In recent times, periodic tablewithatomic mass has become increasingly relevant in various contexts. PeriodicTable of Elements - PubChem. Interactive periodic table with up-to-date element property data collected from authoritative sources. Look up chemical element names, symbols, atomic masses and other properties, visualize trends, or even test your elements knowledge by playing a periodic table game!
In relation to this, explore how atomic mass changes with atomic number in the periodic table of elements via interactive plots. In this context, neptunium | Np (Element) - PubChem. There are 25 known radioactive isotopes of neptunium ranging in atomic weights from 225 to 244 with 5 of those as metastable isotopes. Equally important, the most stable are Np-237 with a half-life of 2.14 million years; Np-236 with a half-life of 154,000 years; and Np-235 with a half-life of 396 days.
Silicon | Si (Element) - PubChem. Because molecules, atoms, and ions of the stable isotopes of silicon possess slightly different physical and chemical properties, they commonly will be fractionated during physical, chemical, and biological processes, giving rise to variations in isotopic abundances and in atomic weights. Periodic Table element Summary Lutetium Lutetium is a chemical element with symbol Lu and atomic number 71. Classified as a lanthanide, Lutetium is a solid at 25°C (room temperature).
Hydrogen | H (Element) - PubChem. Building on this, hydrogen is estimated to make up more than 90% of all the atoms three quarters of the mass of the universe! This element is found in the stars, and plays an important part in powering the universe through both the proton-proton reaction and carbon-nitrogen cycle. Periodic Table element Summary Silver Silver is a chemical element with symbol Ag and atomic number 47. Building on this, classified as a transition metal, Silver is a solid at 25°C (room temperature).
