The particles found in the nucleus of an atom remain the same in number: proton and neutrons.
This statement might be a good definition of a chemical compound.
covalent bonds a bond (any type of bond, but JUST the word bond!)
Yes, atoms have a definite volume.
An example of a compound that has definite properties is water, which always consists of two hydrogen atoms and one oxygen atom in a fixed ratio.
A fixed quantity of liquid at a fixed temperature and pressure.
A simple definition is: a chemical compond has the elemental components in a fixed ratio.
They are made of gas, obviously, and not dirt; They all contain rings; they have deep, massive, atmospheres.
liquid
Yes, atoms that are held closely together in a regular arrangement form a solid. The strong forces of attraction between the atoms keep them in a fixed position, giving solids a definite shape and volume.
Solids are made up of particles (atoms, ions, or molecules) that are packed close together in a fixed arrangement. The particles in solids vibrate about fixed positions, leading to a definite shape and volume.
If francium could be obtained in large quantities would have a definite volume.
A solid has a definite shape because its particles are closely packed in a fixed arrangement. This fixed structure gives solids a specific shape that remains constant unless acted upon by an external force.
