How many protons neutrons and electrons does iodine 128 have?
128 Protons, 128 Neutrons, 75 Electrons.
Does iodine-131 and iodine 125 have the same atomic number?
As all three atoms are isotopes, therefore, atomic number is the same for each of them. The atomic number of iodine is 53 and the alphabetical symbol of iodine is I.
How many neutrons are in iodine 125?
72 neutrons
Iodine 125 (I-125) is the isotope of iodine whose nucleus consists of 53 protons and 72 neutrons.
How many protons neutrons and electrons does iodine 127 have?
The 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 neutrons and electrons does iodine 131 have?
I is iodine. Iodine is element number 53. 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.
How many protons neutrons and electrons are in iodine?
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. 5.
How many neutrons are there in iodine?
Iodine has 74 neutrons, 53 protons and 53 electrons, giving it an atomic mass of 126.9. While solid at room temperature with a density of 4.93 grams per cubic centimeter, iodine melts at 236.7 degrees Fahrenheit and boils at 364 degrees Fahrenheit.
What is the number of protons in iodine?
These have some properties in common with iodine while there are also certain “trends” or patterns in the variation of other properties across this group of elements.) Each iodine atom consists of 53 protons, 53 electrons plus a quantity of neutrons whose exact number* depends on the particular isotope of iodine (see below).
How many electrons are in iodine?
What is Iodine Iodine is a chemical element with atomic number 53 which means there are 53 protons and 53 electrons in the atomic structure.
How do you determine protons electrons and neutrons?
That number is equal to the number of protons. The number of protons is equal to the number of electrons, unless there’s an ion superscript listed after the element. To find the number of neutrons, subtract the element’s atomic number from its atomic mass (the number listed underneath the element).
