Asample of sodium-22 (z= 11) decays to neon-22 (z 10). the alf-life of this sodium isotope is 2.5 years. the masses of the sodium-22 and neon- 22 atoms are 21.994434 u and 21.991383 u, respectively. the initial mass of the sodium-22 sample is 5 mg. [2 points] what is the radius of the sodium-22 nucleus?

is the radius of the sodium-22 nucleus.

Explanation:

Where:

= Constant for all nuclei

r = Radius of the nucleus

A = Number of nucleons  or atomic mass

Radius of the sodium-22 nucleus

Atomic mass of Na-22= 21.994434 u

A = 21.994434

is the radius of the sodium-22 nucleus.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
