What is the order of electron affinity in periodic table?
Hence, The correct order of electron affinity is $ O < Se < S $ .
What is the increasing order of electron affinity?
N < O .
What is the order of decreasing electron affinity?
In order of decreasing electron affinities, the elements are F, O,C, Li, Na, and Rb.
Which has highest electron affinity?
Chlorine
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.
What is the electron affinity order of Group 16?
Elements
| Z | Element | Electron affinity (eV) |
|---|---|---|
| 15 | P | 0.746 609(11) |
| 16 | 32S | 2.077 104 2(6) |
| 16 | 34S | 2.077 104 5(12) |
| 17 | Cl | 3.612 725(28) |
What is the correct order of electron affinity of Group 16 elements?
O.
Why 1st electron affinity is negative and 2nd is positive?
First electron affinities are typically negative values. This is because when an electron is added to a neutral atom, energy is released in an exothermic process. The second electron affinity is a positive value as energy is needed to add a second electron to an ion with a pre-existing negative charge.
What has the lowest electron affinity?
mercury
What is the lowest electron affinity? Metals are more likely to lose electrons than they are to gain them. Of the metals, mercury has the lowest electron affinity.
What is favorable electron affinity?
Electron affinity (the energy associated with forming an anion) is more favorable (exothermic) when electrons are placed into lower energy orbitals, closer to the nucleus. Therefore, electron affinity becomes increasingly negative as we move left to right across the periodic table and decreases as we move down a group.
What is the order of first electron affinity of o/s se?
Se > O > S.
