No, electron clouds have many different strange shapes.
Also being quantum phenomena the identified shape is actually a probability cloud defining where 50% of the electrons will be found, the other 50% of the electrons will be found outside that cloud.
It is shaped like a Sphere
The "shape" of an electron cloud is the surface of equal probability for electrons of a given energy. The shapes can be calculated from the Schrödinger equation. Being quantum phenomena, the identified shape is actually a probability cloud defining the volume within which 50% of the electrons will be found, the other 50% of the electrons will be found outside that cloud. Electron clouds have many different strange shapes. The simplest electron clouds are the clouds for the s orbitals, which are spherical - so in that case - no, the s-orbital electron cloud is NOT shaped like a drop (although you would expect the nucleus to be at its center) There are three perpendicular electron clouds for the p orbitals, which are roughly hourglass shaped - or, if you will, two blobs that mirror each other across the nucleus - not exactly drop shaped. The five electron clouds for the d orbitals and the seven electron clouds for the f orbitals become progressively harder to describe in words but all have portions that could be described as "tear-drop" shaped with the narrow end pointing towards the nucleus.
A cube is "cube" shaped like a square box.
Some examples of irregular shaped objects include rocks, branches, cloud formations, and coastlines. These objects do not have a consistent or symmetrical shape like a sphere or cube.
Rectangular prism
plant cell
Go on google and tipe in cube on images. The image that comes up is a cube.
a cube, postit notes
Some roleplaying game die and puzzles such as the Rubik's Cube are shaped like tetrahedrons.
nothing
It is a cloud that is shaped like a bunny
no its more of a rectangular prism
