Question: What Is The Least Common Element In The Universe?

What are the 3 most abundant elements in the universe?

The first three most abundant elements in the universe are hydrogen, helium, and oxygen (in that order)..

How rare is gold in the universe?

Gold is rare throughout the Universe because it’s a relatively hefty atom, consisting of 79 protons and 118 neutrons. That makes it hard to produce, even in the incredible heat and pressure of the ‘chemical forges’ of supernovae, the deaths of giant stars responsible for creating most chemical elements.

What element makes up 80 percent of the air?

NitrogenNitrogen comprises the greatest part of the atmosphere, at almost 80 percent by volume. Nitrogen is a colorless, odorless, tasteless gas that reacts very little with other substances. The atmosphere also contains oxygen, at about 20 percent.

What’s harder than diamond?

carbon nanotubesBuckypaper. It is well-known since the late 20th-century that there’s a form of carbon that’s even harder than diamonds: carbon nanotubes. By binding carbon together into a hexagonal shape, it can hold a rigid cylindrical-shaped structure more stably than any other structure known to humankind.

What is the most common element in the universe?

HydrogenHydrogen — with just one proton and one electron (it’s the only element without a neutron) — is the simplest element in the universe, which explains why it’s also the most abundant, Nyman said.

What is the rarest element in the universe?

element astatineBut the rarest element? The radioactive element astatine is so rare that its inclusion in the Periodic Table of the Elements was made at first in theoretical character. Currently there are a total of 31 grams of the material on earth.

What is the 3rd element?

LithiumLithium is the 3rd element of the periodic table of elements.

What makes up 80 percent of air?

Air is composed of a mixture of gases and is not a gas in itself. However, air is mostly nitrogen — almost 80 percent of it. Nearly all the rest of it is oxygen, with about 1 percent being argon.

Is Obsidian stronger than diamond?

Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon’s steel scalpel. It is 3 times sharper than diamond and between 500-1000 times sharper than a razor or a surgeon’s steel blade resulting in easier incisions and fewer microscopic ragged tissue cuts. … Obsidian is found all over the world.

What is the hardest thing in the universe?

The Hardest Known Substance In the Universe Is Something Called “Nuclear Pasta”

What is the hardest thing to find on Earth?

AstatineThat’s pretty much the hardest thing to find anywhere. The NPR says that Astatine is so rare that it’s never even been seen directly because if you managed to actually get enough of it together, it would vaporize itself with its own radioactive heat. In fact, on the entire Earth, there is only one ounce of Astatine.

What element is the heaviest?

uraniumThe heaviest element found in any appreciable amount in nature is uranium, atomic number 92. (The atomic number refers to the number of protons in an atom’s nucleus.)

How old is our universe?

13.8 billion yearsThe universe is 13.8 billion years old—here’s how we know. Popular Science.

What is the rarest thing to ever happen?

The rarest thing to ever happen is that the universe exists exactly as it does at this very moment (and by an information-theoretic argument, consequently had all of its events leading up to this moment happen exactly as they did).

What is hottest thing in the universe?

A CERN experiment at the Large Hadron Collider created the highest recorded temperature ever when it reached 9.9 trillion degrees Fahrenheit. The experiment was meant to make a primordial goop called a quark–gluon plasma behave like a frictionless fluid. That’s more than 366,000 times hotter than the center of the Sun.

What is the most expensive thing in the universe?

An astroid named 16 Psyche, after Cupid’s wife, was found to be made almost entirely of iron and nickel. That means, in current US markets, 16 Psyche is worth somewhere around $10,000 quadrillion (the world’s economy is around $74 trillion).

What is the fastest thing in the universe?

These activities all produce or require heat. Laser beams travel at the speed of light, more than 670 million miles per hour, making them the fastest thing in the universe.

What is the least abundant element in the universe?

AstatineThe least abundant naturally occurring element in the universe is Astatine – Wikipedia .
