Question

Name the elements having the symbols: $Au,Pb,Sn,Mn,Sr\,and\,Si$ .

Answer 1

Hint: The given elements are used vividly in our daily life. $Au$ is used in jewellery, $Pb$ is used in the electrical industry, $Sn$ is used in industrial processes, $Mn$ is used to harden steel, $Sr$ is used in fireworks and $Si$ is used in making many alloys and best alloys.

Complete answer:
This periodic table is further divided into periods and groups. There are 7 periods and 18 groups. Period is the horizontal row on the periodic table. As we go along the group starting from the first period, we observe that the number of electrons increases. Therefore, from the left to write the number of electrons. Egg hydrogen has more electrons from helium, hydrogen has one and helium has two.
 In this periodic element all the elements in their increasing order of electrons are placed and given names according to their physical characteristics or the scientist who discovered it.
The name of an element with the chemical symbol $Au$ is Gold.
The name of an element with chemical symbol $Pb$ is Lead.
The name of an element with the chemical symbol $Sn$ is Tin.
The name of an element with chemical symbol $Mn$ is Manganese
The name of an element with chemical symbol $Sr$ is Strontium.
The name of an element with chemical symbol $Si$ is Silicon.

Note:
The atomic number of these elements are the number of electrons in their outermost shell which will always be equal to the number of protons in the nucleus of the element. These elements are used very vigorously in the industry, which also causes a lot of people to come into it. These mineral ores miners face a lot of respiratory and health problems in the long run without any compensation.
