How did the results of Rutherfords gold foil experiment differ from his expectations?
Everyone thought that the alpha particles would go through the gold- foil with little deflection. When the alpha particle passed straight through the gold atoms with no deflection or bounced straight back a small fraction bounced off at a large angle, or bounced straight back to the source. Rutherford came up with a new theory of the atom, that the atom is mostly empty space and in the center there is a nucleus. this is known as the nucleus atom.

How did Pasteur's experiment differ from spallanzanis experiment?
Pasteur's experiment refuted the theory of spontaneous generation by demonstrating that microorganisms in broth were killed by heat and could only enter through the air. Spallanzani's experiment involved boiling broth in sealed flasks to prevent microorganism entry, concluding that the lack of spontaneous generation was due to the lack of vital force rather than the absence of air.
What would happen if copper metal was used to conduct Rutherford gold foil experiment?
If copper metal was used instead of gold foil in the Rutherford experiment, the alpha particles would not be scattered as much because copper is not as dense as gold. This would lead to less deflection of the alpha particles, making it difficult to observe the small angle scattering that led to the discovery of the atomic nucleus.
What is the only thing that should differ between experiment treatment?
The only thing that should differ between experimental treatments is the variable being tested or manipulated. All other factors should be kept constant to ensure that any observed differences in outcomes can be attributed solely to the variable being studied.
How do boron -10 and boron -11 differ?
Boron-10 and Boron-11 differ in their number of neutrons. Boron-10 has 5 neutrons, while Boron-11 has 6 neutrons. This mass difference results in different properties and applications for each isotope.
5. How do isotopes differ from one another and from the element atoms on the periodic table?
Isotopes of an element have the same number of protons but different numbers of neutrons. This results in variations in atomic mass for isotopes. The element atoms on the periodic table represent the average mass of all its naturally occurring isotopes.
What must a scientist do if an experiment does not support their hypothesis?
If an experiment does not support a scientist's hypothesis, they should analyze the data to understand why the results differ from their expectations. This may involve examining the experimental design, methodology, or variables involved. The scientist should then consider revising the hypothesis based on the new findings or conducting further experiments to explore the unexpected results. Ultimately, this process contributes to the advancement of knowledge and understanding in the field.
If the results of an experiment turn out differently from what is expected what should be done?
If the results of an experiment differ from expectations, the first step is to carefully analyze the data and review the experimental procedures for any errors or inconsistencies. It's important to consider potential variables that may have influenced the outcomes. After thorough evaluation, researchers should document the findings and, if necessary, conduct additional experiments to explore the unexpected results. Finally, sharing these findings with peers can provide valuable insights and foster further discussion.
Why do scientist use control groups in experiments?
Because it helps them know the results of the objects in the experiment and how they differ. This way the scientist knows which succeeded and which failed.
How do you improve accuracy by controlling the variables more carefully?
Accuracy is how close together your results are each time you repeat an experiment, so keeping the variables as constant as you can ensures your results differ as little as possible.
What is a condition that can differ within an experiment?

How did the actual results of rutherfords gold foil experiments differ from the results he expected?
Rutherford expected that the alpha particles would pass through the gold foil with only minor deflections. However, some alpha particles were deflected at large angles, and a few even bounced back. This result led Rutherford to propose the existence of a small, positively charged nucleus at the center of the atom.
Why are some results from different countries may differ in the strange situation experiment?
Results from the Strange Situation experiment can vary between countries due to cultural differences in parenting practices and attachment styles. For example, countries that prioritize independence may have children who exhibit more avoidant attachment behaviors, while countries that emphasize interdependence may have children who exhibit more secure attachment behaviors. Additionally, factors such as socioeconomic status and family dynamics can also influence the results of the experiment.

How does a good experimental conclusion differ from and inference?
A good experimental conclusion summarizes the findings of an experiment based on data and observations, clearly stating whether the hypothesis was supported or not. In contrast, an inference is a logical interpretation or explanation derived from the data, often extending beyond the immediate results to suggest broader implications or connections. While conclusions are grounded in the specific results of the experiment, inferences may involve assumptions and contextual knowledge that go beyond the experiment itself.
How did the effects of Prohibition differ from its advocates' expectations?
Lawlessness increased rather than decreased.
When a scientist does an experiment and draws a conclusion how does the conclusion differ from a theory?
A conclusion is what the experimenter observes from the experiment andwhether your hypothesis was proven correct or not.While the theory is the facts that is known about the experiment
