Imagine that a coffee filter is falling through the air after being released from a specific height. The filter accelerates for a time and rotates a bit so that the bottom of the filter is facing down, but then reaches a terminal velocity. Now, it is continuing to fall at a constant speed without tipping or rotating. At this moment, is the coffee cup in equilibrium?

When electrons are added to the outermost shell of a carbon atom, it forms--an anion that has a larger anion that has a smaller cation that has a larger cation that has a smaller radius.
