Down the group electron affinity decreases
Across a period electron affinity increases.
However, it should be noted that chlorine is having higher electron affinity than flourine due to the small size of fluorine atom)
The electron affinities of the elements in Group 17 are larger (more negative) than the elements in Group 1 and because Elements in Group 14 have larger (more negative) electron affinities than elements in Group 15.
As you go across a period; Left to right, the electron affinity increases. As you go down a group; top to bottom, the electron affinity decreases.
more negative across a period
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.
Generally it gets higher/stronger but there are exceptions.
Atomic size increases to the bottom left, and the following increase up and to the right with exceptions: Electronegativity Electron Affinity (Z-effective) Ionization Energy Elements to right have fuller valence shells, etc
Helium has no electron affinity.
Seasons: The changing of seasons, like summer, fall, winter, and spring, is a recurring pattern we encounter each year. Lunar cycles: The phases of the moon, such as full moon and new moon, occur in a regular cycle. Paychecks: For many people, receiving a paycheck on a bi-weekly or monthly basis is a periodic trend that impacts their financial planning.
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.
Atomic Radii,Ionic Radii, First Ionization Energy,Second and Higher Ionization Energies, Electron Affinity.
Yes, that is part of the definition of electron affinity.
