3. use models suppose a black ball represents a hydrogen atom and a yellow ball represents a nitrogen atom. describe how you would make a model of an ammonia molecule, nh₃.

Answer

Brief Explanations:

The chemical formula NH₃ indicates that an ammonia molecule has 1 nitrogen atom and 3 hydrogen atoms. According to the given model - representation (black for hydrogen, yellow for nitrogen), we need to use 1 yellow ball for the nitrogen atom and 3 black balls for the hydrogen atoms. Then, connect the 3 black balls (hydrogen atoms) to the 1 yellow ball (nitrogen atom) to form the ammonia - molecule model.

Answer:

Use 1 yellow ball (nitrogen atom) and 3 black balls (hydrogen atoms), and connect the 3 black balls to the 1 yellow ball.
