### What element has 82 protons and 124 neutrons?

A The element with 82 protons (atomic number of 82) is lead: Pb. B For the first isotope, A = 82 protons + 124 neutrons = 206. Similarly, A = 82 + 125 = 207 and A = 82 + 126 = 208 for the second and third isotopes, respectively. The symbols for these isotopes are

### How many neutrons are in an ion with a charge of +2?

Since it has a charge of +2 , this ion must contain 80 electrons. Because neutrons and protons both have a mass of about 1 amu, the difference between the mass number (210) and the atomic number (82) is equal to the number of neutrons in the nucleus of the atom. The ion therefore contains 128 neutrons.

How many protons neutrons and electrons are in 210pb2+?

Determine the number of protons, neutrons, and electrons in a 210Pb2+ion. Answer The atomic number of lead is 82, which means this ion contains 82 protons. Since it has a charge of +2 , this ion must contain 80 electrons.
