The densest chemical element is the metal osmium (Os) - 22,57 g/cm3.
Tungsten has the highest melting point of all metals at 3,422 degrees Celsius.
No. The heaviest naturally-occurring element is uranium (atomic number 92, atomic weight 238.0289). While the substance with the highest density is either element iridium or the element osmium.
Naturally occurring, Uranium. Synthetic, to be determined.
Uranium atoms have 92 protons, which is the highest number found naturally.
Plutonium (atomic number 94) is the last element in the periodic table that may be found naturally, in trace amounts.
At 300 K, osmium (Os) has the highest density among naturally occurring elements.
Which substance has the highest density at room temperature? hydrogen, oxygen, water
Tungsten has the highest melting point of all metals at 3,422 degrees Celsius.
Osmium is the solid element that has the highest density. Opposite of osmium is hydrogen which has the lowest density.
The element with the highest atomic number on the periodic table is uranium. It has an atomic number of 92 and is a naturally occurring element found in small amounts in the Earth's crust.
Iridium is the elemento with the highest density
No. The heaviest naturally-occurring element is uranium (atomic number 92, atomic weight 238.0289). While the substance with the highest density is either element iridium or the element osmium.
If we are talking about elements here, hydrogen is not the heaviest. In fact, hydrogen is the lightest element. There are two ways of answering this question, depending on how you define 'heaviest'. The heaviest element in terms of heaviest per a given number of atoms is the element with the highest atomic weight. This is the element with the largest number of protons, which is presently element 118, ununoctium. When a heavier element is discovered (e.g., element 120), then that will become the new heaviest element. Ununoctium is the heaviest element, but it is man-made. The heaviest naturally-occurring element is uranium (atomic number 92, atomic weight 238.0289). Another way to look at heaviness is in terms of density, which is mass per unit volume. Either of two elements can be considered the element with the highest density: osmium and iridium. The density of the element depends on many factors, so there isn't a single number for density that would allow us to identify one element or the other as the most dense. Each of these elements weigh approximately twice as much as lead. The calculated density of osmium is 22.61 g/cm3 and the calculated density of iridium is 22.65 g/cm3, though the density of iridium has not been experimentally measured to exceed that of osmium.
Naturally occurring, Uranium. Synthetic, to be determined.
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.
Osmium is the most dense naturally occurring substance on Earth. It is about twice as dense as lead. . See the related link below for Osmium. . Although technically not a solid, theoretically the densest material in the universe is matter found at the center of a black hole.
im pretty sure its uranium this for ur homework :D lol i have the same question on mine should be uranium though (u)
