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 slotted link is pinned at o, and as a result of rotation it drives the peg p along the horizontal guide. compute the magnitude of the velocity and acceleration of p along the horizontal guide. compute the magnitudes of the velocity and acceleration of p as a function of θ if θ=(3t) rad, where t is measured in seconds.
