To create a molecular model, a student will use blue spheres to represent nitrogen (N) and white spheres to represent hydrogen (H). Which option correctly describes a model of ammonia, NH3?(1 point)
three blue spheres and three white spheres
three blue spheres and three white spheres
one blue sphere and three white spheres
one blue sphere and three white spheres
one blue sphere and one white sphere
one blue sphere and one white sphere
three blue spheres and one white sphere
one blue sphere and three white spheres
The correct option to create a model of ammonia, NH3, would be:
one blue sphere and three white spheres
To correctly create a molecular model of ammonia (NH3), you will need to represent the nitrogen and hydrogen atoms accurately. The molecular formula for ammonia, NH3, consists of one nitrogen atom (N) and three hydrogen atoms (H).
To represent the nitrogen atom (N), you should use blue spheres, and for the hydrogen atoms (H), you should use white spheres.
Now, let's analyze the options:
Option 1: "Three blue spheres and three white spheres."
This option fits the correct molecular formula since it consists of three blue spheres (representing nitrogen) and three white spheres (representing hydrogen). So, this option correctly represents the model of ammonia, NH3.
Option 2: "One blue sphere and three white spheres."
This option does not match the correct molecular formula of ammonia, NH3. It consists of one blue sphere (representing nitrogen) and three white spheres (representing hydrogen), which is incorrect.
Option 3: "One blue sphere and one white sphere."
This option does not match the correct molecular formula of ammonia, NH3. It consists of one blue sphere (representing nitrogen) and one white sphere (representing hydrogen), which is incorrect.
Option 4: "Three blue spheres and one white sphere."
This option does not match the correct molecular formula of ammonia, NH3. It consists of three blue spheres (representing nitrogen) and one white sphere (representing hydrogen), which is incorrect.
Therefore, the correct option is:
Option 1: "Three blue spheres and three white spheres."
