9/2/2023 0 Comments Silicon electron configurationNow, finding the number of neutrons in the Silicon atom, Therefore, number of protons in Silicon = Atomic Number of Silicon = 14 In the case of Silicon, the atomic number = 14 The atomic number of an atom is always equal to the number of protons that an atom contains. To draw the Bohr model of silicon we shall first identify the number of atomic species present in this atom.įirst, let us find out the number of protons in the Silicon atom. Silicon is represented by the symbol Si.The electronic configuration of Silicon is 1s 22s 22p 63s 23p 2.The facts that can be derived from it are: The above-shown Silicon box represents its various properties. Silicon belongs to the carbon family and is located in the 14 th group of the Periodic table. The Silicon atom has 14 protons and 14 neutrons, and 14 electrons revolve around its nucleus in three shells viz. The farthest shell or outermost energy level of an atom is called the valence shell and the electrons that are located in this shell are known as valence electrons. When an electron gets excited it jumps from the lower energy level to the higher energy level. The shell closest to the nucleus is said to have the least energy, also known as the ground state while the one located farthest from the nucleus has the maximum amount of energy associated with it. The shells are also known as energy levels. with the lowest value assigned to the shell located closest to the nucleus. Multiple numbers of shells are present in an atom depending upon the number of electrons it contains.Īccording to the Bohr model of the atom, the shells are named as K, L, M, N, etc., or 1, 2, 3, 4, etc. Shells: These are the circular paths surrounding the atoms in which the electrons are said to revolve around the nucleus.As per the Bohr-Rutherford model, the electrons revolve around the nucleus in fixed orbits or shells. Electrons: These are the negatively charged subatomic particles that surround the nucleus of the atom.Neutrons: These are the neutral subatomic particles that are present inside the nucleus.Proton: This name was given by Ernst Rutherford to the positively charged species existing inside the nucleus.It comprises positively charged protons and neutral neutrons. Nucleus: It is the heart of an atom, located right at its center.To understand the atomic structure better we first need to comprehend the different parts and particles that constitute an atom. The different atomic particles such as electrons, protons, and neutrons are shown at their predicted positions. This model is used to illustrate the atomic composition in pictorial form. The Bohr model is also known as the Bohr-Rutherford model as it was developed as a modification of the Rutherford model.
