------------------------------------------------ Use the periodic table to classify each element as a main-group metal, a transition metal, an inner-transition metal, a metalloid, or a nonmetal.

- Main-group metal
- Transition metal
- Inner-transition metal
- Metalloid
- Nonmetal

Answer :

Final answer:

The periodic table can be used to classify elements into main-group metals, transition metals, inner-transition metals, metalloids, and nonmetals.


Explanation:

The periodic table can be used to classify elements into different categories.

  • Main-group metals are found on the left side of the periodic table and have similar properties, such as high reactivity and the tendency to lose electrons to form positive ions. Examples include sodium (Na) and potassium (K).
  • Transition metals are located in the middle of the periodic table and are known for their variable oxidation states and ability to form colorful compounds. Examples include iron (Fe) and copper (Cu).
  • Inner-transition metals are found at the bottom of the periodic table and are divided into two groups: lanthanides and actinides. These metals are known for their radioactive properties and are used in various applications. Examples include cerium (Ce) and uranium (U).
  • Metalloids are located along the zigzag line on the periodic table and have properties in between metals and nonmetals. Examples include silicon (Si) and arsenic (As).
  • Nonmetals are found on the right side of the periodic table and have properties such as low reactivity and the tendency to gain electrons to form negative ions. Examples include oxygen (O) and nitrogen (N).
