- Americium.
- Curium.
- Berkelium.
- Californium.
- Einsteinium.
- Fermium.
- Mendelevium.
- Nobelium.
When did Albert Ghiorso discover elements?
In 1953, in a collaboration with Argonne Lab, Ghiorso and collaborators sought and found elements 99 (einsteinium) and 100 (fermium), identified by their characteristic radiation in dust collected by airplanes from the first thermonuclear explosion (the Mike test).
Who discovered the most elements?
Albert Ghiorso
Albert Ghiorso (1915-2010) was an American nuclear scientist who co-discovered a world-record twelve elements on the periodic table.
Who discovered the first element?
Hennig Brand
Although elements such as gold, silver, tin, copper, lead and mercury have been known since antiquity, the first scientific discovery of an element occurred in 1649 when Hennig Brand discovered phosphorous.
What did Mendeleev name gallium before it was named gallium?
eka-aluminum
The existence of gallium had been predicted in 1871 by Dmitri Mendeleev, the Russian chemist who published the first periodic table of the elements. Mendeleev noted a gap in his table and named the missing element “eka-aluminum” because he determined that its location was one place away from aluminum in the table.
Who modernized the periodic table?
Hubbard (1870-1943) was a member of the U.S. Bureau of Standards in the 1920s. He modernized Mendeleev’s periodic table and in 1924 he produced a Periodic Table of Elements (called the Periodic Chart of the Atoms) which was distributed to schools and universities.
Who discovered oxygen?

Color of the elements
| Hydrogen | Colorless | Thallium |
|---|---|---|
| Bromine | Red | Moscovium |
| Krypton | Colorless | Livermorium |
| Rubidium | Silver | Tennessine |
| Strontium | Silver | Oganesson |
What do we now call eka-Aluminium?
Dmitri Mendeleev predicted the existence of Gallium — which he referred to as “eka-aluminium” — a few years before it was first discovered, and even correctly predicted several of its properties, all based on its position in his new discovery, the Periodic Table of the Elements.
What are the 7 unknown elements?
Mendeleev’s Predicted Elements
- Eka-boron (scandium)
- Eka-aluminium (gallium)
- Eka-manganese (technetium)
- Eka-silicon (germanium)
Who is the father of periodic?

Periodic table/Inventors
Internet search giant Google has dedicated a Doodle to Russian chemist Dmitri Mendeleev on his 182nd birth anniversary. Born on February 8, 1834, Mendeleev is popularly known as the “Father of Periodic Table”.
