Question

Sodium is more likely to exist as a cation compared to chlorine for several reasons. Which of the following statements best explains this difference?
a) Chlorine is a gas, while sodium is a solid.
b) Chlorine has a greater electron affinity than sodium.
c) Chlorine is larger than sodium.
d) Chlorine has a greater ionization energy than sodium.
e) Chlorine is more metallic than sodium.

Option (d) chlorine has a greater ionization energy than sodiumExplanation:Ionization energy is the energy required to remove an electron from a gaseous atom or ion. Sodium has just 1 electron in it's outmost shell and chlorine has 7.Sodium needs 7 electrons to complete it's octet configuration and chlorine needs just 1. Sodium can not attract 7 electrons to complete it's octet configuration instead it will easily lose the 1 electron in it's outmost shell to form cation. On the other hand, it will be difficult for chlorine to lose any of it's outmost electrons. This makes chlorine to have higher ionization energy than sodium.

(D) chlorine has a greater ionization energy than sodiumExplanation:Sodium is the element of the group 1 and period 3 which means that the valence electronic configuration is .Chlorine is the element of the group 17 and period 3 which means that the valence electronic configuration is . Ionization energy is the minimum amount of energy which is required to knock out the loosely bound valence electron from the isolated gaseous atom.Thus, removal of one electron in sodium is easy as it will gain noble gas configuration and become stable. But this case does not exist in chlorine and hence, chlorine has a greater ionization energy than sodium.So, Sodium is much more apt to exist as a cation than chlorine because chlorine has a greater ionization energy than sodium.

A. Large atoms have valence electrons farther from the nucleus and lose them more readily, so they are more reactive than small atoms.For example, the valence electron of a small atom like Li is tightly held. Lithium gently fizzes on the surface as it reacts with the water to produce hydrogen.In contrast, the valence electron of a large atom like Cs is so loosely held that cesium exlodes on contact with water.

Mr. Madyson Huels Jr. · Answer

A. Large atoms have valence electrons farther from the nucleus and lose them more readilyExplanation:Large atoms have more energy levels, and the valence electron is farther from the nucleus, so the attractive force between this electron and the nucleus is weak. It will be necessary less energy for this atom loses an electron than a smaller atom. Large atoms lose their electrons more readily.

C ,  Large atoms have a greater number of electrons that they can lose during a reaction.

Number 1. The effective nuclear change of oxygen is greater that of fluorine.

Correct answers are- Electron affinity decreases; Cl has 7 valence electrons but Na has only 1. So Na is going to lose its e, Cl is going to gain an e.
