Two types of ions
Cat-ions and An-ions
Cat-ions are positive because they ____electrons
Loose
An-ions are negative because they ______ electrons
Gain
What ion is mostly positive. And are mostly metals (they loose) and have low Electronegativity
Cat-ions
What ions are mostly negative and are non metals with high Electronegativity
An-ions

VSEPR
Valence shell electron pair repulsion
VSEPR theory states ????
Electron pairs orient themselves in order to mini mixed repulsive forces
Lone pairs repel more than bounded pairs
True
2 electron regions , bounded to 2 atoms , bound angle 180*
Linear (geometry)
