Questions 15 through 16...
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....

Write a chemical equation representing the second ionization energy for lithium. Use e as the symbol for an electron. chemical equation: Li2+ + 1e-
The minimum energy needed to eject an electron from an atom is called its ionization energy I. In atomic physics, I is usually measured in electron-Volts (eV), with 1 eV being the energy needed to move a charge of 1 e across an electrostatic potential difference of 1 V, 1 eV = 1.602 x 10-19 CX1V -1.602 x 10-19 J. For the hydrogen atom | = 13.60 eV. If a photon ejects an electron with kinetic energy 5.0 eV from...
