fourth period
The third period is similar to the second, except the 3s and 3p sublevels are being filled. Because the 3d sublevel does not fill until after the 4s sublevel, the fourth period contains 18 elements, due to the 10 additional electrons that can be accommodated by the 3d orbitals.
Instability of an atoms nucleus can result from an excess of either neutrons or protons . So neutrons and protons .

Answer: five cause </h3>
The number of energy levels of zirconium is 5, and I know this because it is located in family five. Families are the rows across on the periodic table. The family number is always equal to the number of energy levels.Zirconium: properties of free atoms. Zirconium atoms have 40 electrons and the shell structure is 2.8.
