__ Outer Electrons __

1 The Inert/Noble Gases all have 8 outer electrons and are stable so they don’t react.

2 Elements form bonds to get 8 outer electrons like the nearest Inert Gas.

3 Elements in the same groups have the same number of outer electrons.

4 Elements in the same groups have similar chemical properties.

5 Atoms either lose loosely held electrons or gain them.

6. The attractive force from the rearrangement of electrons between atoms can form chemical bonds. End..........................................................................................
