Who described the atom to be like plum pudding?
That would be Thomson
Who described atoms as being like plum pudding?
J.J. Thompson
Who described the atom as being like plum?
J.J. Thompson
How did Thompson explain the over all neutral charge of the atom?
Hepostulated (he was wrong) the existence of a 'sticky' substance like pudding that had a positive charge that the electrons was stuck in. Like plum pudding. Electrons were like plums actual particles with negative charges. The pudding was just a smear of stuff with a positive charge and held the atom together.
Which item best represents Thompsons mental image of an atom?
Thompson described his model as plum pudding. Since not many people even know what plum pudding is, i like to describe his model as a scoop of chocolate chip ice cream. Imagine the vanilla ice cream as the positive material and the chips as the negative material.
Who said that electrons are mixed evenly throughout the atom like plum pudding?
J J Thomson
Why is plum-pudding and raisin bread a good comparison when talking about JJ Thomson's model of the atom?
Thomson believed that electrons were attached to the nucleus like plums in pudding or raisins in bread.
Describe the plum-pudding model of the atom?
A Description of electrons scattered inside the atom
What is the plum pudding model and who come up with it?
The plum pudding model suggested that the electrons were dispersed throughout the atom (like chocolate chips in a cookie) and the space was positively charged so that in the end the atom was neutral. Today, people know that the electrons are in a "cloud" around the atom and the protons (and neutrons) are in the nucleus, at the center of the atom.
What was the plum-pudding atomic model?
The plum pudding model of the atom, forwarded by J.J. Thomson, stated that the atom was like a plum pudding. The negatively charged electrons were evenly distributed throughout a positive "web" or "soup" much like plums in plum pudding are distributed here and there in the pudding. It was Rutherford, based on his observations with the gold foil experiment, who was able to push this theory aside and cause a shift in thinking to the idea that most of the mass of the atom was concentrated in a small volume within a given atom.
What did jj Thomson think the atom looked like?
Plum pudding. . .with negatively charged rasins and positivly charged blob
How did J.J. Thomson's discovery affect the model of the atom?
J.J. Thomson is credited with the discovery of the electron in about 1904. He envisioned negatively charged "corpuscles" floating in a positively charged cloud, just like plums in a plum pudding. This was the "plum pudding" model of the atom, and it lasted until Geiger and Marsden conducted their gold foil experiment in about 1909.
