Characteristics of α-radiation, β-radiation and γ-radiation

by

A) α-radiation The α-rays are not rays, but consist of a stream of positively charged particles, having 2 units of positive (+) charge, and 4 units of mass. Thus, α-particles are doubly ionized helium atoms i.e., He2+. The α-particles emitted by any radioactive source are shot out with high velocity. The initial velocity depends on … Read more

Types of heat of reactions (enthalpies)

by

When the reactants of a chemical reaction are completely reacted to form products, then the heat evolved or absorbed is called the heat of reactions. Heat of reactions are of various types depending upon the nature of reaction. It must be defined for one mole. The various types of heat of reactions are as follows: … Read more
