Which of the following are true for main-group elements ?
Use the general periodic trends you learned in class, not the experimental values from the figures in the text.
For questions that refer to ionization energy, consider only first ionization energies.
(a) Ionization energy tends to decrease from top to bottom in a column of the periodic table.
(b) Electron affinity tends to become more negative from left to right across a row of the periodic table.
(c) The ionization energy of Si is greater than C
(d) The atomic radius of Ba is greater than Te
(e) The atomic radius of Na is less than O
you must enter all true statements in one alphabetical lower case group,
e.g., if a) b) and e) are true you would enter abe
