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.
An atom is the smallest particle of an element which may or may not be capable of independent existence. Dalton's idea of matter is known as John Dalton's atomic theory. Dalton first proposed his atomic theory in 1803. Matter is composed of very tiny indivisible particles called atoms.Atoms are incapable of being destroyed or created.According to Dalton's atomic theory the atom is the basic unit from which matter is constructed.n atom is the smallest particle of an element which may or may not be capable of independent existence.
