Chapter 1: Problem 39

In an experiment it was found that the total charge on an oil drop was \(5.93 \times 10^{-18} \mathrm{C}\). How many negative charges does the drop contain?

Short Answer

Expert verified
The oil drop contains approximately 37 negative charges (electrons).

Step by step solution

01

Identify given values

We are given the total charge on the oil drop (\(Q\)) and the charge of an electron (\(e\)). - Total charge on the oil drop (\(Q\)) = \(5.93 \times 10^{-18} \mathrm{C}\) - Charge of an electron (\(e\)) = \(1.60 \times 10^{-19} \mathrm{C}\)
02

Use the formula to find the number of negative charges

We'll divide the total charge (\(Q\)) by the charge of a single electron (\(e\)) to find the number of negative charges (electrons) on the oil drop: Number of negative charges (\(n\)) = \(\frac{Q}{e}\)
03

Calculate the number of negative charges

Plug the given values into the formula: \(n = \dfrac{5.93 \times 10^{-18} \mathrm{C}}{1.60 \times 10^{-19} \mathrm{C}}\) Now, we'll perform the calculation: \(n = 37.06\)
04

Round the result and state the final answer

Since the number of negative charges must be a whole number, we'll round the result to the nearest whole number: \(n \approx 37\) Hence, the oil drop contains approximately 37 negative charges (electrons).

What is the symbol for an ion with 63 protons, 60 electrons, and 88 neutrons? If an ion contains 50 protons, 68 neutrons, and 48 electrons, what is its symbol?

Which (if any) of the following can be determined by knowing the number of protons in a neutral element? Explain your answer. a. the number of neutrons in the neutral element b. the number of electrons in the neutral element c. the name of the element

The early alchemists used to do an experiment in which water was boiled for several days in a sealed glass container. Eventually, some solid residue would appear in the bottom of the flask, which was interpreted to mean that some of the water in the flask had been converted into "earth." When Lavoisier repeated this experiment, he found that the water weighed the same before and after heating and the mass of the flask plus the solid residue equaled the original mass of the flask. Were the alchemists correct? Explain what happened. (This experiment is described in the article by A. F. Scott in Scientific American, January \(1984 .\)

Explain the fundamental steps of the scientific method. The scientific method is a dynamic process. What does this mean?

Which of the following statements is(are) true? For the false statements, correct them. a. This ion has more electrons than protons in the nucleus. b. The isotope of \(X\) contains 38 protons. c. The isotope of \(X\) contains 41 neutrons. d. The identity of \(\mathrm{X}\) is strontium, \(\mathrm{Sr}\).
