Answer:
4d orbital.
Explanation:
Hello!
In this case, since zirconium's atomic number is 40, we fill in the electron configuration up to 40 as shown below:
![1s^2,2s^2,2p^6, 3s^2,3p^6,4s^2,3d^{10},4p^6,5s^2,4d^2](https://tex.z-dn.net/?f=1s%5E2%2C2s%5E2%2C2p%5E6%2C%203s%5E2%2C3p%5E6%2C4s%5E2%2C3d%5E%7B10%7D%2C4p%5E6%2C5s%5E2%2C4d%5E2)
Thus, the orbital 4d is partially filled.
Best regards!

Showing respect
Explanation:
Being first at everything is immature, playing on a cell phone is being off task, and using a fire blanket to keep warm in class shows that you are doing nothing to contribute to the lab.
Max Planck was studying the emission of light by
hot objects. He believed that the hot objects did not emit energy continuously,
as would be expected if it were in the form of waves. Instead he suggested that
the object emits the energy in small, specific amounts called quanta. A quantum
is the minimum quantity of energy that can be lost or gained by an atom. He
proposed the following relationship between a quantum of energy and the
frequency of the radiation: E = hn.
E represents the energy in joules of a quantum of radiation, n<span> is the frequency of the radiation emitted, and
h is a constant known as Planck’s constant. Albert Einstein introduced the idea
that electromagnetic radiation has a dual wave-particle nature. Example: white
light exhibits many wavelike particles, it can also be thought of as a stream
of particles. Each particle of light carries a quantum of energy. He called
these particles photons. A photon is a particle of electromagnetic radiation
having zero rest mass and carrying a quantum of energy.</span>
The stable form of Nitrogen is N-14 and N-15.
- Nearly all proteins contain nitrogen, which is crucial for biochemical processes as well as industrial processes.
- Due to its capacity to form a triple bond with both itself and other elements, nitrogen forms strong bonds. As a result, nitrogen compounds contain a lot of energy. Little was known about nitrogen before one hundred years ago.
- More than 99 percent of all nitrogen found on Earth is found in the most abundant form of nitrogen, nitrogen-14. non-radioactive and stable, it is a substance.
- The most widely used form of nitrogen, 14, is used in biochemicals, biomedical research, food preservation, and agricultural practices.
- The second stable state of nitrogen is nitrogen-15. It is frequently employed in medical preservation and research.
