Why do the rows in the periodic table get progressively longer as you move down the table? For example, the first row contains two elements, the second and third rows each contain eight elements, and the fourth and fifth rows each contain eighteen elements. Explain The rows in the periodic table grow progressively longer because you are sorting elements according to their frequency of occurrence in nature. The rows in the periodic table grow progressively longer because you are adding...

Assume we have these two classes. Note that they are in separate packages. If the code works, tell me what it prints. Otherwise, tell me (in your own words) why it doesn’t work. ● In one package: public class MyClass { int x = 5; } ● In another package: public class Main { public static void main(String args) { MyClass obj = new MyClass(); System.out.println(obj.x); } }
