Answer:
Explanation:
Given that,
Width of a one dimensional potential box,
The energy of a particle in one dimensional box is given by :
h = Planck's constant
m = the mass of the proton
For minimum kinetic energy, n = 1
So, the minimum kinetic energy of the neutron is . Hence, this is the required solution.
Answer:
Cesium has smallest ionization energy.
Explanation:
Ionization energy is the energy that an atom at ground state must be absorb to release an electron to form a cation. for eg.
H ⇒
The unit of ionization energy is .
The ionization energy is minimum for cesium & maximum for fluorine.
Ionization energy depends upon the radius of atom. cesium has smallest radius so it has low Ionization energy.
Therefore the cesium has smallest ionization energy.
