Zirconium element has 40 protons.It is a d block element.
The atomic number is the number of protons in the nucleus which, for a neutral atom, would be 32.
argon is element 18, and so has 18 protons. argon 40 has a mass of 40, so subtracting 18 protons gives you 22. Thus, there are 22 neutrons
K always has 19 protons, because that is what defines it as an element.40, the atomic mass is the sum of protons and neutrons. So if you subtract the number of protons from the atomic mass, you get the number of neutrons.40-19=21 neutrons
Manganese, the 25th element, has 25 protons.

Protons are protons, no matter what element they are in.

Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
Several can. Perhaps you meant to ask which has 20 protons, in which case the answer is calcium. (Calcium is also one of the elements that can have 20 neutrons, but it's not the only one.)
what element contains 16 protons? what element contains 10 protons?
Manganese, the 25th element, has 25 protons.
All atoms of the same element have the same number of protons. Atoms of different elements have different numbers of protons. The number of protons determines the element.
In the natural form, it is Zr with 40 protons, 51 neutrons and 40 electrons. . But some isotopes have an atomic mass of 91 too.
The element mercury has 80 protons.
