This is called 'radioactive decay'. Each element exists in the form of atoms with several different sized nuclei, called isotopes. Unstable isotopes (which are thus radioactive) are called radioisotopes.

WebGiven that Aluminum is a group 13 element, it's most stable form would be to achieve pseudo-noble gas configuration, so it would be to lose three electrons, rather than one or two. However, given the context the question, being either losing one or two electrons, I would hypothesize that losing two electrons is more stable. Web20 jan. 2024 · How Ions Are Formed. As we've learned before, atoms like to be stable. They feel most stable when their outer electron shells are full. They become full when they have eight electrons in them.
