Which element has the highest density?

The first chemical element with the lowest density is Hydrogen and the highest density is Osmium.

What are the top 10 densest elements?

The 10 Densest Metals:

  1. Osmium 22.6 g/cm^3. Similar to Iridium, osmium is a hard-brittle transition metal that looks bluish-white.
  2. Iridium 22.4 g/cm^3. …
  3. Platinum 21.45 g/cm^3. …
  4. Neptunium 20.2 g/cm^3. …
  5. Plutonium 19.84 g/cm^3. …
  6. Tungsten 19.35 g/cm^3. …
  7. Gold 19.32 g/cm^3. …
  8. Uranium 18.95 g/cm^3. …

What are the 3 most dense elements?

The densest gas element is either radon (monatomic), xenon (which forms Xe2 rarely), or possibly Oganesson (element 118). Oganesson may, however, be a liquid at room temperature and pressure. Under ordinary conditions, the least dense element is hydrogen, while the densest element is either osmium or iridium.

Which gas is most dense?

The more dense carbon dioxide gas has filled the container. Natural gas, methane, is less dense than the carbon dioxide, so it floats to the top of the more dense carbon dioxide.

Densities of Common Elements and Compounds
Substance Density grams per mL
Hydrogen gas 0.000089
Helium gas 0.00018
Air 0.00128

Which element is hardest?

The hardest pure element is carbon in the form of a diamond. Diamond is not the hardest substance known to man. Some ceramics are harder, but they consist of multiple elements. Not all forms of carbon are hard.

What is the densest liquid on Earth?

The densest liquid on Earth is the liquid element mercury, which has a density of 13.5 grams per cubic centimeter.

What do you call the element from atomic number 57 70?

Lanthanides are atomic numbers 57–70. Actinides are atomic numbers 89–102.

Which metal is the least dense?

The lightest or least dense metal that is a pure element is lithium, which has a density of 0.534 g/cm3. This makes lithium nearly half as dense as water, so if lithium was not so reactive, a chunk of the metal would float on water. Two other metallic elements are less dense than water.

What is the lightest element on earth?

Hydrogen is the lightest element. Dihydrogen, H2, is a colorless, odorless, tasteless gas.

What is the least dense gas?

Hydrogen, being the lightest existing gas (7% the density of air), seems to be the most appropriate gas for lifting.

Is oxygen less dense than air?

Oxygen is denser than both air and nitrogen, at all temperatures and pressures, but only slightly. Since they don’t separate from each other, we generally don’t worry which is lighter or heavier. The difference in the density of nitrogen and oxygen gas comes from their molecular weight, which is small (4 g/mol).

What is less dense air?

Hydrogen is much less dense than air and is cheaper than helium.

What’s harder than diamond?

The structure of boron nitride in its wurtzite configuration is stronger than diamonds. Boron nitride can also be used to construct nanotubes, aerogels, and a wide variety of other fascinating applications.

Which element is most powerful?

1 Air/wind. Air control is the most strongest element there is. 2 Fire. Fire is a really strong element and this sounds brutal but you can burn down bad people’s houses and burn people you don’t like.

What is the best Zodiac element?

Sign Element Qualities
Leo Fire Hot & Dry
Virgo Earth Cold & Dry
