Fermium is an unstable actinide metal that is synthetically produced in laboratory environments. All atoms have 100 protons in their nuclei, but they can vary in the number of neurons depending on their isotope.Answer and Explanation: The element fermium was first found in the debris from a ...
What are the Actinide metal structures? How heavy is osmium? Is mercury a heavier element than tin? What is an alkaline earth metal? Copper is an example of what type of metal? What are the rare earth metals on the periodic table?
It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, structure, behaviour, and changes that occur when they interact with other things. The quantum mechanical approach is currently used...
Ammonia is a slightly basic compound, and Nitrogen is a non-metal. And, down the group, basicity increases. As it belongs to the VA group, Nitrogen has 5 electrons in its valence shell and has valency equal to three; and in a few compounds, it may extend to four. Nitrogen uses only...
This version of the periodic table is a little wider than you might be used to, since we're inserting the lanthanide and actinide elements into rows 6 and 7. (These elements are normally shown separately from the main table to avoid making it too wide.)The sixth row of the periodic ...
@valleyfiah- Mercury is one of the most unique elements in the periodic table. The metal is only one of two elements that are liquid at standard temperature and pressure (stp). Mercury also has a very short temperature range between the freezing and boiling points. Mercury is the only trans...
What type of element is zirconium? In other words, what is it classified as on the periodic table? What is the name of the Group 1 elements in the periodic table? An element in the lower-left corner of the periodic table: a. is either a metal or metalloid. b. is either a metalloid...
even though its enrichment has fallen significantly. This Uranium can be used inadvanced fast reactorsas fuel and is a valuable energy source. Theminor actinides, which include Neptunium, Americium, and Curium, are long-lived nuclides that cause serious concern when it comes to storing them for...
What is the atomic number of the element that should theoretically be the noble gas below Rn? What is the valence electron configuration for the element in Period 4, Group 6A? What is the one element in the s block on the periodic table that is not a metal? An element ha...
There is over 100x more U238 in nature than U235, so the time that 200 years of uranium can last humanity turns into 20,000. There are also significantly more free neutrons in fast reactors. Since the probability of fission is lower for faster energies for every actinide, the neutron ...
