This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
how many energy levels are filled in a krypton atom They have four levels. You always put 2 in the first. 8 in the second. 18 in the third. And I believe you are able to put 36 in the fourth level, but correct me if I'm wrong about the fourth level.

Calcium and krypton have 4 electron shells.Sulfur has 3 electron shells.Iodine has 5 electron shells.
Krypton has 8 valence electrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Plutonium has seven electron shells.
The noble gases, which are helium, neon, argon, krypton, xenon, and radon, have their outermost electron shells full.
Magnesium has 3 electron shells. The electron configuration is : 2,8,1
The correct number of electron clouds or shells sodium has is 3.
Phosphorus in is 3rd period. So it has 3 electron shells.
