According to our current understanding of physics, electrons are considered to be fundamental particles and are not thought to possess a specific shape in the traditional sense. In other words, electrons are not considered to be tiny spheres, cubes, or any other geometrical shape.
In quantum mechanics, electrons are described by a wave function, which represents the probability distribution of finding the electron at different locations in space. This wave function describes the electron's behavior in terms of its position, momentum, and other properties. The shape of the wave function can take various forms, depending on the energy level and other factors.
It's important to note that the wave function itself is a mathematical abstraction used to describe the behavior of electrons and other quantum particles. It does not represent a physical shape that can be directly observed. The wave function allows us to calculate probabilities of finding an electron in a particular region of space, but it does not provide a direct visualization of the electron's structure or shape.
