Each proton serves as a positive charge and each electron serves as a negative charge. The two charges neutralize each other on a 1:1 ratio. In your question, you have 12 protons to 13 electrons. That means there's a net -1 charge because there is one more electron than protons.

c Example 1 represents a liquid and Example 2 represents a solid.
Explanation:
Example 1: Young children dancing slowly around one another
The young children dancing slowly around one another can be pictured as the flow of liquid. In liquids, the molecules are held about weakly and they slide on top of each other. They are held by weak attractive forces. This is clear picture of a liquid.
Example 2: Newborn babies sitting in their given spots in a crib
This is clear example of a solid. In a solid the molecules are held about a fixed spot. The attractive forces in liquids is very great and the molecules therein do not move about randomly.
