Today's model gives us a much clearer picture of the atom. There is a positively charged center of the atom that is denser than the rest of it called the nucelus. This dense center is made up of positively Thomson atom model . On discharge of electricity through gases, it became clear that an atom consists of positive and negative charges. J.J. Thomson tried to explain the arrangement of positive charge and the electrons inside the atom. According to him, an atom is a sphere of positive charge having a radius of the order of 10-10 m.

Thomson Model of Atom: Thomson model of atom states that electrons are embedded in a positively charged solid material which is spherical in shape. Rutherford Model of Atom: Rutherford model of atom describes that an atom is composed of an atomic nucleus and electrons surrounding the nucleus. The Plum Pudding Model is a model of atomic structure proposed by J.J. Thomson in the late 19th century. Thomson had discovered that atoms are composite objects, made of pieces with positive and negative charge, and that the negatively charged electrons within the atom were very small compared to the entire atom.

JJ Thomson föreslog att överväga atomen, eftersom en viss kropp är positivt Thomsons upptäckt av elektronen och Ernest Rutherfords upptäckt av atomkärnan utgjorde grunden för Niels Bohrs atommodell som används än idag.

%. Progress. Practice Thomson's Atomic Model. MEMORY METER. This indicates how strong in … 2017-06-10 Thomson’s model of an atom is also called the plum pudding model. The plum pudding model is one of the several historical scientific models of the atom. First proposed by J.J. Thomson in 1903 soon after the discovery of the electron but before the discovery of the atomic nucleus.

It has a negative charge of 1.602 × 10-19 C and a mass of 9.1085 × 10-31 kg at rest. Electrons are distributed along with positive charges in the atom in a sphere of radius 10-10 m like a plum in the pudding.

In particular, Bohr was very much influenced by the work of his mentors, Thomson and Rutherford, whom he cited extensively throughout his Trilogy of 1913, in which he introduced the quantum theory of the atom.
