Question

1. Which group of elements is stored in oil due to their reactive nature with water and air?

2. Waht is deterioration of a metal by chemical or electrochemical reaction with its environment called?

Answer 1

Dear student,

1. The Group 1 elements in the Periodic Table are known as the alkali metals. They include lithium, sodium and potassium, which all react vigorously with air and water. So FIRST GROUP ELEMENTS OF PERIODIC TABLE is stored in oil due to their reactive nature with water and air

2. The process whereby a material breaks into its constituent atoms because of the chemical reactions with its surrounding is called Corrosion. Rusting of a metal is a commonly known type of electrochemical corrosion. In rusting, the metal actually undergoes electrochemical oxidation with oxygen as an oxidant. The metal oxide (rust) is then formed. This metal oxide (rust) is the damage that is of serious concern to most industries all over the world.
