What is the basic difference between electron gain enthalpy and electronegativity?
Ionization energy is the energy needed to remove an electron from an element, whereas electron affinity is the amount of attraction a substance has for a electron. One is the amount of energy to remove an electron while the other is the likeliness for it to attract an electron.
What prevent an element in a covalent compound from taking away another element valence electron?
This all has to do with the difference in electronegativity between the two atoms. The electronegativity is a measure of how strongly an atom attracts electrons. If they both attract electrons with about the same affinity (not a big difference in electronegativity), then you have a covalent bond, and they SHARE the electron(s) equally or almost equally.
Which has higher electron affinity fluorine or chlorine?
Fluorine has higher electron affinity than any other element.
The electron affinity of an atom typically depends on?
The electron affinity (or electronegativity as it would more usually be called) of an atom typically depends on the number of electrons in the outer shell. It is also influenced by the size of the atom. One electron in the outer shell gives you a low electronegativity, and seven electrons in the outer shell gives a high electronegativity; eight gives zero electronegativity. And as atoms get larger, the electronegativity falls off. So the very highest electronegativity is for the fluorine atom which is the smallest atom that has seven electrons in its outer shell.
Which energy is the energy that can be taken to remove an electron form its shell?
This energy is called ionization energy and is different for each chemical element.
What conclusion can be drawn from the statement that an element has high electron affinity high electronegativity and a high ionization energy?
This element is a very reactive nonmetal as fluorine or chlorine.
Will an element having high electron affinity ionize easily?
It will not ionize ealily, high electronegativity willionize easily.
What element has no electron affinity?
Helium has no electron affinity.
What element has the most negative electron affinity Al Si S Cl?
The element with the greatest electronegativity in this scenario would be Cl or Chlorine.
What determines the chemical reactivity or an element?
The higher the electronegativity of an element, the more reactive it is. Electronegativity is determined by the atomic number of an element, and the distance from the nucleus of the outer electron shell. The further from the nucleus an outer electron is, the easier it is to break its attraction to the atomic nucleus, and thus, the greater the element's propensity for forming molecular bonds. This answer is faulty since elements like Cesium are incredibly reactive, but have very low electronegativity and very low ionization energy, the energy to remove electrons. Because of that, elements at the top right and bottom left of the periodic table are both very reactive.
Why is an element with high ionization energy likely to have high electron affinity?
you can think of it like a magnet.A magnet with a peice of metal stuck to it.The harder it is to pull a peice of metal away from it (ionization energy), that means that it has more pull on the metal and will pull peices of metal with more force(electron affinity).
What is the basic difference between electron gain enthalpy and electronegativity?
Ionization energy is the energy needed to remove an electron from an element, whereas electron affinity is the amount of attraction a substance has for a electron. One is the amount of energy to remove an electron while the other is the likeliness for it to attract an electron.
Why does chlorine have more electron affinity than fluorine although it is below fluorine in periodic table?
Generally electron affinity goes up as you go from left to right across the periodic table, and decreases as you go down a column. However, fluorine is an exception -- and the element with the highest electron affinity is chlorine.(Note that the most electronegative element is fluorine however; 'electronegativity' is not exactly the same as 'electron affinity'.)Electronegativity is the ability of an atom in a molecule to draw bonding electrons to itselfElectron affinity is a measure of the energy change when an electron is added to a neutral atom to form a negative ion.The reason that the electron affinity is not as high as might otherwise be predicted for fluorine, is that it is an extremely small atom, and so it's electron density is very high. Adding an additional electron is therefore not quite as favorable as for an element like chlorine where the electron density is slightly lower (due to electron-electron repulsion between the added electron and the other electrons in the electron cloud).

This all has to do with the difference in electronegativity between the two atoms. The electronegativity is a measure of how strongly an atom attracts electrons. If they both attract electrons with about the same affinity (not a big difference in electronegativity), then you have a covalent bond, and they SHARE the electron(s) equally or almost equally.
How is the chemical symbol of an element determined-?
Usually the first and second letter of element can determine it's chemical symbol.
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.
