Corn in the service of agriculture
Matter is composed of molecules, molecules are composed of elements, and elements are composed of atoms. Accordingly, it can be said that the atom is the unit of the element. The atom consists of a nucleus (nucleus) in which the weight of the atom is concentrated. A number of electrons revolve around this nucleus in external surroundings, the weight of which is considered small. Very high relative to the weight of the atomic nucleus, and these electrons are all negatively charged. The nucleus of the atom consists of a number of protons and a number of neutrons. The proton is a relatively small, heavy particle, loaded with a positive electrical charge, while the neutron weighs approximately the same as the weight of a proton and is electrically neutral. The hydrogen atom is considered the simplest of atoms, and consists of one proton. And in its outer circle there is one electron.
