what are the constants revolving around the electron? E.g. Mass of electron, wavelength of electron, etc.

I think the mass of an electron is negligible because they are so small, and that they behave more as particles than as waves. However, they are so small that they might be able to behave as waves pretty easily. In short I don't think a constant is necessary for the mass of an electron, but I don't know about the "wavelength of an electron" so I hope someone else responds to this post.

The mass of an electron is equal to 9.11 x 10^-31 kg. To find the wavelength of an electron, you would use the de Broglie equation- the wavelength of an electron is not a constant since it depends on the energy of the electron, which is different for electrons occupying different energy levels.

Planck's constant is a significant one you need to remember. The value is 6.262 * 10^-34 J*s.
