Chapter 3: Problem 45

For each of the questions, four choices have been provided. Select the correct alternative. An atom of an element has 9 electrons with \(1=0\) value, 18 electrons with \(\mathrm{l}=1\) value and 10 electrons with \(1=2\) value. Calculate the atomic number of the element. (a) 37 (b) 41 (c) 38 (d) 39

Short Answer

Expert verified
Answer: The atomic number of the element is 37.

Step by step solution

01

Determine the number of electrons for each l value

We are given the following information: - 9 electrons with l=0 - 18 electrons with l=1 - 10 electrons with l=2
02

Calculate the total number of electrons

Now that we know how many electrons correspond to each l value, we can calculate the atomic number by summing up these electron counts: Total number of electrons = Electrons with l=0 + electrons with l=1 + electrons with l=2 Total number of electrons = 9 + 18 + 10 = 37
03

Select the correct alternative

As we have calculated the total number of electrons (atomic number) to be 37, the correct alternative is (a). Therefore, the atomic number of the element is 37.
