I think it will be zinc. The electron configuration of zinc is:
1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10
Add up the electrons. 2+2+6+2+6+2+10 = 30 electrons in all, which is the element zinc.
As you can see frorm the above electron configuration, all the electrons for the third energy level are filled: 3s2 is filled; 3p6 is fully filled; 3d10 is fully filled.
I really hope this helps and doesn't confuse you... :)

Which element has 2 energy levels with 5 electrons in my order energy level?
This element is likely phosphorus (P), which has 15 electrons in total. With 5 electrons in the second energy level, phosphorus has 2 energy levels: the first energy level with 2 electrons and the second energy level with 5 electrons.
What is the second principle energy level?
The second principle energy level is designated as the n=2 energy level in an atom. Electrons in this energy level have higher energy than those in the first energy level. The second energy level can hold up to 8 electrons.
What is an element whose atoms contain 4 electrons in the second energy level?
Carbon. Carbon is in the second period, so it has electrons in its second energy level, and it is in the fourth group in the second energy level, so it has 4 electrons.
