(a) MgO (b) SrO (c) KF (d) CsF (e) MgF2arrow_forwardFor which of the following substances is the least energy required to convert one mole of the solid into separate ions? (a) MgO (b) SrO (c) KF (d) CsF (e) MgF2arrow_forwardConsider the following energy changes: E(kJ/mol) Mg(g) Mg+(g) + e 735 Mg+ (g) Mg2+(g) + e 1445 O(g) + e + O (g) 141 O(g) + e O2 (g) 878 Magnesium oxide exists as Mg2+O2 and not as Mg+O.

- Think of forming an ionic compound as three steps (this is a simplification, as with all models): (I) removing an electron from the metal; (2) adding an electron to the nonmetal; and (3) allowing the metal cation and nonmetal anion to come together. a. What is the sign of the energy change for each of these three processes? b. In general, what is the sign of the sum of the first two processes? Use examples to support your answer. c. What must be the sign of the sum of the three process d. Given your answer to part c, why do ionic bonds occur? e. Given your above explanations, why is NaCl stable but not Na2Cl? NaCl2? What about MgO compared to MgO2? Mg2O?arrow_forwardGive the periodic group number and number of valence electrons for each of the following atoms. (a) C (b) Cl (c) Ne (d) Si (e) Se (f) Alarrow_forwardWhen an element forms an anion, what happens to the radius? When an element forms a cation, what happens to the radius? Why? Define the term isoelectronic. When comparing size of ions. Which ion has the largest radius and which ion has the smallest radius in an isoelectronic series? Why?arrow_forward
- From their positions in the periodic table, arrange the atoms in each of the following series in order of increasing electronegativity: (a) As, H, N, P, Sb (b) Cl, H, P, S, Si (c) Br, Cl, Ge, H, Sr (d) Ca, H, K, N, Si (e) Cl, Cs, Ge, H, Srarrow_forwardWrite the electron configuration for the monatomic ions formed from the following elements (which form the greatest concentration of monatomic ions in seawater): (a) Cl (b) Na (c) Mg (d) Ca (e) K (f) Br (g) Sr (h) Farrow_forwardIn ionic bonding, the electrons are shared between the atoms. the process of fanning an ionic bond is highly endothermic overall. the bonding that occurs is usually between two nonmetal atoms. a noble gas configuration is fanned far each element or ion. At least two of the above statements are correct.arrow_forward
