Oxygen, selenium, tellurium, and polonium are in the same family as sulfur. They belong to the chalcogen group in the periodic table and share similar chemical properties.
Sulfur is in period 3 of the periodic table.
Nitrogen is in Group 15 (also known as Group 5A) on the periodic table. It is located in the p-block.
An element below phosphorus in the periodic table would be expected to be more reactive. For example, sulfur is below phosphorus in the periodic table and is more reactive.
Sulfur has been known since ancient times and was not "added" to the periodic table. It has always been a recognized element and was formally included in the periodic table in the 19th century by Dmitri Mendeleev.
Sulfur is not a transition metal; it is a non-metal. Transition metals are elements found in the d-block of the periodic table. Sulfur is located in the p-block of the periodic table.
Sulfur
The block of the periodic table that is the largest is the s-block, which includes the alkali metals and alkaline earth metals. These elements are located in groups 1 and 2 on the periodic table.
Silver (Ag) is located in block d of the periodic table of elements.
Oxygen and sulfur belong to block p on the periodic table. Block p elements are characterized by their electron configurations ending in the p orbital.
Sulfur (S, element number 16) is on the third period of the periodic table.
Carbon is found in the p-block of the periodic table.
The transition metals are located in groups 3 - 12 on the Periodic Table.
Oxygen, selenium, tellurium, and polonium are in the same family as sulfur. They belong to the chalcogen group in the periodic table and share similar chemical properties.
Neon is a Noble Gas located in the p-block on the periodic table.
Elements in the periodic table that are similar to sulfur would be oxygen, and selenium
Non-metals are on the right side of the periodic table. Carbon, nitrogen, oxygen, fluorine, sulfur, etc are nonmetals.
