Why atoms trade electrons to find stability
In short: Discover the mechanics of ionic bonding by exploring how lithium and fluorine interact. This video clarifies how atoms achieve stability through electron transfer and electrostatic attraction.
Ionic bonding occurs when atoms transfer electrons to form oppositely charged ions, which then attract one another. For example, lithium (a Group 1 metal) has one valence electron, while fluorine (a halogen) has seven. When lithium transfers its electron to fluorine, they become Li+ and F- ions, respectively.
A common misconception is that atoms must have eight electrons in a shell to be stable. However, stability is reached whenever a shell is full. A Li+ ion is stable because its first shell holds only two electrons, mirroring the electronic structure of a helium atom.
