Magnesium has 2 valence electrons, and oxygen has 6 valence electrons. which type of bonding is likely to occur between a magnesium atom and an oxygen atom?

1. ionic—magnesium will give 2 electrons to oxygen, and both will become ions.

2. ionic—oxygen will give 2 electrons to magnesium, and both will become ions.

3. metallic—oxygen and magnesium atoms will be surrounded by a pool of electrons.

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.
