Properties and uses of some elements in the modern periodic table
The elements
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 a 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 electricity.
Nitrogen gas is a non-metal element, The liquified nitrogen is used in the preservation of the cornea of the eye, due to the decrease of its boiling point.
Radioactive cobalt 60 is used in food preservation, because it radiates gamma rays which prevent the reproduction of the microbial cells, but they do not harm the human.
Electronic slide
Silicon is a metalloid. Silicon slides are used in the manufacture of electronic devices such as computers, Because Silicon is a semiconductor, and its ability to conduct 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 that collects the gases on its surface.
