Is an element with a large negative electron affinity most likely to form a positive ion a negative ion or a neutral atom?
An element with a large negative electron affinity is more likely to form a negative ion because it strongly attracts electrons to achieve a stable electron configuration. This results in the formation of negatively charged ions.
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 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.
What element has the most negative electron affinity Al Si S Cl?
Chlorine (Cl) has the most negative electron affinity among these elements. It has a higher tendency to gain an electron to form a chloride ion compared to aluminum (Al), silicon (Si), and sulfur (S).
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 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.

What element has no electron affinity?
Helium has no electron affinity.

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 can form both positive and negative ions?
Hydrogen is the element that can form both positive (H+) and negative (H-) ions. When hydrogen gains an electron, it forms a negative ion, and when it loses an electron, it forms a positive ion.
What is the electron affinity of yttrium?
The electron affinity of yttrium is 29.6 kilojoules per mole. This is how much energy this element releases when added to a single neutral, gaseous molecule or atom to create a negative ion.
What element has the most negative electron affinity Al Si S Cl?
Chlorine (Cl) has the most negative electron affinity among these elements. It has a higher tendency to gain an electron to form a chloride ion compared to aluminum (Al), silicon (Si), and sulfur (S).
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.
If an element is missing one electron... is it a positive ion negative ion different element or different isotope?
If an element is missing one electron, which is defined as having a negative charge, then the element is a positively charged ion. If an element gains an extra electron, it will have a negative charge and be a negative ion. An element with an equal number of positively charged protons and negatively charged electrons is considered to be a neutral element (in other words, no charge). By the way, no charge for this answer!
