Predict which element in each of the following pairs has the larger ionization energy K or...
Problem 9. (6 points) Predict which element in each of the following pairs is more electronegative according to the general trends in the periodic table. (a) Se or Br (b)C or B (c) Te or S (d)Ba or Be
Which has the larger ionization energy? Sodium (Na), or potassium (K). Why? Which has the larger radius? Sulfur (S), or the sulfide anion (S2-). Why? If an element has a "large negative" electron affinity number where would it be located on the periodic table?
explanation needed thank u
