Webb15 sep. 2024 · The modern atomic theory, proposed about 1803 by the English chemist John Dalton (Figure 4.2. 1 ), is a fundamental concept that states that all elements are composed of atoms. Previously, we defined an atom as the smallest part of an element that maintains the identity of that element. WebbProtons and neutrons form a positively charged nucleus, which is encircled by an electron cloud that is negatively charged. The nucleus, which is the smallest and densest charged particle in existence, is contrasted to lightweight electrons. A positive charge attracts electrons; in an atom, the electrons are held in place by their electric forces.
