What is the trend in sizes of the ions n3−, o 2−, f− and why does the trend exist? 1. n 3− > o 2− > f −; the effective nuclear charge is smallest at n3− and the largest at f −. 2. n 3− > o 2− > f −; for an isoelelectronic series, the ionic size decreases as the p + e− ratio decreases. 3. impossible to tell, since ionic radii for different elements cannot be compared; ions can only be compared to the neutral atom. 4. f − > o 2− > n 3−; in an isoelelectronic se-?

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water
