What Are The Components of Corn? |
Maize
The concept of the existence of small units that make up matter is known since the time of ancient Greece, even the word atom has existed since that time, but its existence was not proven except by John Dalton in the early eighteenth century, as the atom is the smallest building unit of matter, and its components cannot be separated By any chemical means, examples are atoms; Hydrogen, carbon and zinc, as for chemical compounds, it is possible to break them into smaller parts, which are the atoms. For example, it is possible to break sodium chloride into chlorine and sodium atoms, and it is also possible to see these atoms at the present time using a scanning tunneling microscope . This article will answer a question: What are the components of corn?
What are the components of corn?
To answer the question: "What are the components of an atom?" It can be said that the main components of the atom are three, namely: protons, neutrons and electrons, so that the protons and neutrons are concentrated in the nucleus, and they are linked to each other through the nuclear binding forces that can overcome the electrical forces that may in turn cause the protons to repel each other, and this repulsion is why unstable atoms exist; As the nuclear bonding forces vary according to the size of the atoms, as large atoms are usually unstable, the larger their size, the greater the repulsion force, and therefore these bonding forces cannot overcome the repulsion, and that is why unstable atoms decay into other elements, for example, isotope decays Carbon 14 to the isotope nitrogen 14.
protons
The first atom components are protons which are positive particles charge, was discovered by Rutherford, a mass slightly smaller than the neutrons so that mass for neutrons are 0.9986, while the actual mass is equal to 1.673 * 10 -27 , has been used as the number of protons in atoms to determine the elements, For example, carbon atoms contain 6 protons, oxygen 8 protons, and so on. This number also determines the chemical behavior of atoms of elements. This number of protons is known as the atomic number on which the elements were arranged in the periodic table. A proton consists of 3 quarks; Two each carry two thirds of a positive charge and one one carries one third of a negative charge, so that their sum equals +1 which is the charge of the proton, and these quarks are bound together by massless particles called gluons.
neutrons
Neutrons are uncharged particles discovered by Rutherford in 1920, and the physical mass of a neutron is 1.6749 * 10 -27 , and the masses of protons and electrons are usually compared to the mass of the neutron, which made it have a relative mass equal to 1, and neutrons are found in all nuclei of elements except for Hydrogen 1, whose nucleus contains one proton, and neutrons are also made of 3 quarks; Two, each carrying one-third of a negative charge, and the last one carrying two-thirds of a negative charge, so that their sum equals zero to give the neutron its neutral charge.
Electrons
The most important thing that can be detailed in answering the question: "What are the components of an atom?" is electrons; Electrons have a negative charge that is attracted to the protons inside the nucleus according to the laws of electrostatic attraction, and it was discovered by the British physicist Thomson, and it has a very small mass, as it is 1800 times smaller compared to protons and neutrons, so its mass is 9.109 * 10 -31 , and there are Electrons inside orbits surround the nucleus in the form of a cloud so that the orbits near it are spherical while the outer orbits are more complex, and the model of the electron cloud is an idea put forward by the Austrian science Erwin Schrödinger, and it is possible to distribute electrons in their orbits around the nucleus so that the important orbit is the outer orbit that makes It is easy to predict the properties of atoms such as their stability, boiling point, and conductivity.
secondary components of corn
There are a number of secondary components of atoms of elements that are often emitted during the radioactive decay process, and these secondary components include alpha particles and beta particles, and it is worth noting that gamma rays that are emitted during some types of radioactive decay are not considered particles at all, and the following is a simple explanation of alpha particles Beta:
- Alpha particles: symbolized by the symbol α, they are helium nuclei that consist of two protons and two neutrons, which are emitted from radioactive elements with large unstable nuclei to turn into other, more stable elements. But if the source of their emission is from inside the body, they cause great harm, and these particles are used in the manufacture of artificial defibrillators.
- Beta particles: symbolized by the symbol β, and they are free electrons or positrons with high energy and speed, so that positrons have the same mass as electrons, but they have a positive charge, and beta particles have the ability to penetrate objects a thousand times more than alpha particles, and therefore they cause Significant damage to the structure of living organisms may cause a number of cancers and may lead to death, and despite its harmful effects, it is used in radiotherapy for cancers.
The role of the components of the atom in chemical reactions
After knowing the answer to the question: "What are the components of corn?" Its importance can be identified, and since the atom consists of the nucleus and the electrons surrounding it, so these electrons are the most important components of the atom during chemical reactions between the atoms of the different elements, as these electrons are arranged in orbits around the nucleus and each orbit of them accommodates a specific number of electrons These orbitals are filled from the inside out with electrons, but the electrons that participate in the reactions are in the last orbit only, they determine the behavior of the atom, either the atom gains or loses electrons to form ionic bonds or shares them with other atoms to form covalent bonds .
How did the components of corn originate?
It is expected that atoms arose after the Big Bang that resulted in the entire universe 13.7 billion years ago, after the new universe cooled, conditions became suitable for the emergence of quarks and electrons, so that quarks gathered together to form protons and neutrons that merged in the nuclei in the first minutes of the universe's existence to form The components of the atom, as for the electrons, were formed after 380,000 years, as the universe lost enough heat that reduced the speed of the electrons to a degree that enabled the nuclei to capture these electrons to form the first atoms, and these first atoms are hydrogen and helium atoms , which remained the most prevalent elements in the universe at the present time. As for the heavier atoms, they arose and are still being created as a result of the agglomeration of gases in the stars due to gravity, and when the star explodes, these atoms are distributed throughout the entire universe.
