28 de jun. de 2024 · The model fulfilled the condition that the atom was electrically neutral, and supplied the necessary forces within the atom to hold the electrons in equilibrium. The model imitates in a remarkable way the behavior of the atoms of the elements and also suggests a possible explanation of valency.
29 de jun. de 2024 · The conception of the atom underwent a profound transformation with the discovery of the electron in 1897 by J.J. Thomson. In fact, the existence of an atomic constituent made even more urgent and important the need to provide an answer to the questions “How are atoms composed?” and “What structure do they have?”.

19 de jun. de 2024 · Modelo de Thomson. Estas son las características del modelo atómico de Thomson: Es conocido como el “modelo del pudín de pasas”. Propuesto por J.J. Thomson en 1904. Considera al átomo como una esfera positiva de carga uniforme. Los electrones, con carga negativa, están incrustados en la esfera positiva como pasas en un pudín.
16 de jun. de 2024 · Joseph John Thompson. Hoy sabemos que los átomos no son indivisibles, sino que están formados por unas partículas subatómicas, llamadas partículas elementales. Estas se pueden definir como entes físicos más simples que el núcleo atómico, y se considera que son el último constituyente de la materia.
Hace 5 días · Following his discovery of the electron, Thomson proposed a model for the atomic structure in 1904, famously known as the “plum pudding model.” This model suggested that the atom was a sphere of positive charge with negatively charged electrons embedded within it, much like raisins in a pudding.
24 de jun. de 2024 · The physicist J. J. Thomson posed the problem in 1904 after proposing an atomic model, later called the plum pudding model, based on his knowledge of the existence of negatively charged electrons within neutrally-charged atoms.
