You are given both the energy level, n = 4, and the subshell, l = 3 on which the electrons reside.
The subshell is given to you by the angular momentum quantum number, l which can take value that ranges from 0 to n − 1
l = 0 → the s-subshell
l = 1 → the p-subshell
l = 2 → the d-subshell
l = 3 → the f-subshell
<u>For n = 4 and l = 3, ml can be -3, -2, -1, 0, +2, +2, and +3. </u>
<u>Each of these can have 2 electrons (+1/2 and -1/2 spin) for a total of 14 electrons.</u>
Answer:
7.5 pounds per square-inch
At sea level, one square-inch of any surface has about 15 pounds of air sitting on top of it. At 18,000 feet, that same square inch has only 7.5 pounds per square-inch (psi) exerted on it.
Answer:
storage solution , deionized water, stabilizes
Explanation:
A pH meter is a scientific device or instrument that is used to measure the pH of a given aqueous solution thereby determining the nature of the solution whether it is acidic or basic or neutral.
While using the pH meter or taking the measurement using the pH meter --
- it should be kept in a storage solution for effective working.
- Before using the device, it is rinsed with a deionized water and pat dry.
- Record the measurements when the pH meter stabilizes.
For this case, Only 1 isotope would be present, i.e. the principal element with mass M=13 and then one isotope at mass M+2. <span>We are assuming that the principal element is the one that is the lowest mass - by definition, an isotope is one where there are additional neutrons - hence the mass increases, but the proton count is the same.
