Introduction to Analytical Electron Microscopy
The birth of analytical electron microscopy (AEM) is somewhat obscure.Was it the recognition of the power and the development of STEM that signaled its birth?Was AEM born with the attachment of a crystal spectrometer to an otherwise conventional TEM? Or was it born earlier with the first analysis of electron loss spectra?It's not likely that any of these developments alone would have been sufficient and there have been many others (microdiffraction, EDS, microbeam fabrication, etc.) that could equally lay claim to being critical to the establishment of true AEM.It is probably more accurate to simply ascribe the present rapid development to the obvious: a combination of ideas whose time has come.Perhaps it is difficult to trace the birth of AEM simply because it remains a point of contention to even define its true scope.For example, the topics in this book, even though very broad, are still far from a complete description of what many call AEM.When electron beams interact with a solid it is well-known that a bewildering number of possible interactions follow.Analytical electron microscopy attempts to take full qualitative and quantitative advantage of as many of these interactions as possible while still preserving the capability of high resolution imaging.Although we restrict ourselves here to electron transparent films, much of what is described applies to thick specimens as well.Not surprisingly, signals from all possible interactions cannot yet (and probably never will) be attained simultaneously under optimum conditions.

What is the lost energy of an electron?
The lost energy of an electron refers to the energy that an electron loses when it moves from a higher energy level to a lower energy level within an atom. This lost energy is emitted in the form of a photon of light. The amount of lost energy is directly related to the difference in energy levels between the initial and final states of the electron. This phenomenon is known as electron transition or electron relaxation.
-
Why is ionization energy endothermic and electron affinity exothermic?
Ionization energy is endothermic because it requires energy to remove an electron from an atom, overcoming the attractive forces between the electron and the nucleus. This process requires an input of energy, making it endothermic. On the other hand, electron affinity is exothermic because it involves the release of energy when an electron is added to an atom, forming a negative ion. This process releases energy as the electron is attracted to the positively charged nucleus, making it exothermic.
-
How do you calculate the energy of an electron?
The energy of an electron can be calculated using the equation E = -13.6 eV/n^2, where E is the energy, n is the principal quantum number, and -13.6 eV is the energy of the electron in the first energy level. By plugging in the value of n for the specific energy level, the energy of the electron can be determined. This equation is derived from the Bohr model of the atom, which describes the energy levels of electrons in an atom.

What is a unbound electron and a free electron pair?
An unbound electron is an electron that is not associated with an atom or molecule, meaning it is free to move independently. A free electron pair refers to a pair of unbound electrons that are not part of a chemical bond and are free to move around. These free electrons play a crucial role in various physical and chemical processes, such as conductivity in metals and chemical reactions.

What is an unbound electron and a free electron pair?
An unbound electron is an electron that is not associated with an atom or molecule, meaning it is free to move independently. A free electron pair refers to two electrons that are not involved in bonding with other atoms, allowing them to move freely within a material. Both unbound electrons and free electron pairs play important roles in various physical and chemical processes, such as conducting electricity in metals or participating in chemical reactions.

Does a higher voltage also mean more energy per electron?
No, a higher voltage does not necessarily mean more energy per electron. Voltage is a measure of the electric potential difference between two points, while energy per electron is determined by the electron's charge and the potential difference it moves through. The energy per electron is calculated by multiplying the electron's charge by the voltage it moves through. So, while a higher voltage can result in more energy per electron, it is not the sole determining factor.

Do supplements slow down metabolism?
Supplements themselves do not slow down metabolism. In fact, some supplements like certain vitamins and minerals can support a healthy metabolism. However, it is important to note that some weight loss supplements or products marketed as metabolism boosters may not be effective or safe. It is always best to consult with a healthcare provider before taking any supplements to ensure they are appropriate for your individual needs and health goals.

When does electron absorption occur and when does electron emission occur?
Electron absorption occurs when an electron gains energy and moves to a higher energy level within an atom or molecule. This can happen when the electron absorbs a photon of light or heat energy. On the other hand, electron emission occurs when an electron loses energy and moves to a lower energy level, releasing a photon of light or heat energy in the process. This can happen when an electron is excited to a higher energy level and then returns to its original energy level.
