Does neon or chlorine have higher ionization energy?
Answer: Neon has a higher nuclear charge which makes its 1s orbital smaller than the 1s orbital for F. Br- should have a smaller ionization energy than Cl-.
Why is chlorine the highest electron affinity?
Chlorine has the highest electron affinity among the elements. Its high affinity can be attributed to its large atomic radius, or size. Because chlorine’s outermost orbital is 3p, its electrons have a large amount of space to share with an incoming electron.
Which is more electronegative chlorine or neon?
For example, in the hydrogen chloride molecule, chlorine is more electronegative than hydrogen by 0.96 electronegativity units….Periodic Trends — Electronegativity.

Why is neon not most electronegative?
No, neon gases aren’t included in electronegativity. This is because they’ve filled their valence shells so they don’t need to attract electrons and electronegativity is the ability of an atom to gain an electron.
Which is more active between chlorine and neon?
Chlorine is more reactive than Neon. According to octate rule the compounds having every atom tries to occupy the octate condition in which there are 8 electrons in its outer most shell. The outer most shell of the Chlorine contains the subshells with principal quantum number 3 which are 3s^2, 3p^5.
Will neon and chlorine react?
Neon is thought to be inert, unable to form neutral compounds. Some ions of neon have been observed to form compounds such as . So the answer is, nothing. Despite chlorine’s strong reactivity, neon will not form a compound with chlorine since neon is inert.
Why is chlorine larger than fluorine?
The fluoride ion has an extra electron compared to the fluorine atom, and electrons (being negative) repel each other. Since there are more electrons trying to keep away from each other, the ion is larger than the atom.
Why does chlorine have more electron gain enthalpy than fluorine?
It is due to small size of fluorine atom. As, there are strong inter electron repulsion in the relatively small 2P orbits of fluorine and thus, the incoming electron does not experience much attraction. Therefore chlorine has the electron gain enthalpy than the fluorine.
Why is chlorine more electronegative than sodium?
Chlorine is highly electronegative 3.5 and attracts electron to attain stability by completely filled valence shell . also it’s small nucleus and large size helps it to attract electron. Cl Z=17 valency 1. While sodium is an electropositive element and it prefers to give out electrons To become stable.
Why is chlorine more electronegative than phosphorus?
the electronegative elements have a tendency to gain electrons and hence they are anions. chlorine Phosphorus and sulphur are electronegative because they have a tendency to gain electrons from other elements during a chemical reaction. the highest electronegative element is fluorine.
Why fluorine is more reactive than chlorine?
Electronegativity is probably the biggest thing that plays into reactivity. Therefore, since fluorine has a higher electronegatvity than chlorine, fluorine is more reactive.
Why is the ionization energy of sodium less than neon?
Hence the ionization energy of sodium is LESS than that of neon meaning that it is easier to remove an electron from outermost shell of isolated sodium atom as compared to neon atom. Neon has 8 electrons in its outermost shell. All electrons are paired making it more stable.
Why does fluorine have a higher electronegativity than chlorine?
Therefore Fl has a higher ionization energy than Cl. If fluorine has greater electron shielding than that of chlorine, why is its electronegativity greater than chlorine’s if chlorine’s electron affinity is greater? The atomic radius of fluorine is smaller than the atomic radius of Cl.
Why does cesium have the lowest ionization energy?
It is because of the shielding effect that the ionization energy decreases from top to bottom within a group. From this trend, Cesium is said to have the lowest ionization energy and Fluorine is said to have the highest ionization energy (with the exception of Helium and Neon).
