What does the Saha equation show?
Saha equation, mathematical relationship between the observed spectra of stars and their temperatures. The equation was stated first in 1920 by the Indian astrophysicist Meghnad N. Saha. It expresses how the state of ionization of any particular element in a star changes with varying temperatures and pressures.
What is ionization reaction?
Ionization or ionisation is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes.
How is ionization achieved in field ionization?
A high electric field gradient (108 V/cm) at the tips of the whiskers produces ionization by quantum mechanical tunneling of electrons. FI is also used for performing isotope ratio measurements on samples that either give small molecular ions or large (M-H)+ ions in EI.
What is fab in mass spectrometry?
Fast atom bombardment (FAB) is an ionization technique used in mass spectrometry in which a beam of high energy atoms strikes a surface to create ions. When a beam of high energy ions is used instead of atoms (as in secondary ion mass spectrometry), the method is known as liquid secondary ion mass spectrometry (LSIMS).
Who worked on Sahas equation?
It was at this tender age of 26 that Meghnad Saha, who was working at Calcutta University far away from the world’s major centres of physics research and who never had a formal training from any research supervisor, formulated the celebrated Saha ionization equation and revolutionized astrophysics by applying it to …
Which physicist worked on Sahas equation?

What are the two ways to cause ionization?
Ionization can be induced by high energy radiation such as x rays and ultraviolet light (photoionization), bombardment by high energy electrons (electron impact ionization) or small molecular ions (chemical ionization) and by exposure to high electric fields (field ionization).
How do you balance NETnet ionic equations?
Net ionic equations must be balanced by both mass and charge. Balancing by mass means making sure that there are equal numbers of each element. Balancing by charge means making sure that the overall charge is the same on both sides of the equation. In the above equation, the overall charge is zero, or neutral, on both sides of the equation.
What is meant by ionization energy?
The energy essential to take away an electron from a gaseous atom A or a gaseous molecule AB is titled as ionization energy. Referring to the following equation.
How do you solve ionic equations step by step?
Step 1: Plan the problem . Write and balance the molecular equation first, making sure that all formulas are correct. Then write the ionic equation, showing all aqueous substances as ions. Carry through any coefficients. Finally, eliminate spectator ions and write the net ionic equation. Step 2: Solve .
What is the ionization energy of 3 moles of Al?
