ok, so electron affinity is the amount of energy given off when a particular atom excepts electrons. Essentially, it is the likelihood that an atom will accept an electron, while ionization energy is how much energy is needed to take an electron off of a particular atom

What is the electron negativity difference between calcium and fluorine in calcium fluoride?
The Pauling electronegativity of calcium is 1,00.The Pauling electronegativity of fluorine is 3,98.
Is there a correlation of electron affinities to atomic radii?
The relation between electron affinity and atomic radius is inversely proportional.
What prevent an element in a covalent compound from taking away another element valence electron?
This all has to do with the difference in electronegativity between the two atoms. The electronegativity is a measure of how strongly an atom attracts electrons. If they both attract electrons with about the same affinity (not a big difference in electronegativity), then you have a covalent bond, and they SHARE the electron(s) equally or almost equally.
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 relationship between the ionization energy of a mono anion such as Cl and the electron affinity of the neutral atom?
This quantities have the same magnitude but opposite sign.

What is the difference between electron affinity and electron gain enthalpy?
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)
What elements has the largest electron affinity?
AnswerElectron affinity is the energy released when we add an electron to the outermost orbit of the atom. Halogens are the higher in electron affinity, and chlorine has the higher electron affinity than rest of the halogens. The irregularity in the electron affinity trend between Cl and F is due to the small size of the F atom. Although F definitely has a higher attraction for an electron than Cl (as evidenced by its high electro negativity value), the small size of the F atom means that adding an electron creates significant repulsion. Since electron affinity is an energy measurement, the total energy associated with electron affinity winds up being the energy that is released by the electron binding to the nucleus, minus the energy involved in overcoming the electrical repulsion in the outer shell.This makes the fluoride anion so formed unstable due to a very high charge/mass ratio. Also, fluorine has no d electrons which limits its atomic size. As a result, fluorine has an electron affinity less than that of chlorine.

Which has lower electron affinity between oxygen and fluorine?
This element is fluorine.
Is there a correlation of electron affinities to atomic radii?
The relation between electron affinity and atomic radius is inversely proportional.
What is the difference between emulsoid and suspensoid in terms of affinity for solvent?
The difference between emulsoid and suspension in terms of affinity for solvent is that suspensoids have no affinity for the solvent. They are ready to fall out as soon as a charge is dispensed into the medium.
Ionic bonds are between?
They are between two atoms.These atoms have high electro negativity difference
Who has higher electron affinity between bromine and Iodine?
According to Zumdahl, Group 7A elements (halogens) follow the expected behavior or periodicity as you follow top to bottom. The numbers (top to bottom) are getting closer to 0, so they are decreasing in electron affinity. Bromine has a higher negative # therefore it is a higher electron affinity.---papajohn
Why does chlorine have more electron affinity than fluorine although it is below fluorine in periodic table?
Generally electron affinity goes up as you go from left to right across the periodic table, and decreases as you go down a column. However, fluorine is an exception -- and the element with the highest electron affinity is chlorine.(Note that the most electronegative element is fluorine however; 'electronegativity' is not exactly the same as 'electron affinity'.)Electronegativity is the ability of an atom in a molecule to draw bonding electrons to itselfElectron affinity is a measure of the energy change when an electron is added to a neutral atom to form a negative ion.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).
Which increases as the electro negativity difference between 2 atoms increases?
Covalent nature of the bond
How the elements of the periodic table form compound?
By Bond ====> there are many types of Bond as ( Ionic , Covalent , Metallic , hydrogen Bond , Coordinate bond ,......) in ionic it almost between element whose electro negativity Difference more than 1.7 Like Na-Cl Sodium lose electron an change into +ve ion while Chlorine will gain this electron Then the force of attraction between +ve ion And negative ion making the bond and the ionic bond almost between metal and non metal in covalent bond almost between two non metal and electro negativity difference between them less than 1.7 as each element share an electron and the atom of higher electro negativity we have -ve partial charge and atom of higher electro negativity will have +ve partial charge and then the attraction force arise between them while the electron cloud rotate around them with different time around each one . in metallic is between metals as in Sodium metal each atom share an electron making electron cloud around them , hydrogen bond is between water molecule and etc....... different types of bonding
