<em>Since the 3s if now full we'll move to the 3p where we'll place the remaining five electrons. Therefore the Chlorine electron configuration will be 1s22s22p63s23p5. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.</em>
In Alpha decay two neutrons and protons are lost, so the mass decreases by four and the atomic number decreases by two.
Therefore the correct answer is B: Ra-224.
