On what does mass depend on?

Answer 1

For a given radioactive element, the critical mass required to initiate a self-sustaining chain reaction depends mainly on three aspects

1) the purity of the element (elimination of unwanted isotopes or other elements)

2) the shape of the mass

3) the quantity of the mass

These last two are practically the same, because both directly determine the neutron flux.

the catalyst

the polarity

Answer 2

Mass depends on the amount of matter contained in an object. It is a measure of the quantity of particles (atoms and molecules) that make up an object. The more particles an object has, the greater its mass.

Answer 3

mass depends on the amount of matter in an object.

Answer 4

(Almost) only on the total of proton AND neutron number of the atom (isotpoe) concerned. This number is called the mass number. (Remember: m=n+p)

Answer 5

Mass depends on the amount of matter.
