Using a periodic table, fill in each of the following blanks with the most appropriate answer. a) The alkali earth metal with the largest atomic radius is. b) All of the elements in group 7 have valence electrons with the general electron configuration. c) The element in period 4 with the largest ionization energy is. d) An atom of K is (smaller/larger) than an atom of F.
In questions 2-4, you may use radius comparisons as given information. IONIZATION ENERGY. Ionization energy refers to energy required to remove an outer electron from an isolated atom. The energy tends to be less for elements with weaker attractions to the nucleus or higher initial energy levels. The general trend is for lower energy for elements lower in columns and higher energy from left to right across rows of the periodic table. There are some notable exceptions. Explain why: 2....
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?
