Metallic bonding DEFINITION
In metallic substances, atoms achieve noble gas electron configuration by releasing their valance electrons, thus forming positive metal ions and free electrons
Ionic bonding DEFINTION
Form a combination of metallic elements with non-metallic elements.
Bonding in the ionic lattice
Due to strong electrostatic attraction between positive and negative ions.
Any given positive ion is attracted to its surrounding negative ion
Covalent bonding DEFINITION
Occurs whenever a nonmetal element bonds with another nonmetal element
Shared valance electrons
Intramolecular forces
Strong covalent bonds
Only form between atoms within molecules
Intermolecular
Weak forces
Occur between neighbouring molecules
Nanotechnology
is the manipulation of matter on an atomic, molecular, and supramolecular scale.
Nanoscience and nanotechnology
the study and application of extremely small things and can be used across all Science fields
