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)
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 can be said about the electron configurations of all the elements in a group?
The electron configurations of all the elements in a group have the same number of valence electrons. Valence electrons are the electrons found in the outermost shell of an element.
Why the elements of group 14 are most electronegative elemenets?
There is no Group 14. The elements of the group 7A are the most electronegative. Basically, electronegativity is the ability to attract electrons. Group 7A elements, or halogens, need just one more electron to reach stability, and are very reactive. So, they can easily accept that electron. In other words, their ability to attract electrons is the highest.
What is the number of valence electrons for the elements in group 1?
The elements in Group 1 have one valence electron in their outermost s orbital.
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)

Chlorine has the HIGHEST electron affinity on the periodic table.(Fluorine is an exception in this case.)
What is the trend in electron affinity of elements within a group?
decreases from top to bottom
Which element group have the most positive electron affinities?
The group that has a substantial affinity for electrons is group 17, the halogens. These elements have 7 valence electrons which makes them have the highest affinity for electrons.
What group of elements give off the most energy when they gain an electrons?
Group 8A, the noble gases because they have high electron affinity.
Why are group 7 and group 1 elements usually found as compounds?
These elements are highly unstable because of for group1- IP is low and for group 7 electron affinity is high
Halogen with the least-negative electron affinity?
The halogen with the least-negative electron affinity is astatine. Electron affinity and electronegativities decreases down a group. Since astatine is the last halogen located in Group 17 as you move down the column from fluorine, it has the least negative electron affinity.
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
Which element in Group 13 has the lowest electron affinity?
Polonium has the lowest electron affinity in the oxygen family.
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.
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 group of elements have stable electron confoguration?
The group of elements that have a stable electron configuration are the noble gases.
