The electron affinity (EA) of an atom _____. is the energy change associated with removing an electron from an atom in the gas phase to form a cation is the energy change associated with adding an additional electron to an atom in the gas phase to form an anion is always a negative number because it is the energy associated with an exothermic process increases as you go from left to right across a period

The electron affinity is the energy released when an electron is added to a neutral atom to make a 1- anion. The table below shows the electron affinities for the 2nd period (row) elements. The value reported is the amount of energy released when an electron is added to a neutral atom. If no energy is released the anion is not stable and that is reported. Explain the overall trend of electron affinity increasing as you move left to right...

Ionization energy (Ei) is the amount of energy required to remove an electron from a neutral...
Ionization energy (Ei) is the amount of energy required to remove an electron from a neutral gaseous atom or gaseous ion. Electrons are attracted to the positively charged nucleus; therefore removing an electron requires energy. The process is endothermic, and so ionization energies have a positive value. The first ionization energy (Ei1) is the energy associated with the removal of an electron from the neutral gaseous atom. The reaction is represented for the generalized atom X as X→X++e− The amount...

In questions 2-4, you may use radius comparisons as given information. IONIZATION ENERGY. Ionization energy refers to energy required to remove an outer electron from an isolated atom. The energy tends to be less for elements with weaker attractions to the nucleus or higher initial energy levels. The general trend is for lower energy for elements lower in columns and higher energy from left to right across rows of the periodic table. There are some notable exceptions. Explain why: 2....

Ionization energy Ionization Energy is the energy required to remove an electron from an atom or ion in the gaseous state. The ionization energy is always positive because it takes energy to remove and electron. 1) Using the figure on the left, which elements have the highest first ionization energies? 2) Does this make sense as to why they have high Ionization energy? ell tentation energi 3) Which elements have the lowest first ionization energies? 4 Does this make sense...

The electron affinities (as delta H values) of chlorine, bromine, and iodine (as gaseous atoms) are -349, -324, and -295 kJ/mol. Based on the electron affinity trend, what would you expect the electron affinity of fluorine (gaseous atom) to be? The electron affinity of fluorine is actually -328 kJ/mol. Suggest an explanation for the difference predicted and actual.

Periodic Trends in Relative Electron Affinity Part B Electron affinity, EA, is the energy required to add an electron to a neutral gaseous atom and is related to an element's position on the periodic table. Electron affinities can be positive, negative, or zero, as shown in the table. Electron affinity Element (kJ/mol) N (nitrogen) >0 Br (bromine) -325 Sr (strontium) -5 Rank the following elements by electron affinity, from most positive to most negative EA value. Rank from most positive...
