Potassium is one of the simplest metals we know, yet if you squeeze it, it forms very complicated structures. The work was carried out in collaboration with scientists from Xi’an Jiantong University in China. The study, published in the journal Proceedings of the National Academy of Sciences, was supported by the European Research Council and the Engineering and Physical Sciences Research Council. Simulating how up to 20,000 potassium atoms behave under extreme conditions revealed that the structures formed represent the new, stable state of matter.Īpplying pressure to the atoms leads to the formation of two interlinked solid lattice structures, the team says.Ĭhemical interactions between atoms in one lattice are strong, meaning they stay in a solid form when the structure is heated, while the other atoms melt into a liquid state.

High performance computingĪ team led by scientists from the University of Edinburgh used powerful computer simulations to study the existence of the state – known as the chain-melted state. Until now, it was unclear if the unusual structures represented a distinct state of matter, or existed as transition stages between two distinct states. Under the right conditions, over half a dozen elements – including sodium and bismuth – are thought to be capable of existing in the newly discovered state, researchers say. However, the structure also contains a second set of potassium atoms that are in a fluid arrangement. Novel structureĪpplying high pressures and temperatures to potassium – a simple metal – creates a state in which most of the element’s atoms form a solid lattice structure, the findings show. Researchers have found, however, that some elements can, when subjected to extreme conditions, take on the properties of both solid and liquid states. Until now, the atoms in physical material were understood to exist typically in one of three states – solid, liquid or gas. For many of the larger elements in the periodic table we can only hypothesise their state using patterns in the groups they exist in as not enough atoms have been created that last long enough for the synthetic elements to be studied.Scientists have discovered a new state of physical matter in which atoms can exist as both solid and liquid simultaneously.

In the case of many of these atoms also not enough atoms have been created to witness their state of matter. This is often because due to the radioactivity of these elements they decay very quickly breaking down into smaller elements and releasing alpha, beta and gamma radiation.

In the periodic table there are a number of elements in the actinide and lanthanide series that have unknown states. They also have very low boiling and melting points requiring very very low temperature to turn them into liquids.

Gas particles often are poor conductors of heat and electricity due to the wide spaces between the atoms.

Gaseous particles can flow due to their free movement and can also be squashed by reducing the volume of the container it is in. Like liquids gases will often take the shape of the container they are placed in and will exhibit pressure on the surfaces of such a container. In a similar way they are free to move and less densely packed but the atoms are spread over much greater distances. Gaseous atoms are much more spread out than liquids. With a few exceptions such as the alkali metals which will readily float on water. Liquids are often less dense than solids as they are less closely packed with space between the molecules. Liquids also often have lower boiling points than solids as less energy is needed to overcome the forces between the particles meaning liquids will readily turn into gases. The particles in a liquid often move around each other freely, because of this liquids often take the shape of their container and can be poured as the weak attractions between the atoms mean they can flow. Due to the atoms in a solid being held in a fixed position, solids often have a defined volume and shape/structure. Property wise many solids like metal are good electrical conductors due to the closely packed atoms and also good conductors of heat as vibrations can easily travel through them. However some solids may be brittle and weak depending on their bonding. Solids are very strong usually and will resist pressure and forces applied to them.

Regular is usually defined as being in a lattice like structure where atoms are the same size and in layers. Solids are tightly packed with their atoms having a regular arrangement.
