How could you modify Rutherford's experimental procedure to determine the relative sizes of different nuclei?

Most alpha particles could move through the foil with little or no interference because of the empty space that makes up most of the atom. However, if an alpha particle made a direct hit on the nucleus of a gold atom, which has 79 protons, the alpha particle would be strongly repelled and bounce back.

A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
These conclusions are derived from the well known gold foil experiment and from other experiments of Rutherford and his collaborators.

Why is experimenral value different from literature value in chimestry?
Due to experimental errors and limitations in the procedure done in the laboratory.
How would you modify your procedure if your experimental absorbance is greater than 1?
dilute it
Describe the experimental procedure for determining the formula for a hydrate?
The experimental procedure for determining the formula for a hydrate that the formula for a hydrate is figured by the prefix and the number of water molecules that are in the compounds. For example is a prefix of di- and two water molecules. The formula is CaCl2 * 2H2O. The name for this is Calcium chloride dihydrate.
What is experimentation?
Experimentation is an operation or procedure carried out under controlled conditions in order to discover an unknown effect or law, to test or establish a hypothesis, or to illustrate a known law.
How could you safely determine if a base is stronger than an acid?
There are a few safe ways to determine if a base is stronger than an acid. There are specialized tests that you can buy.
Why should controls be used with each experimental procedure?
So you can validate the results and determine causation.
Why is experimenral value different from literature value in chimestry?
Due to experimental errors and limitations in the procedure done in the laboratory.
What are the dependent and independent variables in a fruit and nut chocolate bar?
Your question isn't valid because you need an experimental procedure in place before you determine the variables.
The experimental procedure in which both the experimenter and subject are unaware of who is in the experimental and who is in the control group is referred to as the?
Double blind experiment.
Why would you use the Tukey-Kramer procedure?
When the means in all the groups are not equal, Tukey-Kramer procedure can help to determine which of the means are significantly different.
Factors that are varied during an experimental procedure are called?
Variables
Why is probability important to a scientist?
Some but not all scientific models are based on the ability to determine the likelihood that a given experimental outcome has happened by chance alone. If you have an accurate understanding of how the variables in the experiment change when nothing in particular is affecting them, then you have a way to establish some confidence that your outcome is the result of your experimental procedure and not the result of purely random events. The experimental 'lingo' is that the researcher has to determine if the 'Null Hypothesis' can be rejected. The Null Hypothesis is that the experimental outcome is not significantly different from what you would expect if the experiment had no effect at all.As an example, if the probability in the natural world is that some event will happen by chance only one tenth of one percent of the time, then when I observe that event as my experimental outcome, I can be reasonably sure that my procedure has brought about the event; it is so unlikely that it happened by chance. It is not perfect, but few scientific procedures are. This also highlights the importance of replicating studies or of doing meta-analyses of experimental data gathered in many experiments to further reduce the likelihood that observed outcomes are nothing more than chance events.
How would you modify your procedure if your experimental absorbance is greater than 1?
dilute it
List the experimental steps in the order in which they are done?
Purpose, hypothesis, procedure, analysis
What is the definition of Experimental value?
the values you actually get when you do the procedure, these are then compared to the standard values
How do you have your criminal history expunged?
The laws of all states are somewhat different you must determine what the procedure is for your particular state.
Scientists use a series of steps during an experiments what are these steps called?
The experimental procedure.
