What element has the highest electron 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.
What does high electron affinity mean?
Based on this sign convention, this means that a higher electron affinity indicates that an atom more easily accepts electrons. A lower electron affinity indicates that an atom does not accept electrons as easily.
What is the electron affinity of a compound?
The electron affinity (Eea) of an atom or molecule is defined as the amount of energy released when an electron is attached to a neutral atom or molecule in the gaseous state to form an anion. In other words, the enthalpy change and the electron affinity differ by a negative sign. …
Which of the following has highest first electron affinity?
Among all the given options, F atom has the highest electron affinity. (But, Cl has the highest electron affinity in the periodic table, F being the second highest). 18.
Which has higher electron affinity fluorine or chlorine?
the electron affinity of the fluorine is less than chlorine because the size of fluorine is too small as size decreases from left to right inside period, whereas chlorine has a larger size to accommodate electrons hence electron affinity of chlorine is more than fluorine.
Which has higher electron affinity nitrogen or phosphorus?
Nitrogen has greater electron affinity than phosphorus .
Which group has the highest electron affinity within a period?
Electron affinity generally decreases going down a group and increases left to right across a period. Nonmetals tend to have the highest electron affinities.
Which has the higher electron affinity I or F?
Florine is the most electro-negative element, thus giving it the highest affinity to electrons.
Which has a higher EA fluorine or Neo?
=>Fluorine has higher electron affinity . Electron affinity increases as we move from left to right in a particular period . and we do not include neon (which is noble gas ) in the trends.
Which family has largest electron affinity?
Electron affinity is the energy released when an electron is added to a gaseous atom or ion. Electron affinity generally decreases going down a group and increases left to right across a period. Nonmetals tend to have the highest electron affinities.
