The 'raisin pudding' model of the atom is more traditionally called the 'plum pudding model'.
The plums represented negatively charged corpuscles (electrons) surrounded by a positively charged pudding.
The plum pudding model became outdated in 1909 - 1911 when experiments showed that the positively charged atoms were extremely small.
What else can I help you with?
Why is plum-pudding and raisin bread a good comparison when talking about JJ Thomson's model of the atom?
Plum pudding and raisin bread are good comparisons for Thomson's model of the atom because both posit a positively charged "pudding" with negatively charged "raisins" embedded within, similar to Thomson's idea of the atom having a "sea" of positive charge with electrons scattered throughout. This analogy helps to illustrate the distribution of charge within the atom proposed by Thomson.
What are the key structural features of Thomson's 'Plum pudding' model?
Thompson's plum pudding model was that the raisin were negatively charged (electrons) and that the rest of the pudding positively charged.
What did the pudding represent in the plum pudding model?
Thomson's plum pudding model is the model of an atom in which an atom is regarded as a sphere of size 10^(-10)m radius and positively charged matter in which electrons were embedded. Thomson used the pudding as the positive charge and the plums as the negative charge. The plums are stuck in the pudding just as electrons are randomly found in an atom.
What is the nickname for Thompson's atomic model?
The nickname for Thompson's atomic model is the "plum pudding model." This model suggests that atoms are made up of a positively charged "pudding" with negatively charged electrons embedded within it, resembling plums in a pudding.
In Thomas plum pudding model of the atom the plugs represent?
The plugs represent the electrons.
In Thomson's plum pudding model what do the plums represent?
The plums represent the electrons, which has a negative charge.
In Thomson and plum-pudding model of the atom the plums represent?
The plums represent negative electrons
In thomson's raisin-bun model what were the electrical charges on the raisins buns?
The charges were the negative charges of the electrons surrounding the nucleus of the atom.
In Thomsons Raisin Bun model what were the electrical charges on the bun and the raisins?
The charge of the negative charge of electrons surrounding the nucleus of the atom.
Who proposed the plum-pudding model of the atom?
J J Thomson
What was the raisin bun theory And why was it called this?
The raisin bun theory is a model of the universe's structure that suggests galaxies are like raisins embedded in a rising dough, representing space itself. As the dough expands, the raisins move away from each other, illustrating how galaxies are receding as the universe expands. It is called the "raisin bun theory" because the analogy of a bun filled with raisins effectively visualizes the distribution of galaxies in an expanding universe. This model helps to explain the observed redshift of distant galaxies as evidence of cosmic expansion.
What scientist atomic model was called the plum pudding model or the chocolate chip cookie dough model?
The scientist who proposed the plum pudding model, also known as the chocolate chip cookie dough model, was J.J. Thomson. In this model, electrons were embedded in a positively charged sphere, much like raisins in a plum pudding or chocolate chips in cookie dough.
