One of the most fundamental concepts in chemistry is the structure of atoms. Atoms are made up of three subatomic particles: protons, neutrons, and electrons. The number of protons in an atom determines what element it is, while the number of electrons determines its chemical properties. In this article, we will explore which element has 18 electrons.
The element with 18 electrons is argon. Argon is a noble gas and is the third member of the group 18 elements in the periodic table. It is a colorless, odorless, and tasteless gas that makes up about 0.934% of the Earth's atmosphere.
Argon was discovered in 1894 by Sir William Ramsay and Lord Rayleigh. They were studying the properties of air and noticed that a certain fraction of it did not react with other elements. They isolated this fraction and discovered it was a new element, which they named argon, after the Greek word for lazy or inactive.
Argon has several important applications in industry. It is used in light bulbs to help prevent the filament from burning out too quickly. It is also used in welding, as a shielding gas to protect the weld from oxygen and other gases in the air. Additionally, argon is used in the production of semiconductors and other electronics.
In addition to its industrial applications, argon has several medical uses. It is used in lasers for eye surgery and in gas chromatography to analyze blood and urine samples.
In conclusion, the element with 18 electrons is argon. As a noble gas, it has several important applications in industry and medicine. Its discovery has also contributed to our understanding of the nature of air and the composition of the Earth's atmosphere.
