Difference between null & "" & empty

Just a general question. What is the difference between an imaginary index 0 of a list when it is either:

[0] null
or
[0]
or
[0] Empty List

null is nothing, 0 is a value zero and empty list is a instantiated list of nothing.

subscript:
I apparently forgot to describe the blank incident (""), that is a instantiated string of length zero
