How the particles of matter are arranged in solid?
Solids have a fixed shape as their particles are arranged in a regular, fixed arrangement and they have strong forces holding them together, so the shape of the solid remains fixed. So, the particles in a gas can easily move around and fill the shape of the container they are in, meaning they have no fixed shape.
How are particles arranged and how do they move in a solid?
In a solid, the particles pack together as tightly as possible in a neat and ordered arrangement. The particles are held together too strongly to allow movement from place to place but the particles do vibrate about their position in the structure.
What is the organized arrangement of particles in a solid called?
crystal lattice
In crystalline solids, the atoms, ions or molecules are arranged in an ordered and symmetrical pattern that is repeated over the entire crystal. The smallest repeating structure of a solid is called a unit cell, which is like a brick in a wall. Unit cells combine to form a network called a crystal lattice.
What is the arrangement of particles in matter?
Particles in a: gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
In what three ways can particles in matter be arranged?

In which state of matter do particles have the most energy?
gas
In terms of relative energy, gas particles have the most energy, solid particles have the least energy and liquid particles are somewhere in between. (All compared at the same temperature.)
liquid vibrate, move about, and slide past each other. solid vibrate (jiggle) but generally do not move from place to place. Liquids and solids are often referred to as condensed phasesbecause the particles are very close together.
How are particles held in relation to each other?
There is strong attraction between particles, but not as strong as in solids. Consequently, the particles are tightly packed. The particles are not held in a fixed arrangement as in solids, so are able to slide past each other.
How are particles in a solid well separated?
Microscopic view of a solid. Note that: Particles in a: gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
How are particles in solids attracted to each other?
▸ Are very strongly attracted to each other. ▸ Are closely packed, in a fixed arrangement. ▸ Move by vibrating. ▸ Have medium kinetic energy. ▸ Are strongly attracted to each other. ▸ Are closely packed, in a free arrangement. ▸ Move by sliding past one another. ▸ Have high kinetic energy. ▸ Are not attracted to each other.
