I am struggling with ionic bonds. If we look at the carbonate compound, we see it consists of 1 carbon atom and 3 oxygen atoms. Yet, it has 2 more electrons than protons and that is what makes it a negative ionic compound. But why does it have TWO more electrons than protons if there are THREE oxygen atoms, contributing ONE electron each? Shouldn't it have THREE more electrons than protons?

Create a class named Exponent. Its main() method accepts an integer value from a user at the keyboard, and in turn passes the value to a method that squares the number (multiplies it by itself) and to a method that cubes the number (multiplies it by itself twice). The main() method displays the results. Create the two methods that respectively square and cube an integer that is passed to them, returning the calculated value. Save the application as Exponent.java
. Write an application that displays all even numbers from 2 to 100 inclusive, and that starts a new line after every multiple of 20 (20, 40, 60, and 80). Save the file as EvenNums.java.
