Two electronics technicians are looking at the representations of a silver atom and a copper atom in the figure above. Technicia
n A says that silver and copper are both good conductors because their atoms have single electrons in their outermost orbits. Technician B says that silver is a better conductor than copper because the silver atom's free electron is farther from its nucleus than the copper atom's free electron is from its nucleus. Which of the following statements is correct?
A. Neither of the two technicians is correct.
B. Both Technician A and Technician B are correct.
C. Only Technician B is correct.
D. Only Technician A is correct.
A. Neither of the two technicians is correct.

Answer:
I am writing a C++ and JAVA program.
import java.util.Scanner; //for using input output functions
public class LabProgram { // class name
public static void main(String[] args) {//start of main function body
Scanner input = new Scanner(System.in);
// creates input instance of Scanner type
String str; // declares String type variable str for a string value
int num; // declares integer type variable num to hold an integer value
str = input.next(); //scans and reads input string from user
num = input.nextInt(); //scans and reads input integer from user
//while loop continues to execute until user enters quit 0
while(str!="quit" && num!=0) {
/* prints the following message, for example if value of num = 2 and value of str = apples then the following print statement prints Eating 2 apples a day keeps the doctor away. */
System.out.println("\nEating " + num +" " + str + " a day keeps the doctor away.");
//takes string and integer as input again and keep taking input until user //enters quit 0
str = input.next();
num = input.nextInt(); } } }
Explanation:
The program is well explained in the comments mentioned with each statement of the program. The program simply prompts user to enter a string and an integer. The while loop keeps executing until user enters quit 0. The program keeps taking input string and integer from user and prints the message System.out.println("\nEating " + num +" " + str + " a day keeps the doctor away."); The loop breaks when the use enters quit 0. The screenshot of the program along with its output is attached.
