The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment.
El núcleo atómico es la parte central de un átomo, tiene carga positiva, y concentra más del 99,9 % de la masa total del átomo. 1 . Está formado por protones y neutrones (denominados nucleones) que se mantienen unidos por medio de la interacción nuclear fuerte ,y detallada la cual permite que el núcleo sea estable, a pesar de que los ...
Atom - Proton, Neutron, Nucleus: The constitution of the nucleus was poorly understood at the time because the only known particles were the electron and the proton. It had been established that nuclei are typically about twice as heavy as can be accounted for by protons alone.
Almost all of the mass of an atom is contained within a tiny (and therefore extremely dense) nucleus which carries a positive electric charge whose value identifies each element and is known as the atomic number of the element.
The nucleus (plural, nuclei) is a positively charged region at the center of the atom. It consists of two types of subatomic particles packed tightly together. The particles are protons, which have a positive electric charge, and neutrons, which are neutral in electric charge.
