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 no electron affinity?
Helium has no electron affinity.
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 berylliums atomic mass?
Berylium is a non metal element. Atomic mass of it is 9.
What is the difference between electron and elektron?
Elektron is the spelling for the Greek word meaning "amber". It originated as the namesake for the negatively charged subatomic particle known as the electron because of amber's affinity for developing a static charge when rubbed against certain materials, such as wool. In fact, while wool develops a positive charge (meaning it loses electrons) amber develops a negative charge by rubbing electrons off the wool.
What is a sentence with the word electron in it?
My butt is an electron
What element has no electron affinity?
Helium has no electron affinity.
Why would flurine have the highest electron affinity?
Fluorine does not have the highest electron affinity it has highest electronegativity the highest electron affinity is for chlorine atom.
What is the difference between electron affinity and electron gain enthalpy?
electron affinity is the negative of electron gain enthalpy. for example, the electron gain enthalpy of fluorine is -328, and electron affinity is 328 which is -(-328)
Which has higher electron affinity Iodine or bromine?
Bromine has a higher electron affinity.
Which has the lower electron affinity germanium or selenium?
Selenium has the greater electron affinity
What is an electron's electron affinity?
chloline
Does chlorine have a high electron affinity or a low ionization energy?
It has High electron affinity.
Does high value of electron affinity for an atom means that it will gain electron easily?
Yes, that is part of the definition of electron affinity.
What is the highest electron affinity?
chlorine has the highest electron affinity
Why is the electron affinity of Mg lower than the electron affinity of K?
Generally, electron affinity increases (becomes less negative) in groups/families moving from top to bottom.
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
How do you create an electron affinity reactor?
To create an electron affinity reactor you will have to use the second ionization energy.
