Below I have attached a screenshot of the lab questions and procedure.

also include the answer to this question:

Describe the structure of the nuclear atom.

I am also including the link for the rutherford and plum pudding simulation (info on it found in screenshot) below.

Question When a quarter, a nickel, a penny, and a dime are spun on a tabletop, what characteristics allow you to identify the type of spinning coin? Procedure • Hold a quarter up on its edge and flick it with your index finger to set it spinning. Note the appearance and sound of the spinning coin until it comes to a stop on the table. • Repeat step 1 three more times using a dime, a nickel, and a penny, respectively. • Have a partner spin the coins, one at a time, in a random order. Observe each coin only after it is already spinning and then try to identify the type of coin that it is. • Repeat step 3, except this time, keep your eyes closed while listening and trying to identify each of the spinning coins. Analysis: • How successful were you at identifying the individual coins when you were limited to listening to the sounds they made? • What are the characteristics of a spinning coin that can be used to identify its type? • What instruments/equipment might make the identification of the spinning coins easier? Questions • The average mass of an atom of an element is known as ? • The currently accepted model of the atom is that of? • Atoms of an element with the same number of protons but different number of neutrons in the nucleus are known as ? • The smallest particle of an element which can take part in chemical reactions and may or may not exist independently is the ___ Section B Plum Pudding to Classical Solar System - To answer this question do the following: 1. Open the Rutherford simulation below. This simulation gives a microscopic picture of Rutherford's famous experiment in which he shot alpha particles at a thin foil of gold. Rutherford Scattering 2. Based on Thomson's Plum Pudding model, how did Rutherford expect the alpha particles to behave when he shot them at the gold atoms? (To see this behavior, go to the "Plum Pudding Atom" panel of the simulation.) 3. Why did he expect this? 4. What did he observe instead? (Go to the "Rutherford Atom" panel.) 5. Based on his observations, what inference did Rutherford make about the distribution of positive charge in the atom?

Question 1
When a quarterly, a nickel, a penny, and a dime are spun on a tablespoon, what
characteristics allows you to identify the type of spinning coin?
It was not that hard to identify the type of the coin by the noise that it makes. This is
because the coins produce different type of coins. But then a t 1st I didn’t not now ...

This is great! Exactly what I wanted.
