This list includes 9 Chemical Elements that start with S, from “Samarium” to “Sulfur”. They span metals, metalloids, and nonmetals, each used in everyday and industrial applications. See the A–Z index at /elements-a-to-z to explore other letters.
Chemical elements that start with S are the subset of elements whose English names begin with the letter S. Notably, sulfur appears in historical records and shaped early medicine, agriculture, and industry.
Below you’ll find the table with Atomic number, Element, Atomic weight, and Discovery year.
Atomic number: Shows the number of protons in the nucleus and helps you order elements by increasing atomic number.
Element: The element name appears here so you can quickly recognize familiar elements and compare names.
Atomic weight: Gives the standard atomic weight (three decimals) so you can compare relative masses.
Discovery year: Lists when the element was discovered or first recorded, helping you see historical context.

Descriptions
Scandium
A light, silvery transition metal found in rare minerals; used in aerospace alloys and high-intensity lamps; naturally occurring.
Samarium
A rare-earth metal used in permanent magnets and nuclear control rods; found in minerals like monazite; naturally occurring.
Seaborgium
A synthetic, radioactive transactinide created in particle accelerators; no commercial uses, studied for nuclear physics only.
Selenium
A nonmetal used in glassmaking, electronics, and as a trace nutrient; occurs in ores and as a byproduct of metal refining; naturally occurring.
Silicon
A metalloid abundant in Earth’s crust, essential for semiconductors, glass, and ceramics; naturally occurring (silicates).
Silver
A lustrous precious metal long used for coins, jewelry, and high-conductivity electronics; naturally occurring in ores.
Sodium
A highly reactive alkali metal vital in salts, industry, and biology; produced commercially and found in minerals like halite; naturally occurring.
Strontium
An alkaline-earth metal used in fireworks and ferrite magnets, found in the mineral celestine; naturally occurring.
Sulfur
A yellow nonmetal used in fertilizers, sulfuric acid, and vulcanization; widely found in minerals and volcanic emissions; naturally occurring.
