Definition
Proper noun:
- Ernest Rutherford: A British physicist, born in New Zealand, renowned for discovering the atomic nucleus and proposing a nuclear model of the atom (1871-1937).
- Daniel Rutherford: A British chemist known for isolating the element nitrogen (1749-1819).
Noun:
- A unit of radioactivity: A unit of radioactive source strength equal to one million disintegrations per second.
Usage Examples
Proper noun (Ernest Rutherford):
- Ernest Rutherford is often called the father of nuclear physics.
- Rutherford's gold foil experiment was crucial in understanding atomic structure.
Proper noun (Daniel Rutherford):
- Daniel Rutherford discovered nitrogen in 1772.
- The chemist Rutherford was a student of Joseph Black.
Noun (Unit):
- The sample's activity was measured at 2.5 rutherfords.
- Older literature might cite radioactivity in rutherfords instead of becquerels.
Advanced Usage
"Rutherford model": Refers specifically to the planetary model of the atom proposed by Ernest Rutherford.
- The Rutherford model depicted electrons orbiting a dense, central nucleus.
"Rutherford scattering": Refers to the phenomenon observed in Ernest Rutherford's experiment where alpha particles are deflected by a atomic nucleus.
