I have just had to research this question for materials science homework.The answer that i have come up with is -Hydrogen is the lightest stable element with only one proton.Uranium is the heaviest with 92 protons.
But scientist have discovered an eliment called eliment 118 that fits just below radon on the Periodic Table this eliment was supposed to have been discovered in 1999 but was said to have been made up. So i will go with uranium as being the heaviest known stable element for now.
What else can I help you with?
Which element is the heaviest actininde that occurs naturally on earth?
Uranium is the heaviest naturally occurring actinide.
What is heaviest element on the periodic table of elements?
The heaviest element in the periodic table (known in March 2013) is ununoctium.
What is the heaviest element found on earth?
If you are talking about element sin the periodic table, it is ununoctium(Uuo)
What is the heaviest usable metal?
Bismuth (Bi) is the heaviest nonradioactive element but the next heaviest is Lead (Pb) and that is much more commonly used. The heaviest element that is naturally occurring, and also usable, though radioactive, is Uranium (U).
What is the heaviest element?
What do you mean by "heaviest"? If you have a lot of feathers, it weighs more than a little bit of lead! There are two ways to answer this question. One is what is the element with the highest atomic weight, and what is the element with the highest density. The element with the highest atomic weight is the heaviest for the same number of atoms, and the most dense element is the heaviest element for the same volume of material.Uranium (U) (atomic number 92) is the naturally occurring element with the highest atomic weight. Plutonium might be argued to be the heaviest naturally occurring element, but it many scientists disregard this. A few atoms of plutonium have been detected in naturally occurring uranium, but the trace ammounts were formed by neutron capture where some neutrons released in the natural decay (spontaneous fission) of uranium were captured by some other uranium atoms and transmuted into plutonium.Ununoctium (Uuo) (atomic number 118) is the heaviest synthetic element, although only a couple of atoms have ever been made!The most dense element is osmium (Os), which a density of 22.61 grams per cm3 (which is 22.61 times more dense than water!) That's almost twice the density of lead!See the Related Question below for more information about the most dense elements.Natural, known or possible?Natural 92 Uranium Heaviest element of all those in the earth when it formed (~6 billion years ago) that has not decayed to practically undetectable levels due to a short halflife.Known 112 Copernicium This changes periodically but as of February 24, 2010 element 112 was the heaviest known.Possible ∞ "Infinitium" I see no theoretical reason limiting the heaviest element, only practical.
How many electrons does the heaviest naturally occurring element have?
Uranium, number 92 is the last of the naturally occurring elements and, of course, it has 92 electrons.
Which element is the heaviest actininde that occurs naturally on earth?
Uranium is the heaviest naturally occurring actinide.
Is mercury the heaviest naturally occurring element?
No, the three densest elements under ordinary conditions are osmium, iridium and platinum, in that order. Please see the link. *************************** However, mercury is the densest liquid at room temperature.
What is the heaviest element known to exist naturally on earth in quantities detectable by purely chemical test methods?
Now californium is considered as the heaviest naturally occurring chemical element.
What is heaviest element on the periodic table of elements?
The heaviest element in the periodic table (known in March 2013) is ununoctium.
What solid weighs the most?
Osmium is the densest naturally occurring element and it is often considered the heaviest naturally occurring solid substance. However, man-made substances like depleted uranium can be even denser.
Are there no new elements to be discovered?
No. Uranium is the heaviest naturally occurring element. More elements can be prepared artificially. New isotopes of the element may be discovered.
What is the heviest element?
The heviest element is mercury. It is heavy because it is so dense.
Which is the hevest element in the periodic table?
The heaviest (hevest?) naturally occurring element is Uranium (238 a.m.u.) but the heaviest known element is atom number 114, 117 or 118, the exact mass being unknown but over 250.
The heaviest element found in nature is?
I believe it is Uranium. All elements heavier than uranium are man-made. Here's an interesting article... http://space.newscientist.com/article/dn13828-has-the-heaviest-element-been-found.html
How many chemical elements occur naturaly in the universe?
There are 94 naturally occurring chemical elements in the universe. These elements range from hydrogen, the most abundant, to uranium, the heaviest naturally occurring element.
What is the heaviest element found on earth?
If you are talking about element sin the periodic table, it is ununoctium(Uuo)
