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 part of elements. In other words, each element is made up of atoms. Atoms are made up protons, electrons and neutrons, also called subatomic particles. Together, protons, neutrons and electrons, are called nucleons. Protons, neutrons and electrons are made up of even smaller particles, called quarks. The center of an atom is called a nucleus. The nucleus is pushed together by the strong nuclear force. The nucleus is made up of protons and neutrons. Protons are positively charged and neutrons have no charge. Around the nucleus are electrons.
