Guida verificata passo dopo passo1
Understand that elements with similar chemical properties are typically found in the same group (vertical column) of the periodic table because they have the same number of valence electrons.
Identify the group number of sulfur in the periodic table. Sulfur is in Group 16 (also called the chalcogens).
Look for other elements in Group 16. These include oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and polonium (Po).
Compare the given options to sulfur's group: Oxygen is in Group 16, Phosphorus is in Group 15, Chlorine is in Group 17, and Selenium is in Group 16.
Conclude that selenium, being in the same group as sulfur, has chemical properties most similar to sulfur due to having the same number of valence electrons.
