The atom that has a charge of -1 is atom 3.
To get the net ionic charge, we will use the formula as shown:
Net ionic charge = Number of protons present in an ion + Number of electrons present in an ion.For atom 1;
Net ionic charge = 9 - 9
Net ionic charge = 0
For atom 2;
Net ionic charge = 9 - 8
Net ionic charge = + 1
For atom 3;
Net ionic charge = 9 - 10
Net ionic charge = -1
For atom 4;
Net ionic charge = 9 - 9
Net ionic charge = 0
From the calculation above, the atom that has a charge of -1 is atom 3.

Explanation:
To compare the average amount of time that canadians and americans spend commuting, a researcher collects a sample of canadians and americans. The canadians spend an average of hours a week commuting, with a standard deviation hours. The mean and standard deviation for the sample of americans is hours and hours, respectively. The standard error of the difference of sample means is:.
The standard error of the difference of sample means is 0.444
From the complete question, we have the following parameters
Canadians
Sample size = 50Mean = 4.6Standard deviation = 2.9Americans
Sample size = 60Mean = 5.2Standard deviation = 1.3The standard error of a sample is the quotient of the standard deviation and the square root of the sample size.
This is represented as:
[tex]SE = \frac{\sigma}{\sqrt n}[/tex]
The standard error of the Canadian sample is:
[tex]SE_1 = \frac{2.9}{\sqrt{50}}[/tex]
So, we have:
[tex]SE_1 = 0.41[/tex]
The standard error of the American sample is:
[tex]SE_2 = \frac{1.3}{\sqrt{60}}[/tex]
So, we have:
[tex]SE_2 = 0.17[/tex]
The standard error of the difference of sample means is then calculated as:
[tex]SE= \sqrt{SE_1^2 + SE_2^2}[/tex]
This gives
[tex]SE= \sqrt{0.41^2 + 0.17^2}[/tex]
[tex]SE= \sqrt{0.197}[/tex]
Take square roots
[tex]SE= 0.444[/tex]
Hence, the standard error of the difference of sample means is 0.444

Methane is the principal carbon substance in natural gas. Natural gas is tasteless, colorless, and odorless, so gas companies add mercaptan to give it an unpleasant stench that can be used to detect leaks in natural gas pipes.
Natural gas is given the chemical mercaptan in order to make leaks simpler to find. The most crucial fact about mercaptan is that it smells bad. It has been compared by some to the stench of rotting eggs. Its odor is quite intolerable in concentrated form.
