#Erwin schrodinger atom model series#
Stranger Things is the original Netflix series created in 2016 by two brothers - Matt and Ross Duffer. Also includes some Lumax (Max and Lucas) and Jancy (Jonathan and Nancy), as well as relationships with original characters. Mike lies in bed thinking of how much his life has changed in the past 16 months.
What is the quantum mechanical model of the atom?Īns: The quantum mechanical model of the atom describes the electron as a three-dimensional wave in the electronic field of the positively charged nucleus. What does the quantum mechanical view of the atom require?Īns:The quantum mechanical model of the atom is based on the dual nature of the electron that is, an electron behaves like a particle as well as a wave.
What is the importance of the quantum mechanical model?Īns:The importance of the quantum mechanical model is to understand chemistry because it explains how electrons exist in atoms and how they determine the chemical and physical properties of the elements. From the value of at different points within the atom, one can predict the region around the nucleus where the electron will be most probably found or located. The probability of finding an electron at a point in an atom is proportional to the square of the wave function, i.e., It is also called probability density and is positive. The electron has definite energy in each orbital, and it cannot have more than two electrons.ĥ. Since a number of such waves functions are possible for an electron, the corresponding atomic orbitals are also possible. The atomic orbital is represented by the wave function which is also known as the orbital wave function. This aspect has ultimately led to the concept of atomic orbitals.Ĥ. Therefore, the path of the electron is only probable and not exact. The exact position and the exact velocity (or momentum) of an electron cannot be determined simultaneously. The quantized energy levels in which electrons can be present are obtained from the solutions of the Schrodinger wave equation.ģ. The energy of the electrons in an atom is quantized, i.e., it can have only certain specific values.Ģ. What are the features of the quantum mechanical model of the atom?Īns:The features of the Quantum Mechanical Model of an atom are as follows-ġ. When was the quantum mechanical model of atom created?Īns:In \(1926,\) Erwin Schrodinger developed the quantum mechanical model of the atom, considering both the wave and particle nature of the electron. We discussed the quantum mechanical model atom orbital and the salient features of the model. Also, we learned about the reason for the failure of Bohr’s Model of Atom and how the Quantum Mechanical model explains the dual nature of an electron through Schrodinger’s equation. Through this article, we studied the quantum mechanical model of atom definition, the Dual nature of matter and Heisenberg’s uncertainty principle. Every object which possesses a mass and a velocity behaves both as a particle and as a wave.Īccording to de-Broglie, the wavelength \(\lambda \) of a particle of mass \(m,\) moving with a velocity \(\) at different points within the atom, one can predict the region around the nucleus where the electron will be most probably found or located Louis De-Broglie suggested that all material objects show a dual nature. Hence, it should be a particle, and at the same time, it can be diffracted in the same way as light waves, which are only possible when electrons have a wave nature. An electron has mass and possesses kinetic energy. An electron behaves both as a particle and as a wave. The properties of electrons indicate that they have a dual nature.
