This question puzzled us as well;
We know that J J Thomson discovered the electron (by 'bending' Cathode rays off a electric field) and therefore discovered the negative charge on the atom. He then created the plumb pudding model which shows both the positive and negative charge on the atom.
So from this we can see that there must have been an understanding of Atoms and there positive charge before J J Thomson found the sistering negative charge. The nucleus of the atom was already well on its way to being discovered.
Disclaimer: I would however, not use this answer for anything important (Such as H/W projects) because as I said before we ourselves are unsure about this. We are only basing this on concussion and not historic or scientific facts.
What else can I help you with?
Which item best represents thomsons mental image of an atom?
The plum pudding model best represents J.J. Thomson's mental image of an atom. In this model, electrons are embedded within a positively charged "pudding," similar to how seeds are embedded in a watermelon.
Who discovered of oxygen atom?
The discovery of the oxygen atom is credited to the English chemist Joseph Priestley in the late 18th century. Priestley's experiments with various gases led to his isolation and identification of oxygen as a unique element.
Who split the uranium atom first?
enstine found out how to split it but Lisa mieghtner acutally split the atom with her nephew at her side and otto haun claimed that he did but he didnt.(he and Lisa were co workers and when Hitler came (mieghtner was a Jew) he took credit for her work while she feld the country)
When was Discovery Science Center created?
Discovery Science Center was created in 1998.
An atom of chlorine has 6 more protons than an atom of sodium How many protons does an atom of chlorine have?
An atom of chlorine has 17 protons, while an atom of sodium has 11 protons. Therefore, an atom of chlorine has 6 more protons than an atom of sodium.
What were Thomsons and rutherfords key discoverirs about the atom?
im awesome!
How did Rutherfords model of the atom different from thomsons?
The Rutherford model involve a positive nucleus separated from electrons.
What was discovery?
His MAJOR discovery was when he discovered 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.
Which atomic model was proposed as a result of j.j. Thomsons work?
J.J. Thomson's work led to the proposal of the "plum pudding model" of the atom in 1904. In this model, the atom is envisioned as a spherical cloud of positive charge with negatively charged electrons embedded within it, similar to plums in a pudding. This model was an early attempt to describe the internal structure of the atom before the discovery of the nucleus and the later development of the Rutherford and Bohr models.
How did Rutherfords findings change Thomsons plum pudding model?
Rutherford supposed that the atom had a central positive nucleus surrounded by negative electrons.
Alpha particles led to what discovery of what?
discovery of the atom's structure
What is the area of Thomsons Lake?
The area of Thomsons Lake is 5,380,000.0 square meters.
When was Thomsons Online Benefits created?
Thomsons Online Benefits was created in 2000.
Who made the atom?
the ancient Greeks made the atom, but they had no proof after the discovery.
What discovery rejects the idea that atom is indestructible?
Its RADIOACTIVITY!! That was the first discovery that rejects the idea that the atom is indestructible
What were J. J. thomsons ideas called?
J.J. Thomson's ideas were called the plum-pudding model. This model described how electrons were evenly distributed throughout the atom.
