Question: What Is The Oldest Element In The Universe?

What was the first element in the universe?

heliumIt took 380,000 years for electrons to be trapped in orbits around nuclei, forming the first atoms.

These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe..

What is the most expensive element?

franciumThe most expensive natural element is francium. Although francium occurs naturally, it decays so quickly that it cannot be collected for use. Only a few atoms of francium have been produced commercially, so if you wanted to produce 100 grams of francium, you could expect to pay a few billion U.S. dollars for it.

What is the strongest thing in the universe?

These explosions generate beams of high-energy radiation, called gamma-ray bursts (GRBs), which are considered by astronomers to be the most powerful thing in the universe.

What metal is rarer than gold?

platinumIf translated into numbers, platinum—for all of its known deposits—is considerably more rare than gold and is the rarest metal of all.

What is the rarest element in the universe?

AstatineAstatine is the rarest naturally occurring element.

Which is the first element of period?

hydrogenThere are only two elements in the first period: hydrogen and helium. We can explain why there is less elements in the first row in modern theories of atomic structure. This is because in quantum physics, this period fills up the 1s orbital.

Why is Aluminium in period 3?

In the whole of period 3, the outer electrons are in 3-level orbitals. … That increases ionisation energies still more as you go across the period. The fall at aluminium. You might expect the aluminium value to be more than the magnesium value because of the extra proton.

What is the 3rd element?

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

Which is the heaviest element in the world?

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.)

What is Period 3 on the periodic table?

The third period contains eight elements: sodium, magnesium, aluminium, silicon, phosphorus, sulfur, chlorine, and argon. The first two, sodium and magnesium, are members of the s-block of the periodic table, while the others are members of the p-block.

Which element is hardest?

carbonThe 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.

Is there an element 119?

Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. Ununennium and Uue are the temporary systematic IUPAC name and symbol respectively, which are used until the element is discovered, confirmed, and a permanent name is decided upon.

Which element is highest universe?

HydrogenHydrogen is the most abundant element in the Universe; helium is second. However, after this, the rank of abundance does not continue to correspond to the atomic number; oxygen has abundance rank 3, but atomic number 8.
