Atoms with a low ionization energy readily give up their valence electrons.
true or false

True

Explanation:

The weak electrostatic force between the electrons and nucleus isn't strong enough to cause repulsion and they are loosely held by the nucleus. Generally all ions with low ionization energy loses electrons faster and readily compared to ions with high ionization energy. Most metallic ions of group I, ii, iii lose electrons faster than group 16, 17 elements.

chemical energy --> gravitational potential energy --> kinetic energy --> elastic potential energy --> gravitational potential energy

explanation:

when emma starts the hike, the chemical energy stored in her body is used to climb up the mountain, and so she gains gravitational potential energy (because at the end, she will be at a higher height h above the ground). then she goes bungee jumping: as she falls, this gravitational potential energy is converted into kinetic energy (because her speed increases as she falls down), until the point when the rope stretches, and she stops moving. at that moment, all the kinetic energy is converted into elastic potential energy due to the stretching of the rope. then, this energy is released because the rope returns to its natural length, and emma gains a small increase in altitude , so she gains some gravitational potential energy.
