Ba
there are 234 ion electrons in 1N3 atom. This was discovered by Charles Babbage a late 18th century physist in BritainTrillions. Essentially one for each proton.
Xenon has 54 protons or 54 electrons. Its electronic configuration is Kr] 5s2 4d10 5p6 or 2, 8, 18, 18, 8
The atomic number of xenon is 54. It has 54 electrons and its electronic configuration is 2, 8, 18, 18, 8 or [Kr] 5s2 4d10 5p6
For an atom of xenon, the number of particles in the nucleus would be the sum of the protons and neutrons. Xenon has 54 protons and usually around 78 neutrons, so the total number of particles in the nucleus would be around 132.
One normal water molecule has 2 protons plus the quantity of 8 protons and 8 neutrons. That it is a total of 18 nucleons. As all nucleons have 3 valence quarks, then there are 54 quarks in 1 normal water molecule.
There are 53 protons and 53 electrons in an iodine atom.
Iodide ion or I- ion
The net charge of an iodine ion with 53 protons and 54 electrons is -1, because it has one more electron than proton. The number of neutrons does not affect the charge of the ion.
The atomic number of iodine, or I, is 53. Thus, neutral iodine would have 53 protons and 53 electrons. However, since we're talking about I-, we need to add an additional electron to this number, making it 54. Finally, the specific isotope of iodine in question, 131I, has 131 - 53 = 78 neutrons.
As an iodine atom has 53 electrons, an iodide ion has 54 electrons.
The ion with 52 protons, 76 neutrons, and 54 electrons is the ion of element tellurium (Te) with a charge of +2. The number of protons determines the element, the number of neutrons can vary in isotopes, and the number of electrons determines the charge of the ion.
An ion with 54 electrons and a -1 charge has one more proton than the number of electrons to balance the charge. Therefore, it has 54 + 1 = 55 protons. This means the ion is an anion of an element with an atomic number of 55, which is cesium (Cs).
Barium (Ba) has an atomic number of 56, which means it has 56 electrons in a neutral atom. The "2" you mentioned likely refers to the charge on the barium ion (Ba2+), which means it has lost two electrons, resulting in 54 electrons in the Ba2+ ion.
Iodine (symbol I) has atomic number 53, which means that it has 53 protons in the nucleus (by definition). Since an atom is neutral overall, and the charge on an electron is equal and opposite to that of a proton, the atom has 53 electrons.Being a group VII element (also known as a halogen), it gains one electron to fill its outer shell when it forms an ion (the I- ion). This gives it a total of 54 electrons.
I-125 contains 73 neutrons. To calculate the number of protons, electrons, and neutrons in an uncharged isotope, follow these rules: Protons = atomic number Electrons = protons = atomic number Neutrons = atomic mass - protons Iodine is number 53 on the periodic table, so its atomic number is 53. It has 53 protons and 53 electrons. This particular isotope of iodine is I-125. So, it has 125-53=72 neutrons.
The element xenon (Xe) has 54 protons and 54 electrons.
Iodine has 53 protons. Iodine 127 has 74 neutrons. With a negative charge, it would have an extra electron, meaning it would have 54 electrons.
