It isn't. Unless you mean why is matter considered mostly empty space, in which case the answer is: because it is. The space considered to be occupied by atoms is mostly the electron cloud, the nucleus only takes up a very small portion of the atom. For example, the nuclear diameter compared to the atomic diameter is 1:23000 for uranium and 1:145000 for hydrogen.
What else can I help you with?
In which state of matter do the particles spread apart and fill all the space available to them?
Very probable this space is empty, is vacuum.
Do atoms have empty space?
Yes. In 1908, Rutherford conducted an experiment of shooting a beam of alpha particles through a sheet of tinfoil. Most of the alpha particles went straight through the foil, which proves that there are empty spaces in atoms. And the rest of the particles that didn't go straight through the foil are deflected at acute angles, those particles are deflected by the positive nucleus in the center of the atoms.
Most of the matter in the universe exists as?
Matter is made up of elements and compounds, which are made up of atoms. But in an atom, most of the volume that it takes up is empty space. So all matter is mostly made up of empty space.
What element is most of the matter in the universe?
The most abundant element in the universe is hydrogen, which makes up about three-quarters of all matter! Helium makes up most of the remaining 25%
How many cones does a luminous flame has?
2, the inner most cone and the outer.
Why do you consider most of outer space empty?
No air
Is most of the universe is empty in space?
yes most of the universe is empty space
What takes most space in a atom?
empty space
What occurs the most in space?
Nothing. That is the most common feature of outer space.
How many people have survived a trip to outer space?
Most people who went into outer space have survived.
Is light faster in gas or in an empty space?
Usually, in most substances the speed of light is slower than in empty space.
What takes most of the room in an atom?
EMPTY SPACE! Over 99% of an atom is empty space. The nucleus is in the center and contains neutrons and protons and this is where most of the mass of an atom is.
Where is most of an atom's empty space found?
electron cloud
What makes up the most the volume of atoms?
Empty space.
What fills most of the size of the solar system?
Empty space.
What fills the space in between gas molecules Is it just empty space?
The space in between gas molecules is not "just empty space." It is filled with constantly moving and colliding molecules. Gas molecules are in constant motion, so even though there may be more space between them compared to liquids or solids, the space is not truly empty.
The space telescope is orbiting in outer space?
There are several, perhaps most notable is the Hubble Space Telescope.
