What is a positive charge?

Everything in the world, whether natural or synthetic, consists of small structures called atoms that are made of protons, neutrons and electrons. The protons have a positive charge, neutrons do not have charges and electrons have a negative charge. The balance of these particles determines the overall charge of the atom. An object with a positive charge, such as a person after an intense third socks on the carpet, contains more positive particles (protons) than negative (electrons). Because positive atoms are attracted by negative and repelled by other positives, accusations of atoms that make up a piece of matter, strongly affect its properties and behavior.

Atomic hubs

atoms that are the basic unit of matter have a core composed of protons and neutrons around which one or more electrons are bound. The number of protons determines what element is atom and is given as its atomic number. For example, magnesium has 12 protons, giving it 12, while oxygen has eight. When the atoms come together, they become molecules. This means that the answerThe number of protons and electrons is canceled from the point of view of the total charge. Because neutrons are neutral, their number does not affect the charge of the atom.

Although the total number of subatomical particles of the atom changes, atoms are usually electrically balanced, with the same number of protons and electrons. This means that atoms have a naturally neutral charge, but this may change by obtaining or losing electrons through chemical and physical processes. When the electron is lost, the balance moves with the extra proton, giving the atom a positive charge. The opposite applies to the negatively charged atoms that have received an electron. When particles are disturbed, which provides either positive or negative atom (or molecule) that no atoms are called. Instead, there are ions , with positive cations and negatively called anions .

charging and behavior

fee that objectIt affects how it reacts to its environment. For example, cations are attracted to anions, but are repelled by other cations. Similarly negatively charged atoms repel each other. This behavior is referred to as Coulomb's law.

Positive atoms do not attract or reflect neutral, but through a phenomenon called electrostatic induction, attraction can be created. This happens because electrons in some molecules tend to be mobile when the positive charge is close. The electrons in the neutral molecule are then able to move towards the source of a positive charge. The movement creates a negative charge at the nearest point of the source, although the molecule has not changed overall. This phenomenon most often happens with metals, allowing to flow through electric charge.

daily application

many everyday items and processes use positive fees. For example, when the laundry falls in a dryer of clothing, the movement causes electrons to move from atoms on the surface of some objects to jIné and give pieces of clothing different ammunition. This is what leads to static adhesion, because now positively and negatively charged particles are attracted to each other and cause the clothes to hold together. Dryer leaves usually contain chemicals that have a positive charge that has wiped the items, helping to re -neutral.

Another example is a laser printer that prints text and images on paper by creating a number of positive and negative rounds. When the press work begins, the laser "writes" by the transfer of negatively charged status electricity to a cylinder with a positive charge. The toner, which is also positive, is then applied to the cylinder and is attracted to negative areas. The cylinder then rolls over the leaf of a negatively charged paper and the toner is bound to it.

biological molecules

The combined sum of all atoms and ions that are part of the biological molecule are called its pure charge. Most molecules are generally neutral but great tend to have one nEbo more discrete areas that show a negative or positive charge. These areas strongly affect the way the molecule consists and the way it interacts with other molecules. For example, DNA and RNA are nucleic acids, but they behave very differently partially, because their hubs are distributed differently along their surfaces.

Scientific research often requires information about fees of atoms and molecules because it affects how biologically active molecules behave. One particular area where the manipuvant of molecular cartridges is very useful, is in a rational drug design. Scientists in this area are working on the development of more efficient drugs, in some cases manipulating a potential drug charge to be more efficiently interaction with the aim.
