Nickel is a metal element. Mass number of it is 58.
Nickel has 28 protons. An atom of nickel-61 contains 33 neutrons.
30 neutrons in Ni-58 isotope.
The number of neutrons depends on the atom. In general, mass number = atomic number + number of neutrons.
An atom with an atomic number of 23 has 23 protons. The only thing that determines the atomic number of an element is the number or protons in its nucleus. The proton count is the sole determinant as to the elemental identity of every atom. An atom with an atomic mass of 51 and an atomic number of 23 has 28 neutrons, as atomic weight - atomic number = number of neutrons. The atom described here is an atom of nickel, and it's nickel-51, which is a radioactive isotope of nickel that we've created in the physics lab.
The atomic weight minus the number of protons = the atom's neutrons.
Nickel has 28 protons and electrons; the number of neutrons is different for each isotope.
Mass number = Atomic number (or number of protons) + Number of neutrons
The number of neutrons in the nucleus of an atom is always the difference between the mass number of the atom and the atomic number of the atom. Therefore, in this instance, there are (155 - 63) or 92 neutrons in the atom.
How many neutrons would it have if it had 11 neutrons? 11.
6 neutrons
112 neutrons
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
