A 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. Simulating how up to 20, potassium atoms behave under extreme conditions revealed that the structures formed represent the new, stable state of matter.
Applying pressure to the atoms leads to the formation of two interlinked solid lattice structures, the team says. Chemical 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.
Potassium is one of the simplest metals we know, yet if you squeeze it, it forms very complicated structures. An element is a chemical substance that is made up of a particular kind of atom and hence cannot be broken down or transformed by a chemical reaction into a different element. All atoms of an element have the same number of protons, though they may have different numbers of neutrons and electrons.
A pure chemical compound is a chemical substance that is composed of a particular set of molecules or ions that are chemically bonded. Two or more elements combined into one substance through a chemical reaction, such as water, form a chemical compound. All compounds are substances, but not all substances are compounds. A chemical compound can be either atoms bonded together in molecules or crystals in which atoms, molecules or ions form a crystalline lattice. Compounds made primarily of carbon and hydrogen atoms are called organic compounds, and all others are called inorganic compounds.
Compounds containing bonds between carbon and a metal are called organometallic compounds. A common example of a chemical substance is pure water; it always has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory.
Other chemical substances commonly encountered in pure form are diamond carbon , gold, table salt sodium chloride , and refined sugar sucrose. Simple or seemingly pure substances found in nature can in fact be mixtures of chemical substances. For example, tap water may contain small amounts of dissolved sodium chloride and compounds containing iron, calcium, and many other chemical substances.
Pure distilled water is a substance, but seawater, since it contains ions and complex molecules, is a mixture. A mixture is a material system made up of two or more different substances, which are mixed but not combined chemically. A mixture refers to the physical combination of two or more substances in which the identities of the individual substances are retained.
Mixtures take the form of alloys, solutions, suspensions, and colloids. Naturally occurring sulfur crystals : Sulfur occurs naturally as elemental sulfur, sulfide, and sulfate minerals and in hydrogen sulfide.
This mineral deposit is composed of a mixture of substances. A heterogeneous mixture is a mixture of two or more chemical substances elements or compounds , where the different components can be visually distinguished and easily separated by physical means.
Examples include:. A homogeneous mixture is a mixture of two or more chemical substances elements or compounds , where the different components cannot be visually distinguished. Often separating the components of a homogeneous mixture is more challenging than separating the components of a heterogeneous mixture.
Distinguishing between homogeneous and heterogeneous mixtures is a matter of the scale of sampling. On a small enough scale, any mixture can be said to be heterogeneous, because a sample could be as small as a single molecule. In practical terms, if the property of interest is the same regardless of how much of the mixture is taken, the mixture is homogeneous.
Some mixtures can be separated into their components by physical mechanical or thermal means. Classifying Matter 3 parts : Introduction to classifying matter as a substance or a mixture of substances. Mixtures are described as heterogeneous or homogeneous. Three common methods of separation are described.
An element is a material that consists of a single type of atom, while a compound consists of two or more types of atoms. A chemical element is a pure substance that consists of one type of atom. Each atom has an atomic number, which represents the number of protons that are in the nucleus of a single atom of that element.
The periodic table of elements is ordered by ascending atomic number. The chemical elements are divided into the metals, the metalloids, and the non-metals. Metals, typically found on the left side of the periodic table, are:. In contrast, non-metals, found on the right side of the periodic table to the right of the staircase , are:. Metalloids have some characteristics of metals and some characteristics of non-metals.

Naturally, the electronic properties are highly dependent on the configuration and behavior of the atoms. That's why, e. Their atoms are arranged in different ways and exist in differing numbers of spatial dimensions: 1, 2, 3!
But they are all solids because their atoms remain fixed in place as they do in solids. If you look at your list of different states of matter, only the magnetic states can be considered a description of the electronic properties of a substance rather than of the atoms--the exception that proves the rule!
For after all, electrons themselves can be modeled as existing as one of the states of matter ever heard of Fermi liquid theory or the hydrodynamic theories of conduction? Metals aren't another form of matter, the electrons in them are just funny liquids! Anyway, don't get too caught up in these sorts of classifications. There's no governing body of classifying states of matter.
The dirty little secret of this sort of thing is that we're all just making it up as we go along! Sign up to join this community. The best answers are voted up and rise to the top. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
