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.)
If an element has 1 valence electron what group is it in?
That element would be in the Alkali Metals (group one)
What element in group 2 is most likely to loose and electron?
radium as the ,negative, electrons in it's outer shell are least affected by the ,positive, nucleus.
Which statement best describe why the halogens in group 7a have such high electron affinities?
C. They gain electrons easily because they are just... that's enough for you to get if right

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.
Why do halogens in group 7 have such have such high electron affinities?
Because they only need 1 electron to get the inert/noble gas structure and thus be extremely stable.
Why do the halogens in group 7a have such high electron in affinities?
Mostly they are highly electronegative and they only need one electron to fill their outer shell in a noble gas octet configuration.

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.
What are the Every element in group one has one electron in its outer shell Every element in group two has two electrons in its outer shell?
Both statements are true:Every element in group I has one electron in its outer shell andEvery element in group II has two electrons in its outer shell
An element that has the electron configuration Ne3s23p5 is in which period?
It is in group 17.
How many valence electron does a group 18 element have?
8
