Neutrons are amotic mass subtract protons which would be 127 rounded up minus 53 giving you 74 !!

Most atomic of iodine has 74 neutrons. The atomic weight of iodine (126.9) represents the combined mass of protons, neutrons, and electrons in the atom. Since the atomic number (53) represents the number of protons in the nucleus, subtracting the atomic number from the atomic weight gives the number of neutrons.

How many protons electrons and neutrons respectively does iodine have?
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.
What is the Atomic weight of iodine-126?
126 atomic mass units. 53 protons 73 neutrons
Atomic weight is equal to the?
Atomic weight/ mass = number of protons + number of neutrons
How do you get the atomic number and weight?
No. of protons=No. of electrons = Atomic number. No. of protons + No. of neutrons = Atomic mass.
How is the atomic weight of an element found?
you add the number of protons (the atomic number) to the number of neutrons

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.
The number of neutrons in an atom can be found by subtracting the atomic number from the?
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.
What is the Atomic weight of iodine-126?
126 atomic mass units. 53 protons 73 neutrons
What is the number of neutrons in an atomic number?
Subtract the atomic number from the atomic weight.
An atom of atomic number 53 and mass number 127 has how many neutrons?
because neutrons and electrons weight nearly the same, and electrons have such little mass that they are virtually insignifigant, the amount of neutrons can be found by subtracting the protons from the total weight. total weight-protons=neutrons(roughly) so in this case, the cobalt (atomic # 27) has 28 neutrons
Is atomic number the number of protons and neutrons?
No, the atomic number is the same number of protons and electrons. To find the neutrons, you subtract the atomic weight by the atomic number. Make sure to round the atomic weight as well.
Atomic weight is equal to the?
Atomic weight/ mass = number of protons + number of neutrons
Is the atomic number of an atom the number of neutrons?
Subtract the atomic number from the atomic weight.
How can you calculate the number of neutrons N in an atom?
equal to number of protons
Is the atomic weight the same as the atomic number?
No, the atomic number is the number of protons that an atom contains. Atomic weight is the number of protons and neutrons.
How man neutrons dose uranium have?
Each isotope of an element has a specific number of neutrons (number of neutrons = atomic weight - atomic number).
Is the atomic weight of an element is equal to the number of protons minus the number of neutrons?
Atomic weight of an element is the number of protons plus neutrons in the nucleus, atomic number is the number of protons only.
