Complete answer: Electron affinity is characterized as the energy shift (in kJ/mol) of the gaseo?
) Trends: As with ionization energy, there are two rules that govern the periodic trends of electron affinities: Electron affinity becomes less negative down a group. Study with Quizlet and memorize flashcards containing terms like Which best describes the trends in electronegativity on the periodic table?, Which element has a larger atomic radius than sulfur?, Which element has the smallest atomic radius? and more Which correctly summarizes the trend in electron affinity? B - It tends to be more. Which correctly summarizes the trend in electron affinity? It tends to be more negative across a period. List their electron affinity below in kJ/mol Graph the electron affinities from above in kJ/mol on the Y axis against the atomic numbers on the X axis. city of toronto power outage Electron Affinity Trend: _____ as you go across a period; the stronger the attraction, the more energy is released. Based on this trend, an electron will be most strongly attracted to, Which correctly summarizes the trend in electron affinity?, Which ion was formed by providing the second ionization energy to remove an electron? and more. Electron affinity increases down the periodic table. For this discussion, we will use the definition of EA that is consistent with it being a zeroth ionization energy: a more positive (larger) value means that the EA is higher (meaning stronger affinity toward an electron) Across a period: Similar to ionization energy, EA generally increases across a row of the periodic table; this observation is consistent with. And, more negative value of electron affinity means atom will have difficulty in gaining an electron. tactical assassin 2 unblocked games The trend in electron affinity across a period and down a group is influenced by atomic structure, particularly the number of protons in the nucleus and the distance of the valence electrons from the. Which correctly summarizes the trend in electron affinity? It tends to be more negative across a period. For instance the electron affinity for benzene is negative, as is that of naphthalene, while those of anthracene, phenanthrene and pyrene are positive.
