The basic makeup of an atom
WebJan 17, 2024 · Atomic structure is the structure of an atom that consists of a nucleus (the centre), protons (positively charged), and neutrons (neutral). The electrons are negatively charged particles that orbit the nucleus’s centre. Democritus came up with the concept that matter is composed of atoms. John Dalton, in 1800 proposed the first scientific ... WebAtoms are the extremely small particles that are the basic building blocks of ordinary matter. Atoms can join together to form molecules , which make up most objects. Different elements (e.g. oxygen, carbon, uranium) are made up of different types of atoms. An atom is the smallest unit of an element that will behave as that element.

WebThe atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu. By definition, an atom of carbon with six neutrons, carbon-12, has an atomic mass of 12 amu. Other atoms … WebMost metals, however, have electrons that can detach from their atoms and zip around. These are called free electrons. The loose electrons make it easy for electricity to flow through these materials, so they're known as electrical conductors. They conduct electricity. The moving electrons transmit electrical energy from one point to another.
