Answer:
As any molecular or ionic compound, 0 net charge, as a hypothetical diatomic cation, 2+
Explanation:
The question states that this is a compound, and any molecular or ionic compound would have a net charge of 0.
However, such a compound doesn't exist. Francium generally exists in nature having a 1+ charge in its cation form. Combining two francium ions would result in a species which is simply a diatomic ion but not a compound.
Explanation:
The kinetic energy of translation
m= mass v= linear velocity
The kinetic energy of rotation
I= MOI of the thin walled sphere =kmR^2
where ω= v/R= angular velocity
Then
=1/k
solid sphere: k=0.4; E1/E2 =1/0.4 = 2.5;
hollow sphere: k=2/3; E1/E2 = 1.5
