Electron affinity trend
can someone explain what is the electron affinity trend on the periodic table? When we say it increases across a row, is it increasing in magnitude?

Re: Electron affinity trend
Electron affinity is the amount of energy released when an electron is added to an atom to form a negative ion. It does increase in magnitude as we move right across a row, but decreases as we move down a column.

Re: Electron affinity trend
Yes like the previous post said, electron affinity is the degree to which an atom or molecule attracts additional electrons. This affinity for electrons does increase moving right across a row and decreases down a column.

Re: Electron affinity trend
Electron affinity is the change in energy as an electron is added to a neutral molecule (in gas phase). The trend increases across the row and down the period.

Re: Electron affinity trend
Electron affinity essentially increases because we are adding electrons to energy levels leading to the nucleus drawing in those electrons more tightly. This is why it increases across a row seeing as the atomic radius decreases meaning the electrons are also closer to the nucleus.
Re: Electron affinity trend
Electron affinity increases up and to the right of the periodic table meaning that the most element with the most electron affinity would be fluorine.

Re: Electron affinity trend
Electron affinity increases across the period and increases up a group so the trend is increasing to the top right of the periodic table. Groups 16 and 17 have high electron affinities because the groups wants electrons to be a noble gas.

Re: Electron affinity trend
The electron affinity increases across to the right and up because elements are adding more electrons resulting in a electrons being more closely packed.

Re: Electron affinity trend
Electron affinity is the energy released when electron is added so it increases across.

Re: Electron affinity trend
Electron affinity increases going up and to the right of the Periodic Table, making the most electronegative atom Fluorine
