How is Thomson's model based on the experiment of passing alpha particles through the gold foil?
The results of this experiment led to the model of the atom called "Rutherford's model", rather than Thomson's model, which it basically disproved. Some of the alpha particles were deflected in ways that suggested to Rutherford that most of the atom's mass was concentrated in a positively charged "nucleus".
The info collected during an experiment is called?
The information collected during an experiment is called data. This data is used to analyze the results of the experiment and draw conclusions based on the findings.
Who developed the first model of an atom with electrons on the outside?
Ernest Rutherford developed the first nucleus and electron model of the atom. It was based on experiments conducted by Geiger and Marsden.
Who presented the nuclear model of atom first?
Ernest Rutherford proposed the nuclear model of the atom in 1911, based on his gold foil experiment results. He demonstrated that the positive charge of an atom is concentrated in a small nucleus at its center, with electrons orbiting around it.
Who proved protons existed and how on the atomic model?
Ernest Rutherford provided experimental evidence for the existence of protons through his gold foil experiment in which he observed the scattering of alpha particles. Based on the results of this experiment, Rutherford proposed the nuclear model of the atom, where he hypothesized that atoms have a small, dense nucleus containing positively charged protons.

What scientist said most of the mass of the atom is in tiny dense positively charged nucleus?
Ernest Rutherford is the scientist who proposed that most of the mass of an atom is concentrated in a small, dense, positively charged nucleus, based on his gold foil experiment which led to the discovery of the atomic nucleus.
What scientist concluded the nucleus of an atom contains a dense center of positive charge?
Ernest Rutherford is the scientist who concluded that the nucleus of an atom contains a dense center of positive charge. This conclusion was based on the results of his famous gold foil experiment in which he observed the scattering of alpha particles. Rutherford's discovery revolutionized the understanding of atomic structure and laid the foundation for the development of the modern atomic model.
Which part of the scientific method is based on the results of an experiment?
The part of the scientific method that is based on the results of an experiment is drawing conclusions. This step involves analyzing the data collected during the experiment to determine whether the hypothesis is supported or not.
At the end of an experiment the scientist forms a conclusion based on?
They form their conclusion based on the results of their experiment eg. How much the temperature changed
The info collected during an experiment is called?
The information collected during an experiment is called data. This data is used to analyze the results of the experiment and draw conclusions based on the findings.
How is the Rutherford model different from previous models?
Rutherford's model for the atom, based on the Geiger-Marsden experiment results, contained the new features of a relatively high central charge concentrated into a very small volume in comparison to the rest of the atom and with this central volume also containing the bulk of the Atomic Mass of the atom. later this is called as nucleus.
What is the part of an experiment that serves as the point of comparison for the results?
The 'Variable' is the difference in the experiment that acts as the unknown factor. Results are drawn based on what the Variable does. -Vanack
The detailed explanation of the results of an experiment is called the?
Analysis. This involves examining and interpreting the data to draw conclusions based on the results obtained during the experiment.
What are you making when you anticipate the results of a experiment?
When you anticipate the results of an experiment, you are forming a hypothesis about the potential outcome based on your understanding of the variables involved. This helps you prepare for different scenarios and interpret the results effectively.
What did ernest Rutherford?
Ernest Rutherford is perhaps best known for his model of the atom. He developed his own model, based upon his research, to replace Thomson's plum-pudding model.
What is a conclusion that is based on an observation?
A scientist publishes the results of an experiment. Which science skill is this?
