Ionization energies periodic trends

Periodic trends—Ionization energies increase going from left to right across a period. This is because of the increase in nuclear charge. As the nuclear charge increases, the attraction between the electrons and the nucleus increases. This makes it more difficult to remove an electron from the atom. 

Figure 6.21 I The graph shows the first ionization energy (in kj/mol) vs. atomic number for the first 38 elements in the periodic table. The inset in the upper right emphasizes the general periodic trend Ionization energy increases from left to right and bottom to top in the periodic table.

Although the Periodic Trends Ionization Energy movie (eChapter 7.4) depicts clear trends in the magnitudes of first ionization energies, the movie shows that the trend from left to right across the periodic table is not smooth. 

Nonmetals follow the general trends of atomic radii, ionization energy, and electron affinity. Radii increase to the left in any row and down any column on the periodic table. Ionization energies and electron affinities increase up any column and towards the right in any row on the periodic table. The noble gases do not have electron affinity values. Ionization energies are not very important for the nonmetals because they normally form anions. Variations appear whenever the nonmetal has a half-filled or filled subshell of electrons. The electronegativity... 

Identify periodic trends in radii, ionization energy, and electronegativity. 

From Exercise 21-4 we see that the decreasing ionization energies observed for the alkaline earth atoms are readily explained in terms of their increasing size moving down in the periodic table. Notice that the ionization energy trend going down in the periodic table is the same as the trend going to the left in the periodic table.

The usefulness of the main-group elements in materials is related to their properties, which can be predicted from periodic trends. For example, an s-block element has a low ionization energy, which means that its outermost electrons can easily be lost. An s-block element is therefore likely to be a reactive metal with all the characteristics that the name metal implies (Table 1.4, Fig. 1.60). Because ionization energies are... 

Account for periodic trends in atomic radii, ionization energies, and electron affinities (Examples 1.11 and 1.12). 

The first ionization energies of transition metals show gradual upward trends across each row of the periodic table. 

What periodic trends exist for ionization energy ... 

Likewise, from left to right across a period, the forces of attraction between the outermost electron and the nucleus increase. Therefore the ionization energies increase while the atomic radii decrease. Refer to Figure 5-2 for the exceptions to the general trends for ionization energy. 

II. The general trend is for ionization energy to increase as one moves from left to right across the periodic table and to decrease as one moves down this is the inverse of the trend one finds in examining the atomic radius.
