What else can I help you with?
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.
Do nonmetals have always higher electron affinity than metals?
No, nonmetals do not always have higher electron affinity than metals. Electron affinity depends on the specific element and its position in the periodic table. Some metals can have higher electron affinities than certain nonmetals.
Why electron affinity increases from left to right in a period?
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.
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?
What are the general properties of the elements in the group on the right side of the periodic table?
The elements present at right side groups of the periodic table are non-metals. They have high electron affinity and ionization energy.
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.
Electron affinity tends to what?
Electron affinity is an elements' ability to attract electrons and is variable for each element. Generally the more electronegative atoms are furthest to the right bottom of the periodic table and ascending to the left the elements lose their electron accepting ability.
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.
How does electron affinity vary in periods?
Increases from left to right in a period
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 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)
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.
Do nonmetals have always higher electron affinity than metals?
No, nonmetals do not always have higher electron affinity than metals. Electron affinity depends on the specific element and its position in the periodic table. Some metals can have higher electron affinities than certain nonmetals.
Why does electron affinity tend to become more exothermic as you move right across a period?
Electron affinity tends to become more exothermic as you move right across a period because the effective nuclear charge increases, leading to a stronger attraction between the nucleus and the incoming electron. This results in a more stable electron configuration and a release of energy.
Differentiate the trends in periodic table?
Atomic size increases to the bottom left, and the following increase up and to the right with exceptions: Electronegativity Electron Affinity (Z-effective) Ionization Energy Elements to right have fuller valence shells, etc
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 element would most likely have a positive electron affinity between Na Al Rb and Ar?
Chlorine (Cl) would most likely have a positive electron affinity. Typically, elements with high electron affinities are found on the right side of the periodic table, closer to the noble gases. Among the choices given, Argon (Ar) is a noble gas and has a positive electron affinity.
