The mass number for iodine is 131, which is the sum of the protons and neutrons. Iodine has 53 protons and 53 electrons, if neutral. To find how many neutrons iodine has subtract 53, the number of protons from the mass number of 131. This shows that iodine has 78 neutrons.

How many protons and neutrons and electrons does the ion Na 1?
The ion Na+ has 11 protons, 12 neutrons, and 10 electrons. This is because sodium has an atomic number of 11, meaning it naturally has 11 protons and 11 electrons, but as an ion with a +1 charge, it has lost 1 electron.
How many protons neutrons and electrons will positive two ion of calcium have?
A positive two ion of calcium will have 20 protons, 18 neutrons, and 18 electrons. The number of protons and neutrons in a calcium ion remains the same as in a neutral calcium atom (calcium has 20 protons and about 20 neutrons in its nucleus), but it loses two electrons to become positively charged.
If An ion has 8 protons 9 neutrons and 10 electrons the symbol for the ion is?
The symbol for the ion with 8 protons, 9 neutrons, and 10 electrons is ^17O.

How many protons neutrons and electrons in Ce3 plus?
The ion Ce(3+) of the isotope Ce-140 has 58 protons, 82 neutrons and 55 electrons.
What ion has 52 protons 76 neutrons and 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.
How many protons and electrons are in 64 29 Cu2 plus ion?
29 protons and 27electrons are present in Cu2+ ion.
If a nitride ion has a charge of -3 the ion must have protons electrons and neutrons?
A nitride ion (N³⁻) has a charge of -3, meaning it has three more electrons than protons. Nitrogen has 7 protons in its nucleus, so the nitride ion has 7 protons and 10 electrons. The number of neutrons can vary depending on the isotope, but the most common isotope of nitrogen has 7 neutrons, giving a total of 7 protons, 10 electrons, and 7 neutrons in a nitride ion.
How man protons and neutrons does aluminum ion Al 3?
13 protons and 14 neutrons. The fact that its an ion doesn't change that ... only the number of electrons.
How many electron proton and neutron does a mg2 plus ion have?
Mg has 12 protons, 12 electrons and 12 neutrons.Mg^2+ ion has 12 protons, 10 electrons and 12 neutrons. The number of protons and neutrons remains the same, but since the ion now has a 2+ charge, it has lost 2 electrons.
How many electrons protons and neutrons respectively are in the iron III ion 56FE3 plus?
The iron III ion, 56Fe3+, has 26 protons, 30 neutrons, and 23 electrons. This is derived by considering the atomic number of iron (26) along with the charge of +3, which means it has lost 3 electrons.
