- What evidence led to the conclusion that cathode rays had a negative charge?arrow_forwardIn a reproduction of the Millikan oil-drop experiment, a student obtains the following values for the charges on nine different oil droplets. (a) Based on these data alone, what is your best estimate of the number of electrons on each of the above droplets? (Hint: Begin by considering differences in charges between adjacent data points, and see into what groups these are categorized.) (b) Based on these data alone, what is your best estimate of the charge on the electron? (c) Is it conceivable that the actual charge is half the charge you calculated in (b)? What evidence would help you decide one way or the other?arrow_forwardExplain 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?arrow_forward
- When J. J. Thomson measured the deflection of a stream of electrons in a magnetic field, he was able to demonstrate that electrons were particles, but he was unable to determine the mass of an electron. Explain.arrow_forwardWhich of the following are isotopes of element X, the atomic number for which is 9: 919X, 920X, 189X, and 921X?arrow_forwardIn 1886 Eugene Goldstein observed positively charged particles moving in the opposite direction to electrons in a cathode ray tube (illustrated below). From their mass, he concluded that these particles were formed from residual gas in the tube. For example, if the cathode ray tube contained helium, the canal rays consisted of He+ ions. Describe a process that could lead to these ions. Canal rays. In 1886, Eugene Goldstein detected a stream of particles traveling in the direction opposite to that of the negatively charged cathode rays (electrons). He called this stream of positive particles "canal rays:"arrow_forward
- 2.40 What distinguished the work of Mendeleev that caused scientists to accept his concept of the periodic table when others before him were not believed?arrow_forwardFrom the following written description, write the balanced chemical equation for the reaction including state symbols. A diatomic gaseous molecule that contains 17 protons per atom is reacted with a solid element that has an atomic number of 19 to yield an ionic compound.arrow_forwardDescribe the nuclear model for the atom and identify the numbers of protons, electrons, and neutrons in a particular isotope from its chemical symbol.arrow_forward
- There are 2.619 1022 atoms in 1.000 g of sodium. Assume that sodium atoms are spheres of radius 1.86 and that they are lined up side by side. How many miles in length is the line of sodium atoms?arrow_forwardAn unknown particle is caused to move between two electricallycharged plates, as illustrated in Figure 2.7. You hypothesizethat the particle is a proton. (a) If your hypothesis iscorrect, would the particle be deflected in the same or oppositedirection as the β rays? (b) Would it be deflected by asmaller or larger amount than the β rays?arrow_forward(d) the ion with 74 electrons, 116 neutrons, and a +3 chargearrow_forward
