Electron Configuration.  In atomic physics and quantum chemistry, electron configuration is the arrangement of electrons of an atom. electrons.

What causes reactivity of elements All atoms want to have a completely full valence shell (normally 8 electrons). For the moment we will only concentrate.

Day 4 – Reactivity & Ions Sci 10 Chemistry. Noble gases are the most popular group  A full valence shell contains happy electrons that want to stay where.
