What else can I help you with?
Are most elements man made or natural?
All the existing elements are natural the man made elements are rare and have a very short life.
How many elements shown in the periodic table do not occur in nature on earth?
118 total - 92 natural elements= 26 elements that do not naturally occur===========================
What is the heavist element in the periodic table?
The heaviest stable element is bismuth, atomic number 83, atomic weight 208.9804). Any heavier element is radioactive, which means it decays into lighter elements - uranium, the heaviest naturally occurring element, will eventually decay into lead-207.
How are isotopes and ions and elements produced?
You add or remove one or more neutrons from each atom.
What is Einsteinium's natural state?
Einsteinium is a radioactive synthetic element that is not found naturally on Earth. It is typically produced in nuclear reactions involving uranium and transuranium elements.
What natural provides enough energy for the nuclear fusion reactions that create the heaviest element?
The violent creation of the solar system. There where much heavy elements on this planet before are civilization started its climb. These elements that we have now will deplete further and will not leave much left for the next civilization. It is a act of constant depletion.
Is uranium haviest natutural element?
Yes, uranium has the heaviest atomic mass between natural elements (238,02891).
What is the heaviest type of element?
The heaviest natural element is Uranium (number 92). There are made heavier elements (I think the heaviest is ununheksium, number 116), but these atoms only live in less than a second before they split into smaller atoms.
How many natural elements are there?
Out of the first 92 elements, 1 being hydrogen (H) and 92 being uranium (U), there are 90 that are naturally occurring. Technetium (Tc) and promethium (Pm) are man-made elements and do not have any isotopes occurring naturally.
Which is the heaviest radioactive element?
The heaviest natural radioactive element is Uranium.Man made elements are continuously being made. The latest heaviest superheavyweight man made element to be discovered is element 117 (it is still so new that it hasn't been given a name yet).A little different bit of information about Fermium, a team has captured a piece of its spectrum-the wavelengths of light it absorbs-making it the heaviest element ever to be so measured. It was made in the 1952 detonation of the first thermonuclear bomb. It does not make it as the heaviest element, just the heaviest to have it's light spectrum captured.
Are most elements man made or natural?
All the existing elements are natural the man made elements are rare and have a very short life.
Heaviest member of group 2 in the periodic table?
Ununhexium is the heaviest metal in the periodic table of elements. It is man made however, so it might not count. The heaviest natural metal might be Radium.
What actinide element is the heaviest that occurs naturally on earth?
Uranium because uranium has the highest atomic number, 92, of the natural, actinide elements. Elements higher than 92 are man-made elements. Check the periodic tables to see for yourself!~
How many elements shown in the periodic table do not occur in nature on earth?
118 total - 92 natural elements= 26 elements that do not naturally occur===========================
Is iron the heaviest element made in abundance in massive stars?
No, iron is not the heaviest element made in massive stars. Massive stars produce elements through nuclear fusion in their cores, creating heavier elements than iron, such as lead, gold, and uranium. Iron is often referred to as the endpoint of nuclear fusion in massive stars because the energy required to fuse iron exceeds the energy output of the reaction.
What is the heavist element in the periodic table?
The heaviest stable element is bismuth, atomic number 83, atomic weight 208.9804). Any heavier element is radioactive, which means it decays into lighter elements - uranium, the heaviest naturally occurring element, will eventually decay into lead-207.
How are isotopes and ions and elements produced?
