Look at the table, which lists some common ions. Find the name of an ion in the first column, its charge (positive or negative) in the second column, and its symbol or formula in the third column. How can you tell which ions had lost electrons?

• The ions with a negative charge have lost electrons.
• The ions with a positive charge have lost electrons.
• The ions with a neutral charge have lost electrons.
• You cannot tell the charge of an ion from this chart.
