Why the electron affinity is important?
Electron affinity for an atom is important to make it as a molecule.where atom is a small single one and molecule is the combination of two or more atoms.electron affinity is just a desire for attraction of electron by the atom.for example : We should have some affection for others to become their close relation like friends and live together in the same way a single atom should have desire [that is framed as ELECTRON AFFINITY] for electrons to be attached to form molecule
What is beryllium's electron affinity?
It is NOT negative (for the first IE). Because Be's configuration is 1s2 2s2, we observe that it has no vacant orbital to accommodate an electron, meaning that to insert an electron, it has to go into a new sub-orbital, the higher-energy 2p. Hence, you need energy to promote this electron to a 2p level to force Be to accept it.
What element has 1 valence electron and 19 protons?
Potassium
How many electron shells does polonuim have?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
How many electron shells does gold atom have?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Which has higher electron affinity fluorine or chlorine?
Fluorine has higher electron affinity than any other element.
Which has a greater electron affinity fluorine or bromine?
Fluorine has greater electron affinity than bromine, or any other element.
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 in Group 13 has the lowest electron affinity?
Polonium has the lowest electron affinity in the oxygen family.
What element that increasing electron affinity?
rare earth elements
Is oxygen has more electron affinity than sulfur?
Yes. Oxygen has greater electron affinity than any other element except fluorine.
Which has lower electron affinity between oxygen and fluorine?
This element is fluorine.
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?
This element is rubidium.
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?
O because it is a 2-
which element would have a greater affinity for an additional electron Be or O?
Last time i cheacked it could be Be
