Antimony
Antimony (symbol Sb) has three isotopes: 121Sb, 123Sb, and 125Sb. The 121 isotope has 70 neutrons, and the 123 isotope has 72 neutrons. The 125 isotope isn't stable and will decay, but it has 74 neutrons.
The element with 72 electrons is Hafnium (Hf). Hafnium has an atomic weight of 72 and is a period 6, group 4 transition metal. It is the first element after the Lanthanides. Hafnium has 72 electrons in 6 shells with 2 electrons in the outer shell.
32 protons, 32 electrons. Ge-72 isotope has 40 neutrons
* Number of Electrons: 72 * Number of Neutrons:106 * Number of Protons: 72 * Number of Electrons: 72 * Number of Neutrons: 106 * Number of Protons: 72
Refer to the Periodic Table. Iodine has atomic Number of 53. This tells us that there are 53 protons in the nucleus. I-127 is the Atomic Mass. The figure is the total of all the protons and neutrons in the nucleus of the atom. So the total number of neutrons will be 127 - 53 = 74 neutrons.
Protones = 51 Electrones = 49 Neutrones = 70 or 72
Atoms have 3 parts: Protons, Neutrons, and Electrons. In a neutral atom, the atomic #= number of protons, and everything else is equal to it. For example: Hafnium, Atomic#=72= 72 protons, 72 neutrons, 72 electrons= neutral atom.

The atomic number of zinc is 30. So there are 30 protons, 30 electrons in zinc.
Refer to the Periodic Table. Iodine has atomic Number of 53. This tells us that there are 53 protons in the nucleus. I-127 is the Atomic Mass. The figure is the total of all the protons and neutrons in the nucleus of the atom. So the total number of neutrons will be 127 - 53 = 74 neutrons.
The atomic number of an atom tells you how many protons are present in the nucleus. So there are 50 in the element. By the way, an element with 50 protons and 70 neutrons (120-50) is a stable form of Tin.
Hafnium has 72 electrons and protons; the number of neutrons is different for each isotope and depend on atomic mass of the isotope.
The isotope Germanium -72 has 32 proton, 40 neutrons and 32 electrons. Two other stable isotopes are Ge-70 (38 neutrons) and Ge-74 (42 neutrons) both with the same numbers of protons and electrons as Ge-72 There is also a low percentage stable isotope Ge-73
