Are electrons solid particles?

Is a mathematical point without any size or structure “solid?” If it is not, then an electron is not a mathematical point with no size or structure. However, it does have mass and location.

Are you sure a rock is “solid”? Are you sure? You are not sure? If you pay attention, this makes a rock very similar to a vacuum. The attractive and repelling forces between the point particles give rock its “solidity”.
