Many elements were not discovered before the 17th century because the technology and scientific methods necessary for their discovery were not yet developed. Additionally, the concept of elements as fundamental building blocks of matter was not fully understood until the advent of modern chemistry in the 18th century.
Many of the first discovered elements were named by their discoverer or the location where they were discovered, such as hydrogen, named by Antoine Lavoisier, and uranium, named after the planet Uranus.
It is unlikely that new elements will be discovered because the periodic table is already well-established and comprehensive. Any new elements would likely be highly unstable and exist only momentarily before decaying into lighter elements.
The periodic table organized elements based on their properties, allowing scientists to identify gaps in the table where new elements might exist. By examining the patterns in elemental properties, such as atomic number and electron configuration, scientists could predict the properties of undiscovered elements and guide their search for these elements. This helped in anticipating the existence and properties of elements before they were officially discovered.
Some elements discovered in the last 100 years include Americium, Curium, Californium, Berkelium, and Moscovium. These elements have been synthesized in laboratories through nuclear reactions and have various applications in nuclear technology and research.
Approx. 25 chemical elements were known in 1800.
Helium, neon, argon, krypton, and xenon were all discovered after 1800. These noble gases were first isolated from air and had distinct properties that led to their identification as new elements.

The first elements to be discovered were those that occur naturally in the environment, such as gold, copper, iron, and sulfur. These elements were known to ancient civilizations long before the concept of elements was formally developed.
