ANSWER:Solution 76 QPHere, we have to fill the given statement.Step 1 of 2The given elements are 4th period elementsIonization energy :It is the amount of energy required to remove an electron from a gaseous atom or ion.And to form a positive ion.Na Na+ + e-.As you move left to right across the periodic table the ionization energy increases.Atomic size:It is the average distance between a nucleus and outermost electron.As you move left to right across the periodic table the atomic size decreases.Metallic character:Metallic character is an element loses valence electrons easily.As you move left to right across the periodic table the metallic character decreases. ____________________________________________________________________________
