how many states of matter are there
Most scientists today would say there are four main, everyday states of matter (solid, liquid, gas, plasma), plus several more exotic ones that appear only in extreme conditions like ultraâcold labs or inside stars and particle colliders.
Quick Scoop: SoâŚhow many are there?
The twist is that there isnât a single âofficialâ number; it depends on how strict you are with the definition of a âstate.â
- Textbook view (classic school answer) : 3
- Solid, liquid, gas.
- Modern everyday-physics view : 4
- Solid, liquid, gas, plasma (the ionized gas that makes up stars, lightning, neon signs).
- Extended physics view (common in popular science) : around 6â7
- Add plasma, BoseâEinstein condensates, and various ultraâcold âcondensateâ phases like fermionic condensates or related exotic forms.
- Ultraânerdy / frontier view : you can list many more exotic phases (quarkâgluon plasma, time crystals, topological phases, etc.), so the count can easily go well beyond 10 if you name them individually.
A good, honest short answer for âhow many states of matter are there?â in 2026 is:
There are four fundamental everyday states (solid, liquid, gas, plasma), and several exotic states like BoseâEinstein condensates and quarkâgluon plasma, so at least 6â7 wellâestablished ones , plus many more specialized phases proposed and studied in modern physics.
Classic vs modern: why the numbers differ
In school, youâre usually told âthree states of matterâ: solid, liquid, and gas. Thatâs still fine for basic life-on-Earth explanations, because that covers ice, water, steam, air, rocks, and so on.
But scientists quickly realized that plasma âgas so hot that electrons are stripped off atoms, turning it into a soup of charged particlesâis not just âhot gas,â it behaves differently enough to count as a separate state. Since stars are mostly plasma, many sources now say four fundamental states : solid, liquid, gas, plasma.
Once you go into quantum and highâenergy physics , things explode into many more âphasesâ of matter, each with unique rules and symmetries.
A quick tour of the main states
Think of the states in layers: everyday, extremeâhot, and extremeâcold.
Everyday states (what most people mean)
- Solid : Particles are packed closely, mostly vibrating in place; matter has a fixed shape and volume (like ice or metal).
- Liquid : Particles are close but can move around each other; fixed volume but no fixed shape (like water).
- Gas : Particles are far apart and move freely; no fixed shape or volume, filling any container (like steam or air).
Highâenergy states
- Plasma (4th state) : Gas heated so much that electrons are stripped from atoms, leaving ions and free electrons.
* Found in stars, lightning, fluorescent lamps, and many fusion experiments.
- Quarkâgluon plasma (often called a 5th state) : Matter so hot and dense that protons and neutrons âmeltâ into their componentsâquarks and gluons.
* Created for tiny moments in highâenergy colliders like the Large Hadron Collider and thought to have filled the early Universe microseconds after the Big Bang.
Ultraâcold quantum states
Cool atoms close to absolute zero and bizarre new behaviors show up.
- BoseâEinstein condensate (BEC) : A cloud of bosonic atoms cooled until they all collapse into the same lowestâenergy quantum state and act like one âsuperâatom.â
* First realized in the lab in 1995 with rubidium atoms.
- Fermionic condensate / related condensates : With fermions (like certain atoms or electrons), you can pair them up so they behave collectively like bosons and condense into a similar ultraâcold quantum state.
Some authors bundle these last two together as âcondensate states,â giving you 7 total : solid, liquid, gas, plasma, quarkâgluon plasma, BoseâEinstein condensate, fermionic condensate.
Exotic and âweirdâ phases: how far can we go?
Beyond those headline states, modern condensedâmatter and highâenergy physics classify a huge variety of exotic or topological phases.
Examples include:
- Topological states of matter (such as the fractional quantum Hall state) with properties defined by deep mathematical structures rather than simple order like âsolidâ vs âliquid.â
- Time crystals , which show a kind of periodic motion in time even in their lowest energy state, breaking timeâtranslation symmetry.
- Various superfluids and superconductors , which allow frictionless flow of liquid or resistanceâfree electric current under special conditions.
Some popular videos or articles will say â22 states of matterâ or throw around big numbers by counting many of these specialized phases separately. Thatâs not wrong as long as you treat them as different phases , but itâs not a fixed, universally agreed list.
What do forums and recent discussions say?
Modern forum and article discussions often go like this:
âSchool says 3, but science YouTube says 7, a TikTok claims 22⌠whatâs real?â
The current expert trend in 2020s popular science is to be transparent:
- Teach 3 or 4 as the basic set for general audiences.
- Acknowledge at least 6â7 wellâstudied states when including quarkâgluon plasma and quantum condensates.
- Emphasize that âstate of matterâ is a concept from physics, and as we discover more complex phases, the list can grow âso itâs better to think in terms of âmany possible phasesâ rather than a single final number.
So if youâre answering a homeworkâstyle question, â3 or 4 â is usually what the teacher expects, depending on whether they count plasma. If youâre in a scienceâforum or deepâdive discussion, saying âat least 6â7, plus many exotic phasesâ is closer to todayâs physics.
