Also, quantum theories state that electrons probably do not rotate around the nucleus in an orbit. When electric charges move, they create a magnetic field. When the charges change directions, they give off electromagnetic radiation. If electrons rotate in orbits, they would give off such radiation, which they don't. Thus, scientists believe that electrons are stationary in a shell around the nucleus of an atom, perhaps as a cloud. On the other hand, perhaps that radiation rule does not hold when an electron is in an orbit or shell.
But it shows that there is a lot more to what is around us than we realize. Thinking and speculation on this sort of thing can be fun to do. Science fiction writers have used such speculation to write stories and movies for use to enjoy.
Look beyond what is obvious. Examine similarities and trends in order to draw some conclusions or create a theory. That is what science is all about. The Bohr or solar system model of the atom states that atoms consist of a nucleus with a number of electrons in orbits around that nucleus, similar to a solar system.
People have speculated that perhaps atoms are tiny solar systems. Perhaps our own Solar System is similar to the element Oxygen, which has a nucleus and eight smaller electrons rotating around it in their orbits. Likewise, perhaps our solar system is an "atom" in some larger entity. Although recent studies have shown that the Bohr model of the atom is probably not correct or is incomplete, the concept of tiny solar systems has captured the imagination of many people.

Top-rated books on Matter. The Bohr model was close to reality, but it is the simplest way to imagine an atom. Considering a carbon atom as a football field and the nucleus as the marble, one can imagine six electrons would be zooming around in the stadium.
Thus, most of the stadium, i. The image becomes even more peculiar when one realizes that electrons are simultaneously everywhere. Learn more about myths of orbital motion. Electrons are not tiny balls swirling in the atom in their specific circular orbits. As far as the laws of quantum mechanics allow, electrons are simultaneously everywhere in the atom. Conclusively, the atom is almost like Bohr said, but with much more complexity and considerable empty space.
Atoms build everything in our world. Previously, it was assumed that atoms are like small balls, but today the definitions differ. The atom is made up of three main particles , i. All materials are made of atoms.
Thus, atoms are like the building blocks of everything and can combine to make new substances. Hydrogen H is one of the most common atoms. An atom looks like a very small solar system , with the heavy nucleus in the center and the electrons orbiting it. However, the electrons are in layers and can be simultaneously everywhere that quantum allows.
Atoms are like extremely small bricks building any material. An atom is too small to be seen by the human eye. By Don Lincoln, Ph. They have likened it to a plum pudding, a small ball, and even a tiny solar system. Perhaps, it is also imagined as a core with a cloud of small and light particles surrounding it.
Atom images ranged from chocolate chip cookies to solar systems to football fields. The observation confirms a long-sought connection between the quantum and classical realms. According to quantum mechanics, tiny objects like electrons do not have precise trajectories.
Rather, they must be described by quantum waves of probability. Yet the quantum and classical realms must join smoothly, so somehow the rippling quantum waves must be able to mimic a classical trajectory. For example, in researchers flashed laser light on an atom and created a wave packet that orbited the nucleus; however, it spread and faded away in just a few dozen orbits.
But shine microwaves on the atom and the wave packet can last for thousands of orbits, report Haruka Maeda and Thomas Gallagher of the University of Virginia in Charlottesville. The researchers used laser pulses to produce a wave packet that contained the outer electron of a lithium atom and traveled around the nucleus on an elongated elliptical orbit.
They then applied microwaves whose electric field pointed in the same direction as the orbit stretched.
