A stable atom with 90 neutrons could potentially have a maximum of 90 protons, as the number of protons would have to be equal to or less than the number of neutrons for the atom to be stable.
Most stable nuclei have a roughly equal number of protons and neutrons, which helps to balance the forces that hold the nucleus together. This balance of protons and neutrons helps minimize the nucleus's potential energy, making it more stable.
Having an equal number of anything does not make an atom stable.
Often, but not always, atoms with an equal number of protons and neutrons in the nucleus are stable and not radioactive.
No. In fact the largest stable nucleus of any atom in it's non isotope form is Lead at 82 protons
There are 41 protons in Niobium. The atomic number is the same as the number of protons.

On the contrary, deuterium is stable.
Protons are within the nucleus
A stable one.

the element is stable.
Often, but not always, atoms with an equal number of protons and neutrons in the nucleus are stable and not radioactive.
Bismuth-209 is stable because it has an odd number of protons and an even number of neutrons, making it less susceptible to radioactive decay. Additionally, bismuth-209 is the heaviest stable isotope of bismuth, which further contributes to its stability.

The majority of stable atoms have slightly more neutrons than protons, but the numbers are similar. The biggest exception is hydrogen, which has a stable isotope having one proton and no neutrons. Many of the lighter elements have stable isotopes in which the number of protons and the number of neutrons is the same. But as the elements get heavier, we increasingly find that stable isotopes have more neutrons than protons. This is an understandable pattern. Protons, all of which have a positive charge, repel each other. It is the neutrons which act as a kind of nuclear glue, holding the nucleus together against the repulsive force that protons exert on each other. As the nucleus gets bigger, more neutrons are needed to hold it together.
