Does Neutronium exist?

Neutronium only dwells under the crushing gravity of a neutron star. Extract a teaspoon of the stuff (roughly equal to the mass of a mountain) and it will decay almost instantly with "tremendous" radioactivity. To consider neutronium a stable element we'd almost need to think of a neutron star as an atomic nucleus.

Is element 120 possible?

Ununennium and unbinilium (elements 119 and 120) are the elements with the lowest atomic numbers that have not yet been synthesized: all the preceding elements have been synthesized, culminating in oganesson (element 118), the heaviest known element, which completes the seventh row of the periodic table.

Is element 140 possible?

However, extended periodic table theories predicted about chemical elements beyond these 118 elements. According to this, Corbomite (Ct) is a chemical element with atomic number 140. However, in real-life science, element 140 has yet to be identified.

Is the periodic table infinite?

While there's no conclusive answer, it seems we still have a lot left to discover. According to nuclear physicist Witold Nazarewicz, there are good reasons to think the periodic table can't be infinite. But that doesn't make predicting its limits any easier.

Is element zero Possible?

The term "neutronium" was coined in 1926 by Andreas von Antropoff for a conjectured form of matter made up of neutrons with no protons or electrons, which he placed as the chemical element of atomic number zero at the head of his new version of the periodic table.

Why Dineutron does not exist?

The experiments have never found dineutrons, it appears that the strong nuclear force is not quite strong enough. Given that the dineutron isn't bound, the diproton is guaranteed not to be bound.

Are there undiscovered stable elements?

Although there are elements we have not yet created or found in nature, scientists already know what they will be and can predict their properties. For example, element 125 has not been observed, but when it is, it will appear in a new row of the periodic table as a transition metal.
