Finals Studying Flashcards
What is an ion? How are ions formed?
An ion is an electrically charged atom that is formed when it loses or gains valence electrons.
Define ionization energy and describe how the trend can help us make predictions about chemical reactivity.
Ionization energy is the amount of energy that is required to remove an electron from an atom. This measures how hard it is to remove valence electron from an atom of that element.
