Question

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. a. metals tend to have low ionization energies. what properties of elements in the metal groups do you think are the result of this tendency? b. except for the noble gases, nonmetals tend to have high electron affinities. what properties of nonmetals do you think are the result of this tendency? 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. a. which group has the greatest metallic character? b. which group has the lowest metallic character? c. what is the relationship between metallic character and ionization energy?

Explanation:

A. Since metals have low ionization energies, they tend to lose electrons easily. This leads to properties like high electrical and thermal conductivity (due to free - moving electrons), malleability and ductility (ability to be shaped as electrons can move freely between atoms).
B. Non - metals with high electron affinities tend to gain electrons. This results in properties like being poor conductors of heat and electricity (as they don't have free - moving electrons easily), and often forming negative ions in chemical reactions.
For the analysis part:
A. Group 1 (alkali metals) has the greatest metallic character as they have only one valence electron and can lose it very easily.
B. Group 18 (noble gases) has the lowest metallic character as they have a full valence shell and are very stable, not easily losing electrons.
C. There is an inverse relationship between metallic character and ionization energy. As ionization energy increases, it becomes more difficult for an element to lose electrons, so the metallic character decreases.

Answer:

A. Properties like high electrical and thermal conductivity, malleability, ductility.
B. Properties like being poor conductors, forming negative ions.
A. Group 1 (alkali metals)
B. Group 18 (noble gases)
C. Inverse relationship.
