The radius trend and the ionization energy trend are exact opposites. Does this make sense? Define electron affinity. Electron affinity values are both exothermic (negative) and endothermic (positive). However, ionization energy values are always endothermic (positive). Explain.
Answer to relevant QuestionsArrange the following groups of atoms in order of in-creasing size. a. Te, S, Se d. Rb, Na, Be b. K, Br, Ni e. Sr, Se, Ne c. Ba, Si, F f. Fe, P, O Rank the elements Be, B, C, N, and O in order of increasing first ionization energy. Explain your reasoning. Use data in this chapter to determine the following. a. The electron affinity of Mg2+ b. The electron affinity of Al+ c. The ionization energy of Cl- d. The ionization energy of Cl e. The electron affinity of Cl+ Diagonal relationships in the periodic table exist as well as vertical relationships. For example, Be and Al are similar in some of their properties, as are B and Si. Rationalize why these diagonal relationships hold for ...Distinguish between the terms electronegativity and electron affinity, covalent bond and ionic bond, and pure covalent bond and polar covalent bond. Characterize the types of bonds in terms of electronegativity difference. ...
