which element would have a greater affinity for an additional electron Be or O?

What is energy released on adding an electron to an isolated gas phase atom?
All electron shells represent an energy level - it doesn't matter if its the outermost shell or not. In order for there to be a release of energy the electron has to be coming from a higher energy state. The only energy state higher than the outer-most electron shell would be a free electron. The only way an electron becomes a free electron is that sufficient was provided to lift it from what-ever electron shell (energy level) it was previously in to escape velocity. The energy that it then releases in returning is then this exact same amount of energy.
Which has more electron affinity between cl2 and f2?
The reason that the electron affinity is not as high as might otherwise be predicted for fluorine is that it is an extremely small atom, and so it's electron density is very high. Adding an additional electron is therefore not quite as favorable as for an element like chlorine where the electron density is slightly lower (due to electron-electron repulsion between the added electron and the other electrons in the electron cloud).
What is the equation for the electron affinity of Mg plus?
If you express your answer as a chemical equation with all forms given, you would get: Mg+(g) + e- -> Mg (g)
Would you expect nonmetals to have larger electron affinities than metals?
Yes. Non metals have larger electron affinity than metals as non metals accept electrons more easily than metals.

Is fluorine paramagnetic?
Fluorine gas is diamagnetic as there are no unpaired electrons A neutral atom of flurine would be paramagnetic as due to the presence of 1 unpaired electron in a 2p atomic orbital
What would be the electrical charge of fluorine atom that gained an electron?
It would be -1 because gaining an electron will create a negative charge. F has a high electron affinity and therefore becomes an F- ion quite readily.
How do you determine electron affinity?
Measure the equilibrium constant for the reaction of thermal electrons with a species at different temperatures. this has been done with an electron capture detector. another way to measure it is to make a negative ion and shine light on it and measure the energy of the electrons removed by this process Dr.Edward Chen
Which element would most likely have a positive electron affinity between Na Al Rb and Ar?
This element is rubidium.

What element has the most negative electron affinity Al Si S Cl?
The element with the greatest electronegativity in this scenario would be Cl or Chlorine.
Would you expect nonmetals to have larger electron affinities than metals?
Yes. Non metals have larger electron affinity than metals as non metals accept electrons more easily than metals.
Which element would most likely have a positive electron affinity element Na element Al element Rb or elemnt Ar?
which of these is an extensive property of a substance? is it color, hardness, malleability, or volume
Why is electron affinity expressed as a negative number while the ionization energy has a positive number in calculating the energy of ion pair formation?
when dealing with atomic chemistry in most cases a negative number indicate the gaining of at least one electron and a positive number indicate the loss of an electron. the definition of electron affinity in a nutshell is the ENERGY required to add an electron to in most cases the outermost shell, so the more electron you trying to add the higher the nergy and the more negative the number would be which would represent the amount of electron added eg.. if i want to add let say 2e- to a oxygen atom then the result would be O(g) + 2e- = O2-(g) also you can see that an anion is formed. on the other hand ionization energy is the somewhat the opposite, it is the removal of the most loosely held electron from a atom in the GASEOUS state forming cation in the end. eg.. Na(g) = Na+(g) + e- . Note that while ionization MUST be in the GASEOUS state electron affinity not necessarily have to. So dont used both terms as positive or negative loosely like that its just an indication of telling us what is going on whether the atom is loosing or gaining electron/s. hope this helps .
