Answer :
Final answer:
As you move from left to right on the periodic table, you encounter metals, metalloids, nonmetals, and transition metals in that order. Metals are found on the left, followed by metalloids, then nonmetals, with transition metals situated in the center. Each category has distinct properties that define them.
Explanation:
Chemical Properties of Elements on the Periodic Table
When categorizing elements on the periodic table as you move from left to right, the sequence based on their properties is as follows:
- Metals (10): These elements are found on the left side of the periodic table and are characterized by their ability to conduct heat and electricity, malleability, and ductility. Examples include sodium (Na), magnesium (Mg), and aluminum (Al).
- Metalloids (9): Located to the right of the metals, metalloids exhibit properties of both metals and nonmetals. They are useful in semiconductors, such as silicon (Si) and arsenic (As).
- Nonmetals (11): Found further right on the periodic table, nonmetals are poor conductors of heat and electricity and include elements like oxygen (O) and nitrogen (N).
- Transition Metals (8): These elements, which include iron (Fe), copper (Cu), and gold (Au), are found in the center of the periodic table. They have unique properties, including the ability to form variable oxidation states and colored compounds.
The sequence from left to right is thus: metals (10), metalloids (9), nonmetals (11), and transition metals (8).
