An MRI scan is obtained by using radio frequency waves (similiar to FM radio waves) to energize Hydrogen atoms in fat and water. When you add energy to the Hydrogen atoms you can create a signal that can be then turned into an image.
The mass number of an atom is obtained by totaling the number of protons and neutrons.
Dalton's mental image of an atom was a hard sphere that was the same throughout.
The mass of an atom is obtained dividing the atomic weight of an isotope by the Avogadro number.
The mass number of an atom is obtained by totaling the number of protons and neutrons.

an isotope of the element helium is obtained.
No, after the alpha decay of polonium lead isotopes were obtained.
Metals are mixed together in the molten state, to form alloys. For example, nichrome is obtained by mixing nickel and chromium.
