How many neutrons does an atom of radium have?

Answer 1

The number of neutrons in the nucleus in any atom varies, however, the average is easy to find. The atomic number is the number of both protons and electrons. The Atomic Mass is the number of AMUs (atomic mass units) in the atom. 1 amu is the same as the mass of 1 proton or 1 neutron. the mass of the electrons is negligible. Because of this, subtract the atomic number from the atomic mass and you should have the average number of neutrons.

Answer 2

The atomic mass is 226, and the number of protons is 88. Subtract the atomic mass from the number of protons.

226-88= 138 neutrons

Answer 3

The atomic number of uranium is 92. So there are 92 electrons and 92 protons (irrespective of the isotope under consideration).

Answer 4

The isotope radium-232 has 144 neutrons.

Answer 5

An atom of radium typically has 138 neutrons.

Answer 6

90
