Here are the essential concepts you must grasp in order to answer the question correctly.
Periodic Table Organization
The periodic table is organized into periods (rows) and groups (columns) that categorize elements based on their atomic structure and properties. Elements in the same group often exhibit similar chemical behaviors, while those in the same period have the same number of electron shells. Understanding this organization is crucial for identifying the location and classification of elements.

Element Classification
Elements are classified as metals, nonmetals, or semimetals (metalloids) based on their physical and chemical properties. Metals are typically conductive, malleable, and ductile, while nonmetals are usually poor conductors and more brittle. Semimetals exhibit properties of both metals and nonmetals, making their classification essential for understanding their behavior in reactions.

Group 6A Elements
Group 6A of the periodic table, also known as the chalcogens, includes elements like oxygen, sulfur, and selenium. These elements typically have six valence electrons and can form various compounds, often exhibiting nonmetallic characteristics. Identifying the specific element in period 4, group 6A is key to determining its classification and properties.
