Exercise 1 Which of the following values would you expect for the atomic radius of potassium, atomic number = 19? 97 pm 227 pm
Exercise 2 In a multi-electron atom, the electron that is most easily ionized is the oneclosest to the nucleus. farthest from the nucleus.
Exercise 3 What is the name of the element in Figure 2 that has the highest ionization energy?
Exercise 4 The data coded red in Figures 1 and 2 indicate that the atomic radii decrease as the value of q1 (the atomic number) increases while the ionization energies generally increase as the value of q1 increases. Can you be certain whether the ionization energies are controlled by q1 or r ? yes no
Exercise 5 Which variable, atomic number or atomic radius, appears to be responsible for the difference between the ionization energies of neon and potassium? atomic number atomic radius
Exercise 6 Within a given row of the periodic table, the correlation between atomic radius and electronegativity is direct inverse
