Vor 5 Tagen · Einsteinium is a synthetic chemical element; it has symbol Es and atomic number 99. It is a member of the actinide series and it is the seventh transuranium element. It was named in honor of Albert Einstein . Einsteinium was discovered as a component of the debris of the first hydrogen bomb explosion in 1952.
Vor 2 Tagen · Americium is a synthetic chemical element; it has symbol Am and atomic number 95. It is radioactive and a transuranic member of the actinide series in the periodic table, located under the lanthanide element europium and was thus named after the Americas by analogy.
Vor 3 Tagen · A radioactive actinide metal, neptunium is the first transuranic element. It is named after Neptune, the planet beyond Uranus in the Solar System, which uranium is named after. A neptunium atom has 93 protons and 93 electrons, of which seven are valence electrons. Neptunium metal is silvery and tarnishes when exposed to air.
2. Mai 2024 · moscovium (Mc), artificially produced transuranium element of atomic number 115. In 2010 scientists at the Joint Institute for Nuclear Research in Dubna, Russia, and at the Lawrence Berkeley National Laboratory in Berkeley, California, U.S., announced the production of four atoms of moscovium when calcium -48 was fused with americium -243.
2. Mai 2024 · Er war an der Entdeckung der Elemente Plutonium, Americium, Curium, Berkelium, Californium, Einsteinium, Fermium, Mendelevium, Nobelium und des nach ihm benannten Seaborgium beteiligt. Für seine Arbeiten zur Isolierung und Identifizierung von Transuranen wurde er 1951 mit dem Nobelpreis für Chemie ausgezeichnet. Persönliches.
23. Apr. 2024 · Transition metal, any of various chemical elements that have valence electrons—i.e., electrons that can participate in the formation of chemical bonds—in two shells instead of only one. They occupy the middle portions of the long periods of the periodic table of the elements.
Vor 6 Tagen · TRANSMUTATION IS THE PROCESS WHEN ONE ELEMENT CHANGES TO ANOTHER ELEMENT. There are four types of nuclear reactions: 1. Radioactive decay. 2. Fission. 3. Fusion. 4. Artificial Transmutation (also called "Induced Transmutation")
