Chemical Forces Between Particles ~ Cohesion from Latin cohaesiō cling or unity or cohesive attraction or cohesive force is the action or property of like molecules sticking together being mutually attractiveIt is an intrinsic property of a substance that is caused by the shape and structure of its molecules which makes the distribution of surrounding electrons irregular when molecules get close to one another. Electrostatic stabilization and steric stabilization are the two main mechanisms for stabilization against aggregation. If the forces between particles are strong enough the substance is a liquid or if stronger a solid. Atoms or ionsIntermolecular forces are weak relative to intramolecular forces the forces which hold a molecule together. Solids can be classified according to the nature of the bonding between their atomic or molecular components. Aggregation is due to the sum of the interaction forces between particles. The Van der Waals force quickly vanishes at longer distances between interacting molecules. Forces between new neighbouring particles will produce only slight recovery when the deforming force is removed and the material has a new shape. If attractive forces such as van der Waals forces prevail over the repulsive ones such as the electrostatic ones particles aggregate in clusters. Can vibrate in a fixed position. Indeed recently is being sought by users around us, maybe one of you. People are now accustomed to using the net in gadgets to view image and video information for inspiration, and according to the name of the article I will discuss about Chemical Forces Between Particles. Coulombic forces image-charge forces and space charge forces. Covalent bonding which forms network covalent solids Ionic bonding which forms ionic solids Metallic bonding which forms metallic solids Weak inter molecular bonding which forms molecular solids Typical members of these classes have distinctive electron distributions thermodynamic electronic and mechanical propert. As a result solids have a definite shape and volume. If attractive forces such as van der Waals forces prevail over the repulsive ones such as the electrostatic ones particles aggregate in clusters. A chemical bond is a lasting attraction between atoms ions or molecules that enables the formation of chemical compounds. Solids can be classified according to the nature of the bonding between their atomic or molecular components. In boiling bubbles of gas form throughout the liquid. The table shows some of the properties of gases and why they are like this. In evaporation particles leave a liquid from its surface only. Most solids are hard but some like waxes are relatively soft.
Atoms or ionsIntermolecular forces are weak relative to intramolecular forces the forces which hold a molecule together. Coulombic forces image-charge forces and space charge forces. In this paper using a self-consistent field approach a simple theory is developed which allows for the calculation of the bridging force between two plates and two colloidal particles.
For example the covalent bond involving.
The traditional classification distinguishes four kinds of bonding. As a result solids have a definite shape and volume. Aggregation is due to the sum of the interaction forces between particles. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.
