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... :)

What is the second principle energy level?
The second principle energy level is the energy level that comes after the first principle energy level. The second energy level is farther from the atomic nucleus and contains the 2s and 2p sublevels.
The first element with an electron in the second energy level?
Lithium
What element contains two electrons in its fifth energy level?
Strontium (Sr)
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.
A neutral atom with an atomic number of 15 will have electrons in its outermost energy level?
The element is phosphorus and it contains 5 valence electrons.
How many element are located in the second energy level if an atom has 7 element?
5 atoms are located in the second energy level if the first energy level has 7.
The second energy level contains how many electrons when it is full?
The second energy level contains eight valance electrons when it's full.
What element contains two electrons in its third energy level?
mg
What element contains 1 electron in its fifth energy level?
Rubidium
What is the second principle energy level?
The second principle energy level is the energy level that comes after the first principle energy level. The second energy level is farther from the atomic nucleus and contains the 2s and 2p sublevels.
The first element with an electron in the second energy level?
Lithium
How many electrons does phosphorus have in its outermost principal energy level?
The total number of electrons in Phosphorus (P) is 15 (its atomic number). The first energy level contains 2, the second energy level contains 8, and the third energy level contains 5.
What element contains two electrons in its fifth energy level?
Strontium (Sr)
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.
A neutral atom with an atomic number of 15 will have electrons in its outermost energy level?
The element is phosphorus and it contains 5 valence electrons.
Which element have 10 electrons and 10 neutrons?
Neon is the element with 10 electrons. Neon has 2 electrons in the K shell (or first energy level), and 8 electrons in the L shell (the second energy level).
What is the number of the lowest energy level that contains an f sublevel?
The 4th energy level is the lowest that contains and f sub-level
