electron affinity

The more tightly held an atoms valence electrons, the higher the electron affinity, correct?

Electron affinity values become more negative for atoms further to the right on the periodic table up until the noble gases. this is because the electron affinity tells you that it wants to add an electron. therefore, atoms with a filled outer subshell would have a lower affinity, whereas atoms which need one electron to fill their subshell would have a high affinity.

Non-metals and halogens have high electron afffinity because they want to form noble gas configuraiton by taking electron..on the other hand metals get to the noble gas configuration by loosing the electron so they have low electron affinity.. in short electron affinity is the love for electrons.. hope that helps you

Thanks, guys, I know that was kind of a dumb question, but I am just FREAKING OUT right now🙁

as you move right across the periodic table, electron affinity increases, because nonmetals accept electrons while metals lose electrons.....Thus, nonmetals have a greater "love" for electrons........The electron affinity is the energy with which the nucleus exerts a pull on the electrons, making it a part of its atom......

Since metals have a low affinity, they usually do not gain electrons..........the nuclear forces aren't strong enough to actually attract electrons from outside the atom........

Usually, atoms with a greater affinity have a higher electronegativity and will be smaller in size..

Hope this helps....

thats what i said.....

Someone should add that as people have described it in this thread, the phrase "electron affinity" is a synonym for electronegativity, which is probably the more commonly used term.

its not the same
ELECTRONEGITIVITY:A measure of the capacity of an element to compete for the shared electrons or more simply is a chemical property which describes the power of an atom (or, more rarely, a functional group) to attract electrons towards itself.

ELECTRON AFFINITY: the energy required to detach an electron from a singly charged negative ion, i.e., the energy change for the process or energy released when an electron is attached to a neutral atom or molecule
