Unusual breath odors are common in kids. Typically there isnât anything to worry about, but there are some breath odors that indicate an underlying problem. In children smelly breath that persists throughout the day is most often the result of mouth-breathing, which dries out the mouth and allows the bacteria to grow.
Light is composed of particles called photons, and matter is composed of particles called electrons, protons, neutrons. It's only when the mass of a particle gets small enough that its wavelike properties show up. To help understand all this let's look at how light behaves as a wave and as a particle.
Atoms are made up of protons, neutrons and electrons, also known as subatomic particles. Because an atom is neutral, the number of electrons is equal to the number of protons. Electrons circle the nucleus, which is made up of protons and neutrons. To unlock this lesson you must be a Study.com Member.eutrons are neutral particles. Surrounding the nucleus is a cloud of very small subatomic particles, called electrons. Electrons are negatively-charged particles. But these basic atomic components are by no means the only known subatomic particles.
