Talking about atomic structure requires understanding some complicated issues because this topic involves numerous scientific concepts. Still, there are ways of making sense of it. One needs to know about proper sources of information and ways of explaining the phenomenon of atomic structure to achieve greater success.
Importance of Studying the Construction of Atoms
It is important to understand how atoms look like. This topic is rather significant for various fields of science, such as chemistry, physics, and biology.
Components of the Atom
There are three main elements of an atom, and they include protons, neutrons, and electrons. The first two components create the nucleus of the atom, which might be considered the core of it. The other component (electrons) is located around the core.
All three elements are special because they have certain differences concerning charge. Thus, while protons are positively charged and neutrons are neutral, electrons have a negative charge. Furthermore, the quantity of protons determines the atomic number, which, in turn, refers to the element. Different numbers of neutrons mean different isotopes of the element.
Structure of the Atom’s Nucleus That Includes Protons and Neutrons
The nucleus of an atom consists of two elements (protons and neutrons). They are called nucleons. These elements attract each other and stay close because they have positive charges. As far as protons determine the element, and neutrons are responsible for the mass of the element, the changes in the number of protons will lead to changing the element, while the increase or reduction in the number of neutrons will lead only to change in mass of the element.
When an element gets or loses protons in the nucleus, its name changes. For example, there are 11 protons in the nucleus of sodium. If a sodium atom gains one proton, it will become magnesium, while if it loses one proton, the atom will become neon.
Arrangement of Electrons in Orbits Located Around the Nucleus
Negative electrons orbit the atom’s nucleus. They are located in the so-called shells that can contain a definite number of electrons. There is a maximum quantity of electrons per shell, and the final one is referred to as a valence shell. This shell is important because it determines the chemical properties of an element.
Electrons can be depicted via electron configurations. They are represented by symbols that show where electrons can be found. For instance, carbon can be represented by the electron configuration as follows: 1s² 2s² 2p².
Electron Shells and Subshells
Electron shells and subshells are extremely important for understanding the atomic structure. Electron shells denote energy levels at which electrons are located. Subshells are also important since they indicate how many electrons are located inside each shell.
Each of four subshells includes a specific number of electrons (s-orbital – 2, p-orbital – 6, d-orbital – 10, f-orbital – 14).
Atomic Orbitals and Wave Function
Atomic orbitals are functions that define the possibility to find certain electrons near the nucleus. These orbits might be depicted via the electron cloud diagram. Besides atomic orbitals, there is also the wave function of atoms that explains the movement of electrons.
Thus, by studying atomic orbitals and wave functions, scientists receive additional information about the behavior of electrons.
Application of Knowledge About Atomic Structure to Practice
There are numerous spheres of using the acquired knowledge about atomic structure. It is essential in case one wishes to understand chemical and physical phenomena. Moreover, it is useful in studying the behavior and interaction of biomolecules in the biological environment.
Other areas in which knowledge of the subject is applicable are materials science and nanotechnology. In the medical field, the concept under discussion is rather popular as well.
Conclusion and Further Research
As far as conclusion is concerned, one should state that the knowledge about atomic structure is extremely important for analysis of elements’ properties and behavior. There are different numbers of protons, neutrons, and electrons that define the characteristic features of an element.
Still, it is possible to make further researches related to the topic. In this way, it will be possible to receive new facts about atoms and elements.
