Simplify the following text for a Grade 8 native English-speaking person.
Original: Metallic bonding is mostly non-polar , because even in alloys there is little difference among the electronegativities of the atoms participating in the bonding interaction ( and in pure elemental metals , none at all ) . Thus metallic bonding is an extremely delocalized communal form of covalent bonding .
Simplified: Metallic bonding is the bonding between atoms within metals .
