3. Which of these statements is an accurate description of the ionization energies of elements in the periodic table? F. The ionization energy of lithium is greater than that of potassium.
G. The ionization energy of iodine is greater than that of fluorine.
H. The ionization energy of magnesium is greater than that of sulfur.
J. The ionization energy of krypton is greater than that of neon.

The accurate description of the ionization energies of elements in the periodic table is; the ionization energy of lithium is greater than that of potassium.

In the periodic table, ionization energy decreases down the group and increases across the period. So, as we move from left to right in the table, it takes more energy to remove an electron from the atom.

Lithium and potassium are members of group 1, Lithium is far higher than potassium. It takes more energy to remove an electron from lithium than for potassium.

Hence, the ionization energy of lithium is greater than that of potassium.

option A is correct

Explanation:

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
