Adhesion, triboelectric effect.
Adhesion (from Latin adhaesio – adhesion, adhesion, attraction),- this is the connection between heterogeneous condensed bodies in their molecular contact. It becomes obvious that the ubiquitous cold-Ch.cl.’s in nature have a decisive influence on this phenomenon. As for the triboelectric effect, there is still no clear explanation for this phenomenon and charge clusters put a lot in their place.
All hot-Ch.cl.’s after the active phase of their existence gradually move into the stable stage of the "cold cluster". At the same time, we have the following picture: a very small electronic crystal of ~ 10^-9 m (about ten atomic diameters) is surrounded by a huge cloud of single-charged gas ions. The deionization potential of such an ion is not enough to detach an electron from the surface of an electronic crystal and thereby begin its disassembly. A powerful electrostatic field tightly presses the nearby ions to the crystal. Further, the ions are arranged more loosely, and thermal motion becomes active. The attracted ions turn out to be orders of magnitude more than in the previous phase of the "hot" cluster. That is, all the conditions for the long-term existence of this, in fact, lump of air appear. In general, the small internal potential energy of these formations remains unclaimed, it cannot be released under normal conditions.
Let's see how the interactions develop between a powerful point negative charge of an electronic crystal, a cloud of single-charged air ions and a solid or liquid surface to which Ch.Cl has a tendency. In electrostatics, the effect of the field is inversely proportional to the square of the distance, therefore, the further the ion shell that shields the point charge extends, the less charge it can have. Shielding refers to the compensation of the electric field of our cluster in a relatively close environment. With more distance, the object will still be perceived as negative and will attract positive ions. Thus, the ion density will decrease with the radius, and at the periphery the ion bond will be very weak. The property of a "cold" cluster to adhere to any solid or liquid surface, regardless of how electropositive or electronegative it will be, can be explained as follows. When the cold-Ch.cl. hits an electropositive surface, for example, a quartz grain, the electronic crystal of the cluster shifts slightly towards this surface, resulting in an electrostatic force of attraction. That is, Ch.cl. is capable of polarization. At the same time, on the opposite side of the cluster, the field weakens and some of the positive ions leave the cluster zone. Now, if the cluster is torn away from the surface by some force, for example, as a result of friction, the number of positive ions in it will be less and it will be negatively charged as a whole. This is the main mechanism of the triboelectric effect. For an electronegative surface, we have a mirror process - the electron crystal moves away from the surface, the cluster attracts additional ions from the surrounding space, and when the particle is detached, it acquires a positive charge. When we rub a glass stick with a silk handkerchief, depleted and enriched with positive ions charge clusters mix, and each side receives a part of the "foreign" particles. When charged bodies are separated, a potential difference arises, which is perceived as triboelectricity.
Static electricity, electrification by friction, thunderstorm manifestations are so common and widespread phenomena that the explanation of their nature with the help of Ch.cl. is alarming. Then we must admit that cold-Ch.cl. clusters are ubiquitous and we are so used to them that we simply do not notice them. Then we must admit that in the nature around us there is a certain excess of electrons over nucleons, because each Ch.cl. contains an E.cr. of electrons, the number of which is orders of magnitude greater than ions. It can be assumed that there is a very small excess of electrons on the surface of our planet compared to the number of protons. The reason for this may be the solar wind. A stream of corpuscles and ions coming from the sun enters the Earth's atmosphere; on the other hand, even more ions and neutral atoms are continuously blown away by the same solar wind from the periphery of the Earth's atmosphere. A certain balance is being formed in terms of the total electrostatic charge of the planet. How will excess electrons behave on the surface of our relatively cold planet if they encounter in their path, in the vast majority of cases, self-sufficient, electrically neutral atoms, molecules and compounds.
