Principal quantum number of an electron existing in such a stationary state is taken as, n = ∞. Such kind of hydrogen atom is called an ionised hydrogen atom. A negative sign is placed in the above equation as, due to the transition of an electron from one orbit to another, the stationary state energy is emitted and thus, energy is lowered.

In a phosphorus fertiliser, phosphorus is the principal nutrient. The effective phosphorus concentration, fertilisation techniques, soil characteristics, and crop strains all affect how successful a fertiliser is. The protoplasm of the cell contains phosphorus, which is crucial for cell growth and proliferation.

Let us take a look at how different dictionaries define a figure of speech to have a much better idea of what it is. Definition of a Figure of Speech A figure of speech, according to the Oxford Learner’s Dictionary, is defined as “a word or phrase used in a different way from its usual meaning in order to create a particular mental picture ...

One common thing is that they both contain the principal element known as sodium. As far as the physical appearance goes, both are white, they are usually solids but often found in powdered form. Further, both are classified as a base and these two also have ionic bonds. They occur naturally as compounds of sodium.

Dec 08, 2022 · The Economic and Social Council (ECOSOC) is one of the six principal organs of the United Nations. It is the main body responsible for coordination, policy dialogue, policy review and recommendations on social, economic and environmental issues, and also the implementation of internationally agreed development goals.

Principal quantum number; Azimuthal quantum number; Spin quantum number; The magnetic quantum number is the third on the list between spin and azimuthal quantum number. It splits the sub-shells (such as s,p,d,f) into individual orbitals and places the electron in one of them.

Define excretion. Name the excretory unit of a kidney. Answer. Excretion is the process of removal of waste products from the body. Nephrons are the excretory unit in kidney. ... Principal of dialysis: The procedure of dialysis is based on diffusion of solutes and ultrafiltration of fluid across a semi-permeable membrane. In dialysis, the blood ...

An object AB is held perpendicular to the principal axis at a distance beyond the focal length of the lens. A real, inverted magnified image A’B’ is formed as shown in the figure. From the given figure, we notice that ABO and A’B’O are similar.
