Which isotope of which element? The answer depends entirely on those details.
In one atom of cobalt ion, the number of neutrons can vary based on the isotope. The most common isotope of cobalt is cobalt-59, which has 33 neutrons.
A hydrogen-1 isotope contain one proton, one electron, and 0 neutrons; this is the only naturally occcurring isotope with no neutrons in its structure.
there are 8 neutrons (assuming the oxygen is the naturally occurring one).
By striking it with neutrons.
Normal Hydrogen has one proton. The isotope of Hydrogen called Deuterium has one proton and one neutron. The Isotope of hydrogen called Tritium has one proton and two neutrons. All isotopes of hydrogen have one electron.
10 neutrons in Ne-20 isotope
In one atom of cobalt ion, the number of neutrons can vary based on the isotope. The most common isotope of cobalt is cobalt-59, which has 33 neutrons.
it depends on the element and isotope
A hydrogen-1 isotope contain one proton, one electron, and 0 neutrons; this is the only naturally occcurring isotope with no neutrons in its structure.
No neutrons; H-1 has only one proton and one electron.
there are 8 neutrons (assuming the oxygen is the naturally occurring one).
There are 77 Neutrons in the nucleus of one atom of Xenon
The numer of neutrons depends on the isotope, which, as you've noted, Xenon has several of. Pick one.

Normal Hydrogen has one proton. The isotope of Hydrogen called Deuterium has one proton and one neutron. The Isotope of hydrogen called Tritium has one proton and two neutrons. All isotopes of hydrogen have one electron.
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
