In a literal sense no, but they have been detected experimentally. The fact that your television works is proof enough that electrons exist, since an electron is required to strike a screen in order to produce an image.
Only the largest of viruses (e.g. Pox viruses) can be seen with a good light microscope (albeit with poor detail). Viruses usually can only be seen by electron microscopy. [2nd year Dental student, Naser]
[Ne]3s1i think but I'm not sure as i haven't seen this before but i know it as 2,8,1
This is the electron.
Electron affinity is the energy released when an atom gains an electron to form a negative ion, while electron gain enthalpy is the enthalpy change accompanying the addition of an electron to a gaseous atom. Electron affinity is a specific term used in the context of forming an ion, while electron gain enthalpy is a general term for the enthalpy change associated with gaining an electron.
According to Wikipedia: Viruses are ancient. Studies at the molecular level have revealed relationships that show viral proteins that pre-date the divergence of life and thus the last universal common ancestor. This indicates that some viruses emerged early in the evolution of life, and that viruses have probably arisen multiple times.
No. If you've seen one electron, you've seen them all.
Yes, you can see molecules and atoms by using an electron microscope. Click the Related Links for a website that has some pictures.

None can. They have to be seen using a electron microscope.

Yes I have seen the tooth fairy in action.
Yes, atoms can be seen through an electron microscope. Electron microscopes use a beam of electrons rather than light to visualize samples at nanoscale resolutions, allowing for direct observation of individual atoms.
Anyone is singular, e.g.Is anyone going to the cinema?Has anyone seen my cd?
Millions have seen the play.
I believe there is no one who has ever seen an angel
The Nucleus is seen through the use of an Optical Microscope and The Mitochondria is seen through an Electron Microscope.
Smaller characteristics of specimens might be seen using electron microscopy to view a dried nonliving specimen. The electron microscope is used to view specimens in great detail.
