4.1eV [Margalith et al, Applied Physics Letters, Vol 74 (1999), p 3930]
electron affinity is the negative of electron gain enthalpy. for example, the electron gain enthalpy of fluorine is -328, and electron affinity is 328 which is -(-328)
Selenium has the greater electron affinity
It has High electron affinity.
chlorine has the highest electron affinity
Generally, electron affinity increases (becomes less negative) in groups/families moving from top to bottom.
Helium has no electron affinity.
Fluorine does not have the highest electron affinity it has highest electronegativity the highest electron affinity is for chlorine atom.
electron affinity is the negative of electron gain enthalpy. for example, the electron gain enthalpy of fluorine is -328, and electron affinity is 328 which is -(-328)
Bromine has a higher electron affinity.
Selenium has the greater electron affinity
chloline
It has High electron affinity.
Yes, that is part of the definition of electron affinity.
chlorine has the highest electron affinity
Generally, electron affinity increases (becomes less negative) in groups/families moving from top to bottom.
The energy change that occurs when an electron is added to a neutral atom. This is usually exothermic. Noble Gases are excluded from this. Equation: X(element)+e-(electron)---------> X-1+ energy
To create an electron affinity reactor you will have to use the second ionization energy.
