Which element group have the most negative electron affinities?
Fluorine flourine is the most electronegative element
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 group NORMALLY bonds with halogens?
Group 1 Alkali metals because the halogens need one electron to fill their outer electron shell.
Which elements have electron configurations that end in ns2np5?
halogens
Which elements have electron configuration that end in ns2 np5?
halogens
Which element group have the most negative electron affinities?
Fluorine flourine is the most electronegative element
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.
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.
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 characteristic about the outer electron shells of the halogens?
The outer electron shells of the halogens contain seven electrons, and need one more electron to have eight and become stable.
How are halogens like metals?
Halogens are not like metals. Halogens are elements missing one electron for full valency.
What group achieves the electron configuration of a noble gas by gaining one electron?
All halogens have 7 valence electrons. They gain one electron and achieve noble gas electronic configuration
What does not have identical outer electron configuration?
halogens
What group NORMALLY bonds with halogens?
Group 1 Alkali metals because the halogens need one electron to fill their outer electron shell.
Which elements have electron configurations that end in ns2np5?
halogens
Which elements have electron configuration that end in ns2 np5?
halogens
