Scientists J. J. Thomson and William Thomson (Lord Kelvin) made numerous contributions to our understanding of the atom’s structure. Which subatomic particle did J. J. Thomson discover, and what did this lead him to postulate about the nature of the atom? William Thomson postulated what became known as the “plum pudding” model of the atom’s structure. What did this model suggest?
Do the proton and the neutron have exactly the same mass? How do the masses of the proton and the neutron compare to the mass of the electron? Which particles make the greatest contribution W the mass of an atom? Which particles make the greatest contribution to the chemical properties of an atom?
lton believed that atoms were indivisible. Thomson and Rutherford helped to show that this was not true. What if atoms were indivisible? How would this affect the types of reactions you have learned about in this chapter?
The average atomic masses of some elements may vary, depending upon the sources of their ores. Naturally occurring boron consists of two isotopes with accurately known masses ( 10B, 10.0129 amu and 11B, 11.0931 amu). The actual atomic mass of boron can vary from 10.807 to 10.8 19, depending on whether the mineral source is from Turkey or the United States. Calculate the percent abundances leading to the two values of the average atomic masses of boron from these two countries.
Part ARecall all the models you described in task 1. Think about the results each model would predict for the experiment with hydrogen gas. Which models of the atom does the experimental evidence support? Explain why these models are compatible with the experimental results. Part BWhich models of the atom in task 1 are not supported by the results of the hydrogen gas experiment? For each of these models, explain the experimental results that the model would predict. Models in task 1: - Dalton’s Atomic Model- Thomson’s Atomic Model- Rutherford’s Atomic Model- Bohr’s Atomic Model

You find a new mineral while traveling for Thanksgiving in northern Ontario, Canada. You decide to name the mineral Ontarium. You bring it back to the isotopic analysis lab at the research university where you are earning your bachelor's degree. It is discovered that it contains 7.759 % by mass of of the element oxygen (molar mass 16.00 g/mol). The new element Torontium (To molar mass of 368 g/mol) composes 92.25% of the mass of the formula unit Ontarium. Unfortunately after you have carried this mineral in your pocket, as it glows in the dark and you wanted to show everyone. You are hoping to make a lot of money from this discovery, but you then discover that Torontium is highly radioactive and gives off alpha radiation. You have 100.00 grams of Ontarium. Calculate the MOLES of both Torontium and Oxygen and then calculate the empirical formula which is the simplest integer ratio between the two elements (and also the structure of the formula unit for this ionic compound).
In Section 1.1 of the text, the concept of a chemical reaction was introduced with the example of the decomposition of water, represented as follows: Use ideas from Dalton's atomic theory to explain how the above representation illustrates the law of conservation of mass.
Your friend tells you about an article that he read in a tabloid that reported the discovery of a new form of carbon containing eight protons in the nucleus of its atoms. He claims that scientists are eager to explore the properties of this new form of carbon. What is wrong with the tabloid's claim? a. Nothing. The claim is believable. b. The claim must be false because an atom with eight protons would be oxygen, which is already known. c. The claim must be false because all forms of carbon are already known.
