Density and atoms Quiz

Density determines the...

• Sink or float of an object

• Difference of mass and volume

• The solubility of a hidden figure

• The capacity of an object

Which is more dense? How is this so?

• Option a because the volume is lower.

• option a because the mass is higher

• Option b because the volume is higher

• Option b because the mass is lower

• 12 g/cm³

• 12 grams

• 12 kg/cm³

The theory where atomic compounds are structured

• Bohr Model theory

• Interpretive Diagram theory

• Chemical Compound theory

• Dalton's atomic theory

What caused scientist to change from one model to another?

• Addition was least common in Bohr models and many weren't interested.

• Scientist found a new method to tranquilize dose of atomic structure.

• The colors of atoms have different types of energy emmitted.

• Scientist felt that the energy of Dalton's models weren't better than the frequency of Bohr models.

What was the main purpose of the Dalton Model?

• To spread a new theory of atomic structure.

• To persuade scientist to try his idea.

• To increase luminosity of atoms.

• To say that atoms have compounds.

What was significant about Rutherford's model of an atom?

• He invented the nucleus of an atom in a model.

• he invented the nucleus of an atom.

• It named the particles in the air as atoms.

• He invented the parts of an atom.
