Question

1pt metallic character tends to increase as you move in which direction on the period table?

○ a. up a column on the periodic table

○ b. down a column on the periodic table

○ c. from left to right across the periodic table

○ d. from the bottom - left to the top - right of the periodic table

Explanation:

Metallic character refers to the tendency of an element to lose electrons. As we move down a group (column) in the periodic table, the atomic radius increases. This increase in atomic radius means that the outermost electrons are farther from the nucleus and are less strongly attracted to it. As a result, it becomes easier for the element to lose electrons, increasing its metallic character.
When moving up a column, the opposite occurs - the atomic radius decreases, and the metallic character decreases. When moving from left to right across a period, the atomic radius decreases (due to increasing nuclear charge), and elements tend to gain electrons (non - metallic character increases). The direction from the bottom - left to the top - right combines the trends of decreasing metallic character as we move up a column and decreasing metallic character as we move from left to right across a period.

Answer:

B. down a column on the periodic table
