Why positive rays produce flashes on ZnS plates?
Positive rays produce flashes on ZnS plates because they ionize atoms in the ZnS crystal lattice, creating excited states. When these excited states return to their ground state, they release energy in the form of visible light, causing a flash to be observed on the plate.
How many photons are required to ionize atomic hydrogen?
Ionization energy and electron affinity for cations and anions, respectively.
How do you ionize 63Cu?
Copper-63 can be ionized by removing an electron from its outer shell, creating a Cu^+ ion. This can be achieved through methods such as electron bombardment or exposure to high-energy electromagnetic radiation.
What is ionization energy and which element has the lowest ionization energy?
The energy required for an element to ionize and helium has the lowest.
Why are energy levels of hydrogen atom less than zero?
This doesn't really mean the electron has negative energy or energy less than zero. It is merely a matter of convention and the way the energy equation is written. "Because it takes a minimum amount of energy, called the "ionization energy" to strip or ionize a bound electron from the Hydrogen atom, energy levels are usually referred to as being negative quantities. In both classical physics and quantum mechanics the absolute value of energy is irrelevant; only energy differences matter. It is convenient to say that when ionized the electron will have zero binding energy to the proton. With this convention, the different energy levels of a Hydrogen atom are given by the equation: E = - E (z)/n^2 (notice that negative sign in the equation) where E(z) = 13.6 eV (1 eV = 1.602×10-19 Joules) and n = 1,2,3… and so on so that the ground state has energy E1= -13.6 eV and the second energy level (the first excited state) has energy E2 = -13.6/4 eV = -3.4 eV." Simple as that.
How much energy is required to ionize a hydrogen atom containing an electron in the n4 level?
The energy required to ionize a hydrogen atom with an electron in the n4 level is 0.85 electron volts.
How much energy is required to ionize a hydrogen atom in its ground (or lowest energy) state?
Ionization energy is the minimum energy required to remove an electron from a ground state atom. According to the relationship developed by Neils Bohr, the total energy of an electron in a stable orbit of quantum number n is equal to En=-[Z2/n2].
What is the longest radiation wavelength that can be used to ionize the ground state hydrogen atom?
The longest radiation wavelength that can ionize the ground state hydrogen atom is in the ultraviolet range, around 91.2 nm. This is known as the Lyman limit, where the photon energy is just enough to ionize hydrogen by freeing the electron from its bound state.

Will an element having high electron affinity ionize easily?
It will not ionize ealily, high electronegativity willionize easily.

What is a high energy electron and how does it differ from low energy electrons in terms of their behavior and impact on various processes?
A high energy electron has more kinetic energy and moves faster than a low energy electron. This difference in energy levels affects their behavior and impact on processes. High energy electrons are more likely to participate in chemical reactions, ionize atoms, and cause damage to biological molecules. In contrast, low energy electrons are less reactive and tend to be more stable, playing a smaller role in these processes.

What happens when photon is absorbed by atom?
When a photon is absorbed by an atom, it can excite an electron to a higher energy level or even ionize the atom by completely removing an electron. This absorption of energy can cause the atom to undergo various processes such as fluorescence, photoelectric effect, or photoionization, depending on the energy of the photon and the characteristics of the atom.
Does it take more, less, or the same amount of energy to ionize a hydrogen atom compared to other elements?
It takes less energy to ionize a hydrogen atom compared to other elements.
