1) electronegativity - ability to attract e, become negatively charged
increase left to right, and bottom to top (F = most electronegative)
1) strong to weak forces - ionic-covalent-metallic-van der waals-hydrogen
1) materials classification - metals
ceramics
, polymers
composites
semiconductors
Biomaterials
1) materials science - search for basic knowledge:
internal structures
properties
processing of materials
1) materials engineering - use of fundamental and applied knowledge:
of materials that can be "converted" into products necessary or desired by society
1) materials structure - structure depends on arrangement of internal components (sub, micro, macro)
1) photon energy - electromagnetic radiation
1) quantum numbers - (n) principle QN = # of atomic shells in Bohr model
(l) subsidiary QN = s,p,d,f--> # of subs hell in main energy level
(ml) = magnetic QN = spatial orientation
(ms) = e spin QN = 2 allowed spin directions
1) net force - Fn= Fa+Fr
(magnitude of force = function of interatomic distance)
1) calculator mode - degrees
1) CP1. grams/atom - g/mol divided by atoms/mol
