Lesson 6 Atoms vs Ions

Atoms
-as written on PT
all atoms are neutral because #p = #e

Ions
charged particles due to #p does not = #e

 
Octet Rule: Every element wants a noble gas configuration (complete outer shell). They will lose or gain valence electrons to do so.

Metals
*have 1 or 2 valence electrons
*Lose electrons to form POSITIVE ion (ca+ion)
*lose e- get smaller
*Radius atomic>ionic

Nonmetals
*have 6 or 7 valence electrons
*Gain electrons to form NEGATIVE ion (anion)
*gain e- get bigger 
*Radius atomic<ionic
