An alternative definition of electronegativity is electronegativity= constant (i. e — e. a.) where i. e. is the ionization energy and e. a. is the electron affinity using the sign conventions of this book. use data in chapter 12 to calculate the (i. e. - e. a.) term for f, cl, br, and i. do these values show the same trend as the electronegativity values given in this chapter? the first ionization energies of the halogens are 1678, 1255, 1138, and 1007 kj/mol, respectively.

For a patient with the following pes statement and interventions, which would be the most appropriate monitoring and evaluating data? pes statement: inadequate calcium intake related to food and nutrition related knowledge deficit as evidenced by statements that the only dietary source of calcium is milk and she believes that she is lactose intolerant. patient’s nutrition prescription is for a diet providing 1200 mg calcium per day. patient was provided with in-depth nutrition education on alternative dietary and supplement sources of calcium. a. calcium intake (at subsequent visit) b. knowledge assessment by asking patient to identify food sources from menus and shopping list (at the end of the current visit) c. serum calcium (at next visit) d. both a and b e. both a and c
