Generally electron affinity goes up as you go from left to right across the Periodic Table, and decreases as you go down a column.
There are exceptions however. See the Related Questions to the left for some examples of the exceptions as well as an explanation.

∙ 11y agoIf you were to attach a hydrogen to a fluorine and a nitogen making a CF and CN bond you would see that because fluorine is so small and electronegative, it is able to keep most of the e- close to it whereas Nitrogen is not as electronegative. Sorry to say but you just have to know that electronegativity increases as you go to the write

Is electron affinity of N is greater than F?
No, it is not. Electron affinity follows a trend like electronegativity and hence increases as we move from left to right across a period. So, Fluorine has the highest electron affinity among 1st period elements.
What happens when the nuclear charge increases across a period?
The atomic size decreases (with some exceptions) , the ionization energy , electronegativity and electron affinity also increase from left to right.
Why does electron affinity increase going left to right?
In general, electron affinity does not increase steadily from left to right. Firstly, only non-metals have electron affinities greater than 0. Secondly, the ordering of these electron affinities is O<N<F; S<P<Cl
How does ionization enthalpy vary as you move across the periods vary from left to right?
in a period size decreases from left to right and hence electrons are more tightly held to the nucleus. so electron gain enthalpy increases across a period . down the period size increases and thus in general electron gain enthalpy decreses .
What happens to electron affinity as you move down a group?
I would have to answer by asking about the ongoing line segment that joins the origin and a variable point in a system of polar or spherical coordinates. What is the length of a radius vector?
How does electron affinity vary in periods?
Increases from left to right in a period
What is the trend for electrons?
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.
Is electron affinity of N is greater than F?
No, it is not. Electron affinity follows a trend like electronegativity and hence increases as we move from left to right across a period. So, Fluorine has the highest electron affinity among 1st period elements.
What are the trends and exceptions to the trends in electron affinity?
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)
What happens when the nuclear charge increases across a period?
The atomic size decreases (with some exceptions) , the ionization energy , electronegativity and electron affinity also increase from left to right.
Which element has the lowest electron affinity Is it nitrogen?
No, nitrogen does not have a low electron affinity. Electron affinity increases as you go up and to the right on the periodic table. Thus, Groups I and II elements (ex. Cs, Ba, Sr, etc.) have LOW electron affinities and the halogens in Group VII (Br, Cl, F, etc) have the HIGHEST electron affinities. Chlorine has the HIGHEST electron affinity on the periodic table.(Fluorine is an exception in this case.)
What is electron affinity . write down its trend in periods and group?
The electronegativity increase in a period from left to right; in a group decrease by descending.
How would the tendency to lose electron change as you go from left to right across a periodic table of period?
The tendency to lose electron decreases along a period. The tendency to gain electron increases.
What periodic treds exist for ionization energy?
Ionization energy increases to the right and up on the periodic table. Ionization energy is the energy required to remove an electron. It can be conceptualized as the opposite of electron affinity, though this is not precisely true.
What are the acidity and basicity trends of the periodic table?
acidity increases from left to right and bottom to top in the periodic table. It follows the same trend as electron affinity and ionization energy. basicity follows the opposite trend. It increases right to left, top to bottom.
Atomic size generally as you go down a group?
Atomic size generally increases as you go down a group
Why does electron affinity increase going left to right?
In general, electron affinity does not increase steadily from left to right. Firstly, only non-metals have electron affinities greater than 0. Secondly, the ordering of these electron affinities is O<N<F; S<P<Cl
