What is reactivity? Reactivity refers to how likely or vigorously an atom is to react with other substances (atoms, molecules, etc). This is usually determined by how easily electrons can be removed (we call it ionization energy!) and how badly they want to take other atom''s electrons (we call it electronegativity). Elements with high electronegativity will be very reactive,
