How many protons and neutrons does radium have?
88
When radium-226 decays to form radon-222 the radium nucleus emits a?
When Radium-226 decays to form Radon-222, the Radium nucleus emits an alpha particle. The atomic number goes down by 2, and the mass number goes down by 4, matching the atomic number and mass number of the alpha particle.

The most stable isotope of radium - 226Ra - has the atomic mass 226,025 409 8 (25).
How many proton and neutron are in radium?
What is the decay process does radium 226 undergo including the nuclear changes that occur?
Radium-226--------------------Radon-222 + alpha
After undergoing alpha decay an atom of radium -226 becomes?
Radium 226 decays by alpha emission to Radon 222. A helium nucleus is emitted by alpha emission which makes the mass reduce by 4 and its atomic number by 2.
What is the most reactive alkaline earth metal?
Radium (Ra), atomic number 88, is the most reactive alkaline earth metal. It has the most energy levels of all the alkaline earth metals therefore it's electrons are more easily taken away.
When radium -226 decays to form radon -222 the radium nucleus emits?
When radium-226 decays to form radon-222, the radium nucleus emits a alpha particle.
