The uses of the elements in our life depend on their properties . The elements are very important in our life , And we use them in many applications .
The uses of some elements
Sodium is a metal , and it is a good conductor of heat , It is used in liquid state in transferring the heat from inside the nuclear reactor to outside . This heat is used to obtain the vapour energy required to generate the electricity .
Radioactive cobalt 60 is used in the food preservation , because it radiates the gamma rays which prevent the reproduction of the microbial cells , but they do not harm the human .
Silicon is a metalloid . The silicon slides are used in the manufacture of the electronic devices such as the computer , Because Silicon is a semi-conductor and its ability to conduct the electricity depends on the temperature .
We can get rid of the gases of the undesirable odours inside the refrigerator by using a piece of coal which collects the gases on its surface .
