A. the atom is like a uniform sphere.
b. Cathode rays are made up of electrons.
c. All atoms undergo radioacitve decay.
d. Isotopes undergo radioactive decay.
The answer is A!
The atom is like a uniform spere!
A model is to show something and it does not have a control group, like a experiment.
Niels Borh, a Danish scientist, discovered this in 1913
coorelation
An experiment must have a control to show what would happen if no factors were changed.
This classic diffraction experiment was conducted in 1911.
J.J Thomson's made a A cathode ray tube. This is a tube that is hollow and is sealed.
Thomson set out to prove that the cathode rays produced from the cathode were actually a stream of negatively charged particles called electrons.
JJ Thomson's model of the atom is called the "plum pudding model." It suggested that atoms were made up of positive and negative charges distributed throughout a neutral, positively-charged background.
from his cathode ray tube experiment
JJ moved to 92.5 as an afternoon drive announcer.
sir jj thomsons was a brialiant english physics scientist, he observed the cathod in atom, later called electron, by CRT CATHOD RAY TUBE
yes, he discovered electrons.
Thomsons Online Benefits was created in 2000.
The area of Thomsons Lake is 5,380,000.0 square meters.
it was electrons
Thompson observed that these rays are negatively electrically charged.
JJ Thomson's 1904 model was called the "plum pudding model." This model described the atom as a sphere of positive charge with electrons embedded throughout, like plums in a pudding. It was later replaced by the more accurate Rutherford model.
