What is the equation for the electron affinity of fluorine?
Therefore, the equation that correctly represents the electron affinity of fluorine is answer choice (C). F gas plus e minus forms F minus gas.
Why does F have a high electron affinity?
Due to fluorine's very small atomic radius, the space surrounding its nucleus is also very small, thereby increasing the attraction between the incoming electron and the fluorine nucleus–and, by extension, its electron affinity.
Is F electron negative affinity?
For example, when a fluorine atom in the gaseous state gains an electron to form F⁻(g), the associated energy change is -328 kJ/mol. Because this value is negative (energy is released), we say that the electron affinity of fluorine is favorable.
Does F or Cl have electron affinity?
Electronegativity of fluorine is greater than that of chlorine but electron affinity of chlorine is greater than that of fluorine.
How do you find electron affinity on the periodic table?
Patterns in Electron Affinity. Electron affinity increases upward for the groups and from left to right across periods of a periodic table because the electrons added to energy levels become closer to the nucleus, thus a stronger attraction between the nucleus and its electrons.

Is the fluorine has the highest electron affinity?
Fluorine has highest electron affinity in the periodic table.
Which has higher electron affinity fluorine?
Hence, we can conclude that in a period, fluorine (halogen) has higher electron affinity than neon (noble gas). Note: It is important to note that electron affinity is not the same as the electron gain enthalpy which is a change in enthalpy when a neutral atom gains an electron from outside.
Why does fluorine have lower electron affinity?
However, because fluorine is such a small atom, you are putting the new electron into a region of space already crowded with electrons and there is a significant amount of repulsion. This repulsion lessens the attraction the incoming electron feels and so lessens the electron affinity.
What is the first ionization energy of F?
1st–10th ionisation energies
| Number | Symbol | 1st |
|---|---|---|
| 9 | F | 1681.0 |
| 10 | Ne | 2080.7 |
| 11 | Na | 495.8 |
| 12 | Mg | 737.7 |
Which has highest electron affinity F or Cl?
Cl has higher affinity thanF because it can accommodate the incoming electron more easily thanF. F has small size and there will be repulsions for incoming electrons.
Does fluorine have high electron affinity?
Fluorine has highest electron affinity in the periodic table.
What is electron affinity of an element?
The electron affinity of an element is a measure of that element's tendency to act as an oxidizing agent (an electron acceptor) and is generally related to the nature of the chemical bonds the element forms with other elements.

Why does fluorine have a low electron affinity?
However, because fluorine is such a small atom, you are putting the new electron into a region of space already crowded with electrons and there is a significant amount of repulsion. This repulsion lessens the attraction the incoming electron feels and so lessens the electron affinity.
How do you determine electron affinity?
The amount of energy released when a neutral atom in its gaseous state accepts an electron and gets converted into a negatively charged ion is known as electron affinity. X ( g ) + e − → X − ( g ) + E . A . Therefore, the electron affinity of chlorine is – 349 KJ/mol.
Why is the electron affinity of F less than that of CL?
Electron affinity of fluorine is less than that of chlorine. This is due to the reason explained below: Fluorine has seven electrons in 2p-subshell whereas chlorine has seven electrons in its 3p-subshell. 3p-subshell is relatively larger than 2p-subshell.
Why does fluorine have a higher electron affinity than oxygen?
Further because F has 7 electrons and O has 6 electrons in the valence shell, therefore the tendency of F to acquire additional electron is higher than that of O, i.e., EA of F is higher than that O. In other words, EA decreases as F > O > N.
Which has higher ionization energy F or F2?
Overall, this distribution of electrons is, net, equivalent to having two electrons paired in a single bonding orbital. This also explains why the ionization energy of F2 is less than that of an F atom.
What is the electron affinity trend?
The electron affinity trend describes the trend across the periodic table and describes how much energy in an atom is released or spent when an electron is added to a neutral atom or the energy change that occurs when an electron is added to a neutral atom.
Which has more electron affinity F minus or CL minus?
Cl has higher electron affinity than F. On comparing chloride ion with fluoride ion we find that electron density per unit volume in fluoride ion (F−) is more than in chloride (Cl−) "ion. This means that coming electron in fluorine atom finds less attraction than in chlorine atom.
Which element has the highest electron affinity fluorine?
chlorine Halogens has higher electron affinity and it is supposed to be for fluorine, but chlorine has higher electron affinity than fluorine due to fluorine's smaller size. Hence, among given options chlorine has highest electron affinity.
How do you measure electron affinity?
The electron affinity is calculated by adding the energy gap and the ionization energy. However, the energy gap determined by PAS is often smaller than the actual energy gap by 0.2–1 eV, and difference is interpreted as the exciton binding energy (11, 12). Thus, the electron affinity is overestimated by PAS.
What is the reaction associated with ionization energy What is the reaction associated with electron affinity?
Chemical Bond Energy Considerations Ionization energy: the energy required to remove an electron from a neutral atom. Electron affinity: the energy change when a neutral atom attracts an electron to become a negative ion.

What is electron affinity on the periodic table?
Electron affinity (EA) or electron gain enthalpy or simply affinity in the periodic table defines the amount of energy released when an electron is added to an isolated neutral gaseous atom in its lowest energy level (ground state) to produce an anion.
Which has greater electron affinity fluorine or oxygen?
Electron affinity of oxygen is less than that of fluorine but greater than that of nitrogen.
Which has higher electron affinity fluorine or near?
Fluorine has highest electron affinity in the periodic table.
