PDF | By means of a general classification of the different kinds of matter of nature form a chain from the world of the subatomic particles to the. The electrical, or electronic, theory postulates that the atoms of solid matter are .. As brought out in the discussion of the general characteristics of the atomic. Matter is anything that has mass and volume. Matter is composed of atoms, which are then composed of "elementary particles": protons, neutrons, and electrons.
Mar 16, All liquids show the following characteristics: Liquids flow from higher to lower level.

How are the particles in a crystalline solid arranged? What properties of liquids are measurable? There are 14 types of lattices, called Bravais lattices named after Auguste Bravais, a 19th-century French physicist , and they are classified into seven crystal systems based on the arrangement of the atoms. The ChemWiki page at the University of California, Davis lists these systems as cubic, hexagonal, tetragonal, rhombohedral, orthorhombic, monoclinic and triclinic.
Aside from the regular arrangement of particles, crystalline solids have several other characteristic properties.
They are generally incompressible, meaning they cannot be compressed into smaller shapes. Because of the repeating geometric structure of the crystal, all the bonds between the particles have equal strength.
This means that a crystalline solid will have a distinct melting point, because applying heat will break all the bonds at the same time. This means that properties such as refractive index how much light bends when passing through the substance , conductivity how well it conducts electricity and tensile strength the force required to break it apart will vary depending on the direction from which a force is applied.
Types of crystalline solids There are four types of crystalline solids: ionic solids, molecular solids, network covalent solids and metallic solids. Because of the strong attraction between opposite charges, it takes a lot of energy to overcome ionic bonds.
This means that ionic compounds have very high melting points, often between and 1, degrees Celsius to 1, degrees Fahrenheit. While the crystals themselves are hard, brittle and nonconductive, most ionic compounds can be dissolved in water, forming a solution of free ions that will conduct electricity. They may be simple binary salts like sodium chloride NaCl , or table salt, where one atom of a metallic element sodium is bonded to one atom of a nonmetallic element chlorine.
Because covalent bonding involves sharing electrons rather than outright transfer of those particles, the shared electrons may spend more time in the electron cloud of the larger atom, causing weak or shifting polarity.
This electrostatic attraction between the two poles dipoles is much weaker than ionic or covalent bonding, so molecular solids tend to be softer than ionic crystals and have lower melting points many will melt at less then C, or F.
Most molecular solids are nonpolar. These nonpolar molecular solids will not dissolve in water, but will dissolve in a nonpolar solvent, such as benzene and octane.
Polar molecular solids, such as sugar, dissolve easily in water.
Another property that can help us identify matter is solubility. Solubility describes how well a substance can be dissolved.
Some substances, like salt, are easily dissolved by water but not easily dissolved by other liquids, like acetone. Acetone is a chemical found in nail polish remover.
Acetone does a great job dissolving nail polish, but it cannot dissolve salt. Density is an important property of matter. Objects with a high density have particles that are more tightly packed than objects with a low density.
To better understand density you can think about the difference between a golf ball and a ping-pong ball. Even though they are about the same size, golf balls are heavier because they have a higher density. How something floats or sinks is also related to its density.
In the video, one balloon was filled with helium and the other was filled with sulfur hexafluoride. The helium balloon went up because its density is less than air.
