is also used in fire extinguishers.

Right from the dresses we wear , food we eat .....everything is made up of carbon. Graphite and The hardest stone - diamond are the allotropes of carbon.The gas in our LPG also consists of the carbon compound.

Photosynthesis - The process which is solely responsible for the survival of mankind is not possible without elements as it involves the compounds of elements - oxygen , Hydrogen , carbon

When we get fever , we go to a doctor and he checks our temperature using a thermometer which is filled with the element mercury

Not only these ...There are so many uses of elements .So they do not cause us harm. But there are few elements like Beryllium , lead, uranium .... which cause harm to us .The same element which helps us in making balanced diet ( carbohydrates - carbon ) can also harm us when it is combined with oxygen ( carbon monoxide , Carbon dioxide ) to form acid rain, and green house effect.

'' Finally we conclude that many elements help us and a few harm us "
