Question

According to Schrodinger model, nature of electron in an atom is as:
A.Particles only
B.Wave only
C.Simultaneously both
D.Sometimes wave sometimes particle

Answer 1

Hint: Schrodinger model deals with the nature of electrons present in an atom, after the rejection of Bohr’s model because of certain limitations.
Schrodinger model is the basis of understanding the modern concept of an atom.

Complete step by step answer:
One of the major drawbacks of Bohr's model was that it treated electrons as some particles which existed in precisely-defined orbits. Based on de Broglie's idea that sometimes particles could exhibit wavelike behaviour, the Austrian physicist Erwin Schrödinger came up with a theory that the behaviour of electrons inside atoms could be explained by treating them mathematically as waves of matter. This model, which is now the basis of the modern understanding of the atom, is called the quantum mechanical or the wave mechanical model.
The fact that there are only certain specific allowable states or energies that an electron in an atom can have is similar to a standing wave.
To get a better understanding of electron matter waves let us discuss some properties of standing waves.
As you probably already may have noticed that the stringed musical instruments have standing waves which are being created by playing them. For example, when a string is pulled on a guitar, the string creates vibration in the shape of a standing wave.
On a simpler term, we can think of electrons as matter having standing waves that have certain specific allowed energies. Schrödinger formulated a model regarding the atom that assumed that the electrons could be treated as matter waves.
In the given question the first option says that according to the Schrodinger model the electron in an atom has particle nature only, so this option is not correct as we learned that it has wave nature according to the model.

Hence the correct answer is option B.

Note:
In the question we discussed the wave nature of particles but there is the concept in quantum mechanics called Wave–particle duality, which says that every particle or quantum entity may be described as either a particle or a wave. It expresses the inability of the classical concepts "particle" or "wave" to fully describe the characteristics of quantum-scale objects.
