= 1
= 1
Explanation:
Argon atom has atomic number 18. Then, it has 18 protons and 18 electrons.
To determine the quantum numbers you must do the electron configuration.
Aufbau's principle is a mnemonic rule to remember the rank of the orbitals in increasing order of energy.
The rank of energy is:
1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d < 5p < 6s < 4f < 5d < 6p < 7s < 5f < 6d < 7d
You must fill the orbitals in order until you have 18 electrons:
- 1s² 2s² 2p⁶ 3s² 3p⁶ : 2 + 2 + 6 + 2 + 6 = 18 electrons.
The last electron is in the 3p orbital.
The quantum numbers associated with the 3p orbitals are:
- n = 3
- the fourth quantum number, the spin can be +1/2 or -1/2
Thus, the six possibilities for the last six electrons are:
- (3, 1, -1 +1/2)
- (3, 1, -1, -1/2)
- (3, 1, 0, +1/2)
- (3, 1, 0, -1/2)
- (3, 1, 1, +1/2)
- (3, 1, 1, -1/2)
Hence, the correct choice is:
- n = 3

Answer:
#include<cstdlib>
#include<bits/stdc++.h>
#include<time.h>
using namespace std;
class Colors{
string colors[7];
public:
void setElement(int,string);
void printAllColors();
void printRandomColor();
};
void Colors::setElement(int index,string color){
colors[index] = color;
}
void Colors::printAllColors(){
cout << "Printing all the colors:\n";
for(int i=0;i<7;i++){
cout << colors[i] <<"\t";
}
}
void Colors::printRandomColor(){
srand (time(NULL));
int index = rand() % 7;
cout<< "\n\nThe random picked color:";
cout << colors[index] << endl;
}
int main(){
Colors color;
color.setElement(0,"red");
color.setElement(1,"orange");
color.setElement(2,"yellow");
color.setElement(3,"green");
color.setElement(4,"blue");
color.setElement(5,"indigo");
color.setElement(6,"violet");
color.printAllColors();
color.printRandomColor();
}
to get the random color we are using srand and rand function. we are using time as seed to srand() function,because every time the time is changed. And based on that we are using rand() function and doing mod with 7 with the random number to get the index between 0 to 6, as ut array size is 7(0 to 6).
In the setElement(int index,string color) method we are inserting the value of colors in the colors array based on index.
In the printAllColors() function we are printing all the colors in the array.
In the printRandomColor() er are printing any random color based on rand() function.
and in main() we are initializing the string array with colors and calling the functions.
