How would you write the equation of the electron affinity.
Interpretation: The equations for the given lists are to be stated. Concept introduction: Ionization energy is defined as the energy required in removing an electron from a neutral atom. Electron affinity is defined as the change of energy of a neutral atom when electron is added to that atom to form negative ion.
Consider the first ionization energy of neon and the electron affinity of fluorine. (a) Write equations, including electron configurations, for each process. (b) These two quantities have opposite signs. Which will be positive, and which will be negative? (c) Would you expect the magnitudes of these two quantities to be equal? If not, which one.

This affinity is known as the first electron affinity and these energies are negative. By convention, the negative sign shows a release of energy. However, more energy is required to add an electron to a negative ion which overwhelms any the release of energy from the electron attachment process. This affinity is known as the second electron affinity and these energies are positive.
By definition, the first ionization energy of an element is the energy needed to remove the outermost, or highest energy, electron from a neutral atom in the gas phase. The process by which the first ionization energy of hydrogen is measured would be represented by the following equation.

The electron affinity of an atom or molecule is defined as the amount of energy released when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion. It is the tendency of an atom to gain electron. It is numerically equal to the negative of electron gain enthalpy. Although fluorine has the highest electronegativity, chlorine has the highest electron.
Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.

See my edit: Maybe the first ionisation energy of Krypton isn't as large as the electron affinity of Fluorine? In simple terms, I reckon Krypton wants to keep its full outer shell, but Fluorine so desperately wants more electrons that it can take one from the outer shell of Krypton, where electrons are abundant.
This chapter discusses the history, abundance, distribution, and extraction of the halogens fluorine, chlorine, bromine, iodine, and astatine. The chapter highlights the fluorine technology and the applications of fluorine-containing compounds that have developed dramatically during the 20th century. The halogens do not occur in the free.
A good approximation of electron affinity is the energy of the LUMO (lowest unoccupied molecular orbital). Electron affinities follow the same trends as the ionization energy across the periodic table as seen below. The first of two main methods which scientists use to calculate the ionization energy is the Subtraction Method. This method.

You can think of the terms work function, electron affinity and ionisation potential as in a photo emission experiment on a semiconductor: The work function is the position of the Fermi level at.
The work function and electron affinity of fluorine-terminated (100) diamond surfaces prepared by exposure to dissociated XeF2 have been determined using synchrotron-based photoemission.
Electron affinity The energy released when an electron is added to the neutral atom and a negative ion is formed. Electronegativity (Pauling scale) The tendency of an atom to attract electrons towards itself, expressed on a relative scale. First ionisation energy The minimum energy required to remove an electron from a neutral atom in its.
