When vegetables are prepared on a cutting On the other hand, electrons that have only one electron in their valence shells (Group 1 elements) or elements that are just one electron short of having a complete shell (Group 17) are the most reactive. The elementary electric charge of the electron is a negative one, making it a subatomic particle. The bond is formed when an atom, typically a metal, loses an electron orelectrons, and becomes a positive ion, or cation. For example, atoms with complete valence shells, the noble gases, are the least chemically reactive. Calcium (Ca) reacts with chlorine (Cl) to form the ionic compound calcium chloride. A magnesium (Mg) atom gives one electron to two atoms of another element, and takes on a 2+ charge. This gives it one less negative charge than positive charges and an overall charge of 1+. .
