Why standard reduction potential of fluorine is greater than cl2?

Fluorine and chlorine both need to gain electrons in order to achieve a stable electron configuration of 8 electrons in their outer shell, but fluorine is the smaller atom. As atoms get larger, their ability to attract electrons is reduced and they become more metallic in nature and less nonmetallic, because the outer shells of the electrons are farther from the positively charged nucleus, and even though the nucleus of larger atoms also has a larger positive charge, the increase in charge has less effect than the increase in distance, because charge is a direct proportionality and distance is an inversely squared proportionality. Distance matters more. So fluorine has the greater attraction for electrons, or as you put it, it has the greater reduction potential.

Is 1 or negative 1 greater?
In standard mathematics, 1 is greater than -1. This is written as 1 > -1
Which has greater line capacity T1 or E1?
The E1 has a greater line capacity. E1 is the European standard and runs at 2.084 Mbps. The American T-1 standard runs at a capacity of 1.544 Mbps.
How do you write greater decimal in standard form two thousand and one millionth or ten thousand and one hundredth?
So the two numbers are 2000.000001 and 10000.01. 10000.01 is the greater and this is 1.000001x104 in standard form
What is the sample size for standard deviation?
There is no such thing. The standard error can be calculated for a sample of any size greater than 1.
How do you calculate mean and Median smaller then Standard deviation?
In the same way that you calculate mean and median that are greater than the standard deviation!
What is the relative standard reduction potential of the half-cell in which reduction occurs?
The relative standard reduction potential of a half-cell is a measure of the tendency of a species to gain electrons and undergo reduction. It is defined relative to a standard hydrogen electrode, which is assigned a potential of 0 V. The more positive the reduction potential, the greater the tendency for reduction to occur in that half-cell.
What pair of half-reacations would have a negative total reduction potential?
A pair of half-reactions with reduction potentials that differ in sign will result in a negative total reduction potential. For example, a half-reaction with a reduction potential of +0.8 V paired with a half-reaction with a reduction potential of -0.7 V would give a negative total reduction potential (+0.8 V - (-0.7 V) = +1.5 V).
Is the total reduction potential of a cell in which potassium (K) is reduced and copper (Cu) is oxidized?
-3.27V
Which pairs of half-reactions would have a negative total reduction potential?
Any pair of half-reactions where the reduction potential of the half-reaction being oxidized is greater than the reduction potential of the half-reaction being reduced will have a negative total reduction potential. This results in a thermodynamically unfavorable reaction.
What does reduction potential tell about the stability of an element?
Reduction potential indicates an element's tendency to gain electrons and undergo reduction. Elements with higher reduction potentials are more likely to be reduced and are considered more stable in their reduced form, while elements with lower reduction potentials are less stable and more likely to be oxidize or lose electrons.
What will form a spontaneous reaction between two elements?
The element with the greater reduction potential is the one that is reduced.
What forms a spontaneous redox reaction between two elements?
The element with the greater reduction potential is the one that is reduced.
Will form a spontanous redox reaction between two elements?
The element with the greater reduction potential is the one that is reduced.
Which has a greater attraction for electrons Fluorine or Oxygen?
when compared to oxygen, fluorine has greater electronegativity (greater attraction for shared pair of electrons).
Which has a greater electron affinity fluorine or bromine?
Fluorine has a greater electron affinity than bromine. This is because fluorine is the most electronegative element, meaning it has a stronger attraction for electrons compared to bromine.
What does a reduction potential chart show?
A reduction potential chart shows the tendency of a species to gain electrons and be reduced. It ranks different chemical species according to their ability to gain electrons, with more positive values indicating a greater tendency to be reduced. This can help predict which reactions are spontaneous and which direction a redox reaction will proceed.
Which has a greater atomic radius at atom of fluorine or an atom of beryllium?
An atom of fluorine
