Group 8A the noble gasses because they have high electron affinity The elements of which group in the periodic table release the most energy by gaining an electron.

Most energy released by gaining an electron. If there is any noble gases in which you need to compare its electron affinity with other elements it will be dirt last. By definition the first ionization energy of an element is the energy needed to remove the outermost or highest energy electron from a neutral atom in the gas phase. Br S Ne most energy released by gaining an electron.

If you need to p. Basically the more electronegative an element is the higher electron affinity it has. The energy needed to remove one or more electrons from a neutral atom to form a positively charged ion is a physical property that influences the chemical behavior of the atom.

An electron absorb energy after a collision with a photon atom etc. Most energy absorbed by gaining an electron. The most electron affinity elements present in the periodic table are in group 18 or group 8A.

Equal charges repel opposite charges attract If a charge by itself moves when let go then it loses potential energy this potential energy will be turned into kinetic energy. Thus its BrPAr in accordance to most energy released by gaining an electronmost energy absorbed by gaining an electron. As a rule of thumb elements with highest electron affinity and electronegativity are up at the top right.

FREE Expert Solution Show answer. Which one of the following amongs each pair will release maximum energy on gaining one electron A F Cl B S Se C Li Na Prev Question Next Question 1 vote. Rank the following elements by electron affinity from most positive to most negative EA value.

First electron affinities have negative values. Elements x and y are from group 7 in the periodic table. Most energy absorbed by gaining an electron.

X is a liquid at rtp while y is a solid at rtp. Group 7A one away from being full. When electrons either absorb or release energy they do it by means of photons which can be thought of as little packets of electromagnetic energy.

97 264 ratings Problem Details. Why do atoms gain energy when they lose an electron and release energy when they gain an electron. Like other chemical reactions redox reactions involve a free energy change.

Arrange these elements based on electron affinity from most energy released by gaining an electron to most energy absorbed by gaining an electron. Rank these elements according to electron affinity from most energy released by gaining an electron to most energy absorbed by gaining an electron Si Kr Cl. Br S Ne most energy released by gaining an electron.

To rank items as equivalent overlap them. Concepts and reason Electron affinity is the one form of energy that is released when the neutral atom in a gaseous state converts to the negatively charged ion by taking an extra electron. Reactions that move the system from a higher to a lower energy state are spontaneous and release energy while those that do the opposite require an input of energy.

This means that more energy is released in the formation of a halide ion than for the anions of any other elements. In redox reactions energy is released when an electron loses potential energy as a result of the transfer. Completely filled and half-filled elements.

As the behavior of elements having electron affinity is to release electron to attain stable state or to release excess energy. The first electron affinity is the energy released when 1 mole of gaseous atoms each acquire an electron to form 1 mole of gaseous -1 ions. Most energy released by gaining an electron ____ ____ ____ Most energy absorbed by gaining an electron the elements are.

Be C and Br Question Arrange these elements according to electron affinity. 97 264 ratings FREE Expert Solution. The elements of the halogen group Group 17 gain electrons most readily as can be seen from their large negative electron affinities.

This supplementary energy isemitted later as a photon and the electron returns to its original state. Rank from most positive to most negative. Rank these elements according to electron affinity from most energy released by gaining an electron to most energy absorbed by gaining an electronSi Kr Cl.

These elements will gain the most energy while gaining an electron. What is the element that has an electron configuration of Ar 4s2 3d2. If a photon strikes an electron the electron.

It is the energy released per mole of X when this change happens. For example the first electron affinity of chlorine is -349 kJ mol -1. In short because the lowest energy states are the most stable and an atom bound to an electron is generally a lower-energy state than an atom separated from the electron since they attract eachother and you must add potential energy to the electron to strip it from the nucleus.
