Question
Classify the elements based on their property of conductivity with suitable examples.

Answer

Elements can be classified into three categories on the basis of their conductivity :
(1) Metallic elements: They have high values of electrical conductivity.
For example, Copper (Cu), Aluminium (Al), Silver (Ag).
(2) Non-metallic elements: They have low values of electrical conductivity.
For example, Oxygen $\left( O _2\right)$, Nitrogen $\left( N _2\right)$, Chlorine $\left( Cl _2\right)$.
(3) Metalloids: The values of their electrical conductivity is lower than metals but higher than non-metals.
For example, Silicon (Si), Germanium (Ge).

Bharat was doing an experiment by using an ammeter. Suddenly, it fell from his hand and broke. He was afraid, that he might be scolded and threaten by his teacher. His classmate advised him not to tell the teacher, but he refused and told his teacher. On listening to him patiently, the teacher did not scold him and threaten as it was just an accident and used the opportunity to show the internal structure of the ammeter to the whole class.
On the basis of above passage, answer the following questions :
(1) What values do you learn from Bharat?
(2) What is the use of ammeter? How is it connected in the circuit?
(3) State the aim of any one experiment, where Bharat could have used the ammeter.
