Which has higher electron affinity carbon or oxygen?

It is observed that the electron affinity increases across a period. This is because there is an increase in nuclear charge which is a deciding factor for calculating electron affinity. Keeping the above point in mind we can easily say that carbon has least electron affinity and oxygen the most.

What element has highest affinity?

Chlorine
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 has greater affinity for oxygen?

Fetal Hb also has more affinity for oxygen than adult Hb. P50 ( partial pressure at which the hemoglobin molecule is half saturated with O2) for fetal Hb is 19 whereas P50 of adult Hb is 27.

Does carbon have a high electron affinity?

Electron affinity decreases or increases across a period depending on electronic configuration. Since a half-filled “p” subshell is more stable, carbon has a greater affinity for an electron than nitrogen.

Which is more negative oxygen or carbon?

Electronegativity is one of the most useful concepts in chemistry. In carbonyl group, oxygen is more electronegative than carbon and hence the bonding electrons are attracted more towards oxygen. This creates the partial negative and positive charges on oxygen and carbon respectively.

Why does fluorine have the highest electron affinity?

The incoming electron is going to be closer to the nucleus in fluorine than in any other of these elements, so you would expect a high value of electron affinity.

Why does fluorine have a higher electron affinity than oxygen?

This also explains why fluorine has a larger electron affinity than oxygen, as the electron brought in from the environment is being added to the 2pz orbital of fluorine which is closer to the nucleus (than the outer orbital of an oxygen atom) at a lower energy level where it becomes the outermost electron of the F- …

Which has more affinity for haemoglobin oxygen or carbon dioxide?

Haemoglobin has less affinity for Carbon dioxide as compared to oxygen because Carbon dioxide is a larger molecule than oxygen. Thus Carbon monoxide has the highest affinity with haemoglobin as compared with oxygen, carbon dioxide and ammonia. Hence, The correct answer is, option (A).

Does oxygen have a high electron affinity?

The second electron affinity of oxygen is particularly high because the electron is being forced into a small, very electron-dense space.

Which element has a lower in oxygen or carbon?

Well, basically because oxygen has a larger nuclear charge than carbon: i.e. Zoxygen>Zcarbon , where Z is the atomic number.
