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.

What is the symbol for an atom of radium 88 protons and 140 neutrons?
Ra-228
What has 88 protons and 138 neutrons?
The number of protons of an atom is given by its atomic number. Checking the periodic table, we see that the atom with 88 protons is radium. The isotope of radium with 138 neutrons would thus be 226Ra.
How many valence neutrons are in radium?
Radium has one valence electron.
What is the radium-235 atom?
It is an isotope of the element, radium (Ra), with 88 protons, 88 electrons and 147 neutrons (235 - 88 = 147).
How many electrons and neutrons are in radium?
Radium has 88 electrons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass - 88 The most stable and known isotope of radium, 226Ra, has 138 neutrons.
