How many protons neutrons and electrons are there in 131i -?
Answer: Iodine has 53 protons and 53 electrons (because it has no charge the number of protons equals the number of electrons). Iodine-131 has 131 protons and neutrons. Iodine-131 has 131 minus 53 protons = 78 neutrons.
How many protons and neutrons are in an atom 131i iodine-131?
A less stable form of iodine also has 53 protons (this is what makes it behave chemically as iodine) but four extra neutrons, for a total atomic weight of 131 (53 protons and 78 neutrons).
What is the number of protons and the number of neutrons in 131i?
Because its nucleus has the “correct” number of neutrons, it is stable and is not radioactive. A less stable form of iodine also has 53 protons (this is what makes it behave chemically as iodine) but four extra neutrons, for a total atomic weight of 131 (53 protons and 78 neutrons).
How many protons does iodine 127 have?
53 protons
SolutionThe atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 − 53 = 74).
How many neutrons are in iodine 131?
78 neutrons

What is the difference between 35Cl and 37cl they are?
An atom of chlorine-35 contains 18 neutrons (17 protons + 18 neutrons = 35 particles in the nucleus) while an atom of chlorine-37 contains 20 neutrons (17 protons + 20 neutrons = 37 particles in the nucleus). Adding or removing a neutron from an atom’s nucleus creates isotopes of a particular element.
How many protons does 238u have?
Natural Decay Series of Uranium-238 Uranium has an atomic number of 92 which means there are 92 protons and 92 electrons in the atomic structure. U-238 has 146 neutrons in the nucleus, but the number of neutrons can vary from 141 to 146.
How many electrons does calcium have?
20 electrons
In order to write the Calcium electron configuration we first need to know the number of electrons for the Ca atom (there are 20 electrons).
How many protons and neutrons are in an atom 131i Iodine-131?
How many neutrons does iodine 127 have?
SolutionThe atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 − 53 = 74).
How many protons does calcium have?
20Calcium / Atomic number
If we could weigh individual atoms of calcium we would find some variation in their mass; this must be due to variations in the number of neutrons in their nucleus as all must have the same number of protons – 20. Atoms which have the same atomic number but different mass numbers are isotopes.
How many protons does iodine 132 have?
Iodine atoms normally have fifty-three protons and seventy-four neutrons giving an atomic weight of 127. But some iodine atoms have seventy-eight neutrons making a total weight of 131 e31I or iodine-131). Others may have seventy-nine neutrons making a total weight of 132 e32! or iodine-132).
What is the difference between iodine 127 and iodine-131?
Iodine found in the natural environment is called iodine 127. On the other hand, iodine 131 is rarely found in the natural world, but exists in large amounts in nuclear reactors. Iodine 131 is radioactive and changes to a substance called xenon.

How many neutrons does CL 35 have?
18 neutrons
An atom of chlorine-35 contains 18 neutrons (17 protons + 18 neutrons = 35 particles in the nucleus) while an atom of chlorine-37 contains 20 neutrons (17 protons + 20 neutrons = 37 particles in the nucleus). Adding or removing a neutron from an atom’s nucleus creates isotopes of a particular element.
How many protons and how many neutrons are in 238u?
How many protons neutrons and electrons in that order are in the 238u 5 ion?
Write the symbol for this isotope. The atomic number of uranium (see periodic table) is 92, and the mass number of the isotope is given as 238. Therefore, it has 92 protons, 92 electrons, and 238 — 92 : 146 neutrons.
How do you find the electrons?
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
What is the number of protons and electrons in iodine 131?
The atomic number of iodine 131 is 53 so it has 53 protons and 53 electrons. Because iodine 131 has an atomic mass of 131 then it will have 78 neutrons. 131 – 53 = 78
What is the ionization energy of calcium in EV?
First Ionization Energy of Calcium is 6.1132 eV. Ionization energy, also called ionization potential, is the energy necessary to remove an electron from the neutral atom. where X is any atom or molecule capable of being ionized, X + is that atom or molecule with an electron removed (positive ion), and e − is the removed electron.
