The radius of an atomic nucleus is generally expressed in units of
Answers
Answer:
The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment. ... Protons and neutrons are bound together to form a nucleus by the nuclear force.
Answer:
Explanation:
The usual unit used to express atomic radii is either the nanometer (1 billionth of a meter, or 10^-9 meters) or the angstrom (1 tenth of a billionth of a meter, or 10^-10 meters). This is the unit used for atomic radii, which corresponds to the radius of the outer orbital of electrons that surrounds the nucleus, not for the radius of the nucleus itself. The nucleus, consisting of a number of protons and neutrons, is at the (positively charged) core of any atom. Nuclear radii are typically expressed in units of femtometers (1 quadrillionth of a meter, or 10^-15 meters).
