Hello. My question is essentially the title. My reasoning as to why electron gain enthalpy should be positive is that upon losing an electron, a group 1 atom will reach a noble gas configuration, as opposed to having 2 electrons in its outer shell if it gains an electron. Of course, ga...
Electron Gain Enthalpies of the Group 16 Elements As the size of the atom increases, the electron gain enthalpy decreases. Therefore, the electron gain enthalpies of the chalcogens decrease down the group. It is important to note that oxygen has a less negative electron gain enthalpy when compar...
Define Electron gain enthalpy. Electron gain enthalpy synonyms, Electron gain enthalpy pronunciation, Electron gain enthalpy translation, English dictionary definition of Electron gain enthalpy. n a measure of the ability of an atom or molecule to form a
What Are The Difference Of Modern periodic table, Electron Gain Enthalpy, negative electron gain enthalpy. Variation of electron gain enthalpy in group and period
Electron Gain Enthalpy When electrons are introduced into the valence shell of an atom, the electron is stabilized as it is entering the attractive positive electric field of the atomic nucleus. The electron loses energy and this...
Question 7.19:Knowing the electron gain enthalpy values for O → O- and O - O2- as -141and 702 kJ mol-1 respectively, how can you account for the formation of a large number of oxides having O2- species and not O-?(Hint: Consider lattice energy factor in the formation of compounds)...
2. Understanding Electron Gain Enthalpy: - Electron gain enthalpy refers to the energy change when an electron is added to a neutral atom in the gas phase. A more negative value indicates a greater tendency to gain an electron. - Elements that are closer to achieving a full outer shell (no...
As we move down the group the atomic size of the molecule increases and the electron affinity also decreases, but sulphur is an exception, as sulphur has a -200 KJ/Mol electron affinity higher than oxygen molecules which are -142KJ/Mol. Due to the smaller size of the sulphur, the outer...
Answer: As we proceed from left to right, the electron gain enthalpy generally becomes more negative. The electron gain enthalpy decreases as one moves along a group. Adding an electron to the smaller 2p-orbital, on the other hand, causes more repulsion than adding an electron to the bigger...
