Is the electron affinity of germanium high or low?

The electron affinity of germanium is considered to be moderate. Germanium is a metalloid element with an electron affinity that falls between that of metals and nonmetals.


Which has higher electron affinity fluorine or chlorine?

Fluorine has higher electron affinity than any other element.


Is the electron affinity of an element positive or negative?

The electron affinity of an element can be either positive or negative, depending on whether the element tends to gain or lose electrons when forming chemical bonds.

rare earth elements


Which has a greater electron affinity fluorine or bromine?

Fluorine has greater electron affinity than bromine, or any other element.


What is the highest electron affinity?

chlorine has the highest electron affinity


Which element in Group 13 has the lowest electron affinity?

Aluminum has the lowest electron affinity in Group 13 because it is the most electropositive element in this group due to its position in the periodic table. Electropositive elements tend to have lower electron affinities.


What is the meaning of a negative value for the electron affinity of an atom?

Electron affinity is the amount of energy required to remove an electron from an atom. Or an energy released by adding an electron to a gaseous atom ( ie, negative quantity). In this case, if an element has a negative Electron Affinity, its indicating that this element is stable than the neutral ones.


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.)


Which element has a negative electron affinity. Is it Kr. O. Ca. He or Mg?

Helium (He) is the element that has a negative electron affinity. This means that it is less likely to gain an electron compared to other elements listed (Kr, O, Ca, and Mg) which have positive electron affinities.


Definition of electron affinity?

The energy change that occurs when an electron is added to a neutral atom. This is usually exothermic. Noble Gases are excluded from this. Equation: X(element)+e-(electron)---------> X-1+ energy


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.
