What happens to an atom if the electrons in the outer shell are altered?

Question

Quizplus · Accepted Answer

The properties of the atom will change if the electrons in the outer shell are altered. This is because the outermost electrons are responsible for the atom's chemical behavior and reactivity. If they are altered, the atom's ability to form chemical bonds and interact with other atoms will be affected, changing its properties. However, this does not necessarily mean the atom will become a different element or disintegrate, and it does not necessarily mean it will become radioactive.
