Question

Give reason for the following
Sodium and potassium are stored in kerosene.

Answer 1

As we know that in chemistry, periodic tables play a vital role. In the periodic table there are totally $118$ elements. In the periodic table there are totally $18$ columns and $7$ rows. The columns are called groups. Hence, $18$ groups in the periodic table. The rows are called periods. Hence, totally $7$ period in the table. Each and every element having a specific symbol in the periodic table. Each element having a specific position in the periodic table, that position is dependent on the physical and chemical properties of the element.

Complete answer:
We need to know that the atomic symbol of sodium is $Na$. The atomic symbol of potassium is $K$.
Sodium and potassium are first group elements in the periodic table.
Both elements are pyrophoric in nature. It was easy to catch the fire. The reason for the fire is both the metals are oxidised in moisture. That is the reason, to prevent oxidation and catch the fire, we stored Sodium and potassium in kerosene.
According to the above discussion, we conclude sodium and potassium are stored in kerosene as the reason, to prevent oxidation and catch fire.

Note:
We have to remember that the atomic number of the atom is depend on the number
of protons or the number of electrons. The atomic number of the atom is equal to the number of protons or the number of the electrons. The mass number of the atom depends on the number of protons and the number of neutrons. The mass number of the atom is equal to the sum of the number of protons and the number of neutrons in the atom. The oxidation reaction means addition of oxygen or the removal of hydrogen or the loss of electrons. The reduction reaction means addition of hydrogen or the removal of oxygen or the gain of electrons.
