Who is James Chadwick. Becuase the neutron has no charge it made it difficult to detect as it doesn't react to negative or positive charges.
The difference between atomic mass, mass number, and atomic number.
What is atomic mass is the sum of the mass of all subatomic particles

What is the density of a object with a mass of 8184 grams and a volume of 3 cm3?
What is 2938 g/cm3?
With most substances solubility increases with temperature why is this the case?
(Answer does not have to be in the form of a question)
The movement of the particles increase with temperature and that causes more collisions between atoms which results in things breaking down faster.
