An atom of an element is made up of protons, neutrons, and electrons. Protons have a charge of +1+1​. Electrons have a charge of −1−1​. Neutrons have no charge. The charge of an atom is the sum of the charges of its protons and electrons. Oxygen has eight protons and eight electrons so its overall charge is \displaystyle +8+\left(-8\right)=0+8+(−8)=0​. When an atom’s charges do not add up to zero, it is called an ion. The charge contributed by protons and electrons for some atoms and ions are shown in the table below.   What is the overall charge of argon​? What is the overall charge of lithium​?   thank you !!!!!!!!!!!!! i'm a 7th grader in math class and need help
