Half Life Formula

Half Life Formula

Half Life Formula is a very important formula in subjects like Physics and Chemistry.

Chemistry is the branch of Science that examines the characteristics, constitution, and structure of substances (defined as elements and compounds), as well as the changes they undergo and the energy expended or consumed. Every substance, whether naturally occurring or artificially created, is made up of one or more of the hundred-odd species of atoms known as elements. Although these atoms are made up of more elementary particles, they are the fundamental building blocks of chemical substances; for example, there is no quantity of oxygen, mercury, or gold smaller than an atom of that substance. Chemistry is thus concerned with the properties of atoms and the laws governing their combinations, as well as how knowledge of these properties can be used to achieve specific goals.

The great challenge in Chemistry is to develop a coherent explanation for the complex behaviour of materials, including why they appear as they do, what gives them their enduring properties, and how interactions between different substances can result in the formation of new substances and the destruction of old ones. Chemists have struggled to develop theories of matter that satisfactorily explain both permanence and change since the first attempts to understand the material world in rational terms.

Chemistry is also concerned with the use of natural substances as well as the creation of artificial ones. Cooking, fermentation, glass making, and metallurgy are all chemical processes that have existed since the dawn of time. Today, the fruits of chemical technology include vinyl, Teflon, liquid crystals, semiconductors, and superconductors. The understanding of the marvellous and complex Chemistry of living organisms advanced dramatically in the twentieth century, and a molecular interpretation of health and disease holds great promise. Modern Chemistry investigates materials as small as single atoms and as large and complex as DNA (deoxyribonucleic acid), which contains millions of atoms, using increasingly sophisticated instruments. New substances can even be designed to have desired properties before being synthesised. The rate at which chemical knowledge is increasing is astounding. Over time, over 8,000,000 different chemical substances, both natural and man-made, have been identified and produced. As recently as 1965, the figure was less than 500,000.

Chemistry is very important for those students who have opted for Science in Class 11 and Class 12. Studying Chemistry will help them to score well in their Biology and Physics exams too as often the subjects are interconnected with each other. Students can study Chemistry with the help of the various resources provided by Extramarks. Extramarks provides study tools such as NCERT solutions, revision notes, and past years’ papers solutions for the benefit of students.

What is Half Life Formula?

The Half Life Formula is used to calculate the Half Life Formula of a substance whose quantity is decaying or decreasing. A decaying substance decays at a different rate for different quantities of the substance. The rate of decay slows as the quantity of the substance decreases, making it difficult to determine the life of a decaying substance. As a result, the Half Life Formula is employed to provide the appropriate metrics for defining the life of decaying material. Students would learn more about the Half Life Formula and solve some examples in this section.

Half Life Formula

Half Life Formula refers to the amount of time required for half of a specific sample to react, i.e. the time required for a particular quantity to reduce its initial value to half. The Half Life Formula is widely used in nuclear physics to describe the rate at which an atom decays radioactively. The Half Life Formula is obtained by dividing 0.693 by the constant. The disintegration or decay constant is referred to here.
