From a purely electronegative standpoint, Flourine is most likely to be an electron acceptor.
OXYGEN because it has only one oxidation state of -2, all the other elements in the group have multiple oxidation states.
K potassium reacts readily with Cl chlorine because the electron configuration changes to that of a noble gas. Group 7a would be the best guess.
The Halogens Fluorine, Chlorine, Bromine, Iodine and Astatine
Among the naturally occurring elements, the most likely one would be cesium, the least electronegative of all elements. In practice, any of the other alkali metals and any of the alkaline earth metals would usually react readily with chlorine gas, as would many of the transition metals.
Chlorine will readily accept one electron to its outershell.
From a purely electronegative standpoint, Flourine is most likely to be an electron acceptor.
Fluorine is similar to chlorine.
Group I elements (that is alkali metals)
OXYGEN because it has only one oxidation state of -2, all the other elements in the group have multiple oxidation states.
Chlorine is a nonmetal. It is only one electron short of a noble gas electron configuration and is much more likely to abstract an electron from some other element than to donate one to some other element.
K potassium reacts readily with Cl chlorine because the electron configuration changes to that of a noble gas. Group 7a would be the best guess.
Elements in the 1st group have 1 valence electron. So they are likely to donate 1 electron to get more stable. potassium, rubidium and cesium are likely to donate 1 electron.
Nonmetals, expecially halogens.
The group 1 elements, which are the alkali metals.
chlorine or Cl
It depends which diagram, most likely they are electron shells as all elements have
