In the early years of the twentieth century, atoms were still theoretical entities. Strong circumstantial evidence suggested that atoms existed, but no one had ever actually seen an atom. Today, we can not only see individual atoms on surfaces-we can also move them from place to place, and build things from them.s the tip is dragged over an atom on the surface, more electrons tunnel and the needle is rigged so that the increase in current causes the tip to move up. As the tip is dragged off the atom, the distance between the tip and the surface widens, causing a decrease in current which moves the tip down.
Best Answer: Atoms DO have electric charges. There is a collection of positively charged particles in the nucleus, and a collection of negatively charged particles surrounding the nucleus. So you see that atoms do have electric charges. But, in a neutral atom the magnitude of these opposite charges are identical, giving a net charge of zero. You see, atoms do have charges, but the NET charge is zero. An atom is composed of three types of particles. An electron which is has a measured charge of -1, a proton which has a measured charge of +1, and a neutron which has no electrical charge. The protons and neutrons in an atom are located in a dense nucleus in the center of a spherical atom.
