In an ionic compound the metal ion always A. donates/gives away valence electrons to become a cation.

B. accepts electrons to become an anion.

C. shares electrons with the electron sea.

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
