Q

Metallic bonding DEFINITION

A

In metallic substances, atoms achieve noble gas electron configuration by releasing their valance electrons, thus forming positive metal ions and free electrons

24
Q

Ionic bonding DEFINTION

A

Form a combination of metallic elements with non-metallic elements.

25
Q

Bonding in the ionic lattice

A

Due to strong electrostatic attraction between positive and negative ions.
Any given positive ion is attracted to its surrounding negative ion

26
Q

Covalent bonding DEFINITION

A

Occurs whenever a nonmetal element bonds with another nonmetal element
Shared valance electrons

27
Q

Intramolecular forces

A

Strong covalent bonds

Only form between atoms within molecules

28
Q

Intermolecular

A

Weak forces

Occur between neighbouring molecules

29
Q

Nanotechnology

A

is the manipulation of matter on an atomic, molecular, and supramolecular scale.

30
Q
