There are 41 protons in Niobium. The atomic number is the same as the number of protons.
Nickel has 28 protons. An atom of nickel-61 contains 33 neutrons.
A typical atom of iodine contains 74 neutrons.
Nucleus (and it consists of protons and neutrons).
Niobium only seems to have one valence electron. Why it doesn't have two like the rest of the transition metals is beyond me.
45 neutrons
An osmium atom has 76 protons and 76 electrons, as the number of protons equals the number of electrons in a neutral atom. A niobium atom has 41 protons and 41 electrons. These numbers correspond to their respective atomic numbers on the periodic table.
A stable atom of Zinc (Zn) typically has 34 neutrons.
The atomic weight minus the number of protons = the atom's neutrons.
A typical atom of iodine contains 74 neutrons.
A stable magnesium atom has 12, 13 or 14 neutrons. The atom with 12 neutrons is the most common one.
