Question

1. observe: choose ionization energy. ionization energy is shown by color. in which parts of the table do you find atoms with the highest, and the lowest, ionization energies?

top - right of the periodic table lowest ionization energies bottoms left of the periodic table.

1. investigate: select groups. the periodic table is divided into metals and nonmetals. metals are to the left of the metalloids and nonmetals to the right. to the left of the table you will see a list of group names. click on each group name to reveal its properties.

what are the properties of alkali metals?
alkali metals are soft, highly reactive have one valence electron low melting and boiling points and react vigorously with water to form hydrogen gas and alkaline solutions

1. analyze: the metallic character of an element is determined by how readily it loses electrons. elements that lose electrons most easily have the greatest metallic character.

what is the relationship between metallic character and ionization energy?

Explanation:

Metallic character is related to how easily an element loses electrons. Ionization energy is the energy required to remove an electron from an atom. If an element has a high metallic character (loses electrons easily), it has a low ionization energy. Conversely, if an element has a low metallic character (does not lose electrons easily), it has a high ionization energy. So, metallic character and ionization energy are inversely related.

Answer:

Metallic character and ionization energy are inversely related.
