Question

analyze and interpret data 1. sep interpret data which elements would you characterize as metallic? explain your reasoning. 2. sep interpret data which elements would you characterize as metalloids? explain your reasoning. 3. sep interpret data which elements would you characterize as nonmetals? explain your reasoning. 4. sep develop models how would you describe the relative positions of these elements on the periodic table?

Explanation:

1. Metals are typically characterized by high electrical and thermal conductivity, malleability, ductility, and a shiny luster. On the periodic - table, they are mostly found on the left - hand side and in the middle.
2. Metalloids have properties intermediate between metals and nonmetals. They are located along the staircase - like line on the periodic table between metals and nonmetals.
3. Nonmetals have low electrical and thermal conductivity, are often brittle, and do not have a shiny luster. They are located on the right - hand side of the periodic table.
4. Metals are on the left and middle, metalloids form a diagonal staircase between metals and nonmetals, and nonmetals are on the right of the periodic table.

Answer:

1. Elements on the left - hand side and in the middle of the periodic table (such as sodium, iron, copper) are metallic. Reason: They exhibit properties like high electrical conductivity, malleability, and ductility.
2. Elements along the staircase - like line on the periodic table (such as boron, silicon, germanium) are metalloids. Reason: They have properties intermediate between metals and nonmetals, like semi - conductivity.
3. Elements on the right - hand side of the periodic table (such as oxygen, nitrogen, chlorine) are nonmetals. Reason: They have low electrical conductivity and are often brittle.
4. Metals are predominantly on the left and in the middle of the periodic table. Metalloids form a diagonal "staircase" separating metals from nonmetals. Nonmetals are located on the right - hand side of the periodic table.
