In Hydrogen atom, in center Proton and Electron revolving it. My question, is that enclosed in a cell, actually what we see in electron microscope.

The picture of H-atom is a Hazy blob of different density- the centre being darker is seen by electron microscpe.nilesh_pat said:In Hydrogen atom, in center Proton and Electron revolving it. My question, is that enclosed in a cell, actually what we see in electron microscope.

The H-atom is a quantum state -a bound state of electron with a proton as nucleus- the Bohr model is an idealized model only where one pictures the electron as rotating around the nucleus. In reality the electron can have finite probability of staying in the space surrounding the nucleus - no doubt the maximum probability is at a distance equal to the radius of the atom. the size of H-atom is around 0.5 angstrom.
there are some recent techniques which leads to pictures which show the electron cloud having shapes different for different states of the atomic electrons as reported in literature; i will try to look up.nilesh_pat said:In case of heavy metals which has , s,p,d,f cell. what we see in electron microscope.

An electron microscope is a scientific instrument that uses a beam of highly energetic electrons to examine objects at a much higher magnification and resolution than a traditional light microscope.
An electron microscope uses a beam of electrons instead of light to produce an image. When the electrons hit the sample, they interact with the atoms and create signals that are used to form the image.
Atoms are extremely small, with most being less than one nanometer in size. Traditional light microscopes use light waves, which have a much larger wavelength and are unable to distinguish individual atoms. Electron microscopes use electrons, which have a much smaller wavelength and are capable of visualizing atoms.
Yes, some electron microscopes have the capability to capture 3D images of atoms. This is done by tilting the sample and capturing images from different angles, which are then reconstructed into a 3D model.
The main limitation of using an electron microscope to image atoms is the preparation of the sample. The sample must be extremely thin and must be placed in a vacuum to prevent interference from air molecules. Additionally, the electron beam can damage the sample, limiting the amount of time the sample can be observed.
