Plasma. It makes up more than 99% of visible matter in the universe, and most of the invisible matter.
Plasma, commonly known as the fourth state of matter, is not abundant on Earth but is prevalent in deep space.
Gas is the state of matter with the most space between molecules. The 4th and most abundant state of matter 'Plasma' can be similarly diffuse, mainly as the electrons and protons in space not bound into molecular gas.
The most abundant mineral in the extracellular space is sodium (Na+)
The phases are solid, liquid, and gas. Plasma is a fourth state of matter relatively rare on earth, but is the most abundant phase of matter in the universe.
The most abundant elemental form of sodium appears as a solid.
Carbon.
Very probable this space is empty, is vacuum.
The most common type of star is the red dwarf.
Tennessee, because of the TVA
carbon
In the gas state of matter the molecules are moving too fast to stick to other molecules. Because they are free floating the molecules expand to fill all of the space available.
Those things, yes, but mostly ice. After elemental hydrogen and helium, water is the most abundant stuff in space. (Not counting "dark matter")
