Which has higher electron affinity Br or Cl?
Bromine is located below chlorine in group 17, which means that a bromine atom is larger than a chlorine atom. In other words, chlorine has a higher electron affinity than bromine.
Which element has highest value of electron affinity Cl Br Fi?
cl is the highest electron affinity.
Which has higher electron affinity Br or I?
A more negative electron affinity corresponds to a greater attraction for an electron. (An unbound electron has an energy of zero.)…Electron Affinity Trends.
| Element | Electron Affinity |
|---|---|
| I | -295.2 kJ/mole |
| Br | -324.5 kJ/mole |
| Cl | -348.7 kJ/mole |
| F* | -327.8 kJ/mole |
Which is the correct order of electron affinity A F Cl Br i’b o/s se te c/p n as SB d’i Br Cl F?
Electron affinity of Cl is greater than fluorine so the order is as F.
Why does Cl have 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 group has the highest electron affinity?
Atoms, such as Group 7 elements, whose anions are more stable than neutral atoms have a higher electron affinity. The electron affinities of the noble gases have not been conclusively measured, so they may or may not have slightly negative values. Chlorine has the highest electron affinity while mercury has the lowest.
Which of the following has the greatest e affinity * A I B Br C F D Cl?
Correct option d Cl Explanation:Due to smallest atomic sizes amongst the elements in their respective groups the elements of second period have lower electron affmities loweithan the corresponding elements of the third period. So chlorine has highest electron affinity.
What is the electron affinity of Cl?
-349 kJ mol-1
For example, the first electron affinity of chlorine is -349 kJ mol-1. By convention, the negative sign shows a release of energy. When an electron is added to a metal element, energy is needed to gain that electron (endothermic reaction).
Which has highest electron affinity?
Which Element Has 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.
Why does chlorine have the highest electron affinity?
Which of the following have highest electron affinity?
Fluorine has highest electron affinity in the periodic table.
How does chlorine have a higher electron affinity than fluorine?
Fluorine has seven electrons in 2p-subshell whereas chlorine has seven electrons in its 3p-subshell. Since, energy released during the formation of Cl− (g) ion is more than that released in case of F−(g) ion, the electron affinity of chlorine is more than that of fluorine.
What is electron affinity?
In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion. In other words, it can be expressed as the neutral atom’s likelihood of gaining an electron.
Why does chlorine and bromine have a positive electron affinity?
In order for an element to have a positive electron affinity, energy must be released when a mole of electrons is added to a mole of atoms in the gaseous state. The more energy is released when this happens, the more positive the electron affinity. As far as chlorine and bromine are concerned, your teacher is actually wrong.
What causes electron affinity to be positive or negative?
In order for an element to have a positive electron affinity, energy must be released when a mole of electrons is added to a mole of atoms in the gaseous state. The more energy is released when this happens, the more positive the electron affinity.
What is the electron affinity of argon?
It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity, behind only oxygen and fluorine. Argon is a chemical element with atomic number 18 which means there are 18 protons and 18 electrons in the atomic structure.
