The electron affinity is the energy released when an electron is added to a neutral atom...
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...

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.

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....

How does the ionization energy of the singly charged anion I− relate to the electron affinity of the neutral atom? A) The ionization energy of I− and the electron affinity of I are not related. B) The ionization energy of I− is half the electron affinity of I because the reaction is more favorable. C) The ionization energy of I− is the same magnitude as the electron affinity of I, but has the opposite sign. D) The ionization energy of...

16 Question (1 point) @ See page 376 Electron affinities are experimentally determined by adding electrons to gas phase atoms or ions and measuring the exothermicity or endothermicity of the reaction. Electron additions that increase electron configuration stability and ion stability should yield greater exothermic values. 3rd attempt Ini See Periodic Table O See Hint If the reason explains why some elements have large exothermic electron affinities, place it the box marked "EA> 0" (EA = electron affinity). If the...

Question 9 Which of these statements is false? An anion is always larger than its parent neutral atom. The first electron affinity is always a large negative value. First ionization energy decreases in going down a column (group). Second ionization energies are always larger than first ionization energies. Atomic size decreases in going from left to right across a row (period).
