Answer :
Final answer:
The periodic table can be used to classify elements as main-group metals, transition metals, inner-transition metals, metalloids, or nonmetals.
Explanation:
Classification of Elements
The periodic table can be used to classify elements as follows:
- Main-group metal: These are elements found in the s-block and p-block of the periodic table. They are typically shiny, malleable, and good conductors of heat and electricity. Examples include sodium (Na) and oxygen (O).
- Transition metal: These elements are found in the d-block of the periodic table. They have high melting and boiling points and exhibit variable oxidation states. Examples include iron (Fe) and copper (Cu).
- Inner-transition metal: These elements are found in the f-block of the periodic table. They are typically radioactive and have unique properties. Examples include uranium (U) and plutonium (Pu).
- Metalloid: These elements are found along the border between metals and nonmetals on the periodic table. They have properties intermediate between metals and nonmetals. Examples include silicon (Si) and arsenic (As).
- Nonmetal: These elements are found on the right side of the periodic table. They are typically poor conductors of heat and electricity. Examples include hydrogen (H) and nitrogen (N).
