Silver has 5 energy levels. 😄

The range of the levels is between 0 to n-1. 3 minus 1 equals to 2, so we have 0, 1, 2 as sub levels. They are the same number of sub-levels.

Three sublevels: px, py, pz
Yes, there are times that ice can be as hard as steel in sub zero levels.
Sub energy pretty much explains itself: It is below energy level
Silver (Ag) has an atomic number of 47, and its electron configuration is [Kr] 4d¹⁰ 5s¹. The sub-shell being filled by silver is the 4d sub-shell, which is fully filled with 10 electrons. Additionally, the single electron in the 5s sub-shell contributes to its chemical properties.
No -- silver is an element. It's smallest possible component is an atom of silver, which (obviously) can not be sub-atomic.
sub levels
There are one 3s orbital, three 3p orbitals, and five 3d sublevels.
its the subcomponents that give a energy to prove your self better.
