What do you mean by Nuclear Columbic Barrier?
As we know that any positively charged particle like the alpha particle is positively charged , when approaches the nucleus, it gets repelled by the nucleus. This repulsive force between…
What do you mean by Radiation Chemistry?
Radiation chemistry is a branch of chemistry which is developed is recent years. Whenever a substance is exposed to extremely high radiations of energy like gamma rays, some reactions take…
What do you understand by Radiolysis of Water Vapour?
One of the best examples for understanding the concept of radiation chemistry is Radiolysis of Water Vapour using gamma radiations. Some of the major products of Radiolysis of Water Vapour…
How the ionic products are formed in the Radiolysis of Water Vapour?
Formation of ionic products: During Radiolysis of Water Vapour, some of the ionic products which are produced are as follows: γ + H2O ——> H2O* ——> H2O+ + 2e–——>e– +…
How the free radicals and molecular products are formed in the Radiolysis of Water Vapour?
Formation of free radicals: The ionic products which are formed during Radiolysis of Water Vapour are very reactive. So they get recombined to form free radicals. The formation of free…
What do you mean by Hydrated Electron?
Water when irradiated with x-rays or γ-rays results into the formation of high energy electrons. These high energy electrons are known as Hydrated Electron. During collisions these electrons lose some…
