Neutrons = 207 - 82 = 125

82. Lead is an element with symbol Pb and atomic number 82. The atomic number relates to the amount of electrons of the element

217 centimeters = 7.12 feet.

The element with atomic mass number 207 is lead (Pb). Lead is a heavy metal that is commonly used in batteries, construction materials, and ammunition.

If you look on the periodic table, you will find that the atomic number for lead is 82. This means that there will always be 82 protons. Next, assuming that there are not ions, the number of elections is also 82. Finally, you can see that the mass number of Pb is 207. 207-82=125 so there are 125 neutrons if you are referring to the most common isotope.

207 is a composite number. Its factors are: 1, 3, 9, 23, 69, and 207

207 is not a prime number because it gets divided by 3.

The number 207 is "two hundred seven."

It is 207/3 = 69.

The atomic number of lead (Pb) is 82, which represents the number of protons. To find the total number of neutrons, subtract the atomic number from the mass number. For lead-207 (207Pb), the mass number is 207. Therefore, the total number of neutrons in an atom of 207 82 Pb is 207 - 82 = 125 neutrons.

207 is an integer and so there is no sensible way of writing it as a mixed number.
