Antimony
This electron would have 51 protons and 51 electrons. The number of electrons in an atom is equal to the number of protons, as atoms are electrically neutral.
Element X with 72 protons will have 72 electrons in a neutral state. The number of protons in an element is equal to the number of electrons in that element's neutral atom.
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.
* 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.
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.
Protones = 51 Electrones = 49 Neutrones = 70 or 72
Element X with 72 protons will have 72 electrons in a neutral state. The number of protons in an element is equal to the number of electrons in that element's neutral atom.
the atomic number of hafnium is 72, protons? 72, neutrons? 106, electrons? 72
All elements on the periodic table are neutral because they have the same number of electrons as protons. Protons carry a positive charge, while electrons carry a negative charge, and having an equal number of each results in a neutral charge overall.
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.
The atomic number of zinc is 30. So there are 30 protons, 30 electrons in zinc.
* 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.
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.
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.
A neutral germanium atom has 32 electrons and typically 41 neutrons.
Hafnium has 72 electrons and protons; the number of neutrons is different for each isotope and depend on atomic mass of the isotope.
