Which of the following statements regarding atomic structure is the FALSE one?   A. All of the positive charge is found in the nucleus   B. The overall size of the nucleus is MUCH SMALLER than the size of the atom itself.   C. Electrons are negatively charged   D. Most of the mass of the atom is containing in the electrons   E. The particles found in the nucleus are called protons and neutrons

The number of protons in an atom determines the identity of the atom. What do the number and arrangement of the electrons in an atom determine? What does the number of neutrons in an atom determine?

The Rutherford experiment was performed and its conclusions reached before protons and neutrons were discovered. When they were found, why was it believed that they were in the nucleus of the atom?

Copper (Cu) has an atomic number of 29 and a mass number of 64. One copper atom, therefore, has how many protons? a.27 b.29 c.31 d.35

How are protons and neutrons similar? How are they different?

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.

What is the modern view of the structure of the atom?

Explain the operation of a cathode-ray tube. Describe the deflection of cathode rays by electrically charged plates placed within the cathode-ray tube. What does this imply about cathode rays?

What is the mass number of an atom with 60 protons, 60 electrons, and 75 neutrons? a. 120 b. 135 c. 75 d. 195

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?
