What happens if something is smaller than an atom?
In physical sciences, a subatomic particle is a particle that is smaller than an atom. Particle physics and nuclear physics study these particles and how they interact. Experiments show that light could behave like a stream of particles (called photons) as well as exhibiting wave-like properties.
How many times smaller is an atom than a human?
Everything around us is made up of atoms. An atom is a million times smaller than the thickest human hair….Diameter of an Atom.

What happens to an atom over time?
Since an atom has a finite number of protons and neutrons, it will generally emit particles until it gets to a point where its half-life is so long, it is effectively stable. It undergoes something known as “alpha decay,” and it’s half-life is over a billion times longer than the current estimated age of the universe.
Does atoms have to do with physics?
atomic physics, the scientific study of the structure of the atom, its energy states, and its interactions with other particles and with electric and magnetic fields. Atomic physics has proved to be a spectacularly successful application of quantum mechanics, which is one of the cornerstones of modern physics.
Can you go smaller than atoms?
That list includes quarks, gluons, electrons and neutrinos. Then there are the forces that join those things up: light is one of them. Light is carried by little particles called photons. And there is the Higgs boson particle, which we found last year, which is also smaller than an atom.
What’s smaller than atoms?
Thus, protons and neutrons are no more indivisible than atoms are; indeed, they contain still smaller particles, which are called quarks. Quarks are as small as or smaller than physicists can measure.
Why have ideas of atoms changed over time?
The atomic theory has changed over time as new technologies have become available. Scientific knowledge builds on past research and experimentation. 400 B.C. Democritus, a philosopher in ancient Greece, began the search for a description of matter.
Why did atomic theory change with time?
In general, why did atomic theory change with time? Because more experiments gave more data, theories and models for atoms changed to be more accurate over time. Bohr said that the electrons (the negative particles) move around the nucleus of the atom like planets orbiting a sun, in a set path.
