im pretty sure it is 2. i was hoping to find the answer to this online, but it turns out I'll be answering it
This is the electron configuration for Zr: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d2
and there are 2 electrons in the outermost energy level of 5.
BTW, if you do not know about electron configs, they are based on the Periodic Table an are in the format of nle where n is the energy level (1,2,3,4...); l is the sublevel (s,p,d,f in that order) and e is the number of electrons. S sublevel can fit 2, P 8, D 18, and F 32.
^^^ Number of electrons per sublevel is calculated using the formula of twice the sublevel squared.
Good luck!

What is zirconium atomic mass?
Zirconium, a transition element with an atomic number of 40, has several isotopes, and each has a different mass number. Zr-88 (mass number 88), Zr-89 (mass number 89), Zr-90 (mass number 90), Zr-91 (mass number 91), Zr-92 (mass number 92), Zr-93 (mass number 93), Zr-94 (mass number 94) and Zr-96 (mass number 96).
F the transition metal zirconium (Zr) has the electron configuration of Kr 5s2 4d2 what is the electron configuration of Zr3 plus?
The electron configuration of zirconium (Zr) is Kr 5s² 4d². When zirconium loses three electrons to form Zr³⁺, it typically loses the two 5s electrons first, followed by one 4d electron. Therefore, the electron configuration for Zr³⁺ is Kr 4d¹.
How many unpaired electrons in Zr?
None. Zinc fills up its 3d sublevel with 10 electrons, all pairs. So, there are no remaining unpaired electrons
How many electrons are in each shell around the nucleus of a Zr?
In a Zirconium (Zr) atom, the electron configuration is [Kr] 5s2 4d2. This means there are 2 electrons in the outermost shell (5s) and 2 electrons in the second outermost shell (4d), for a total of 4 electrons in the shells around the nucleus.

What is the element 54 protons 54 neutrons and 78 electrons?
I think you meant "54 protons, 54 electrons, and 78 neutrons," because I don't think it's possible for any element to have such a high proton-electron different, especially when that element is the noble gas Xenon. Anyways, if you did make a typo, the element you're thinking of should be Xenon-134
What is the electrons per shell for the element zirconium?
Zirconium (Zr) is on the 5th row of the periodic table, in the 2nd column of the transitional metals, so its first 4 electron shells are full (like Kr), and the 5s orbital is full with 2, and the 4d shell has the last 2. The configuration is: 1s22s22p63s23p64s23d104p65s24d2. (That adds up to 40, Zr's atomic number!)
