Does Removing an electron from an atom release energy?

Answer 1

No. Instead, the atom will become positively charged. Since electrons have a negative charge, and elements usually have an equal amount of protons and electrons, when an electron is lost, there are more protons left than electrons, thus making it positively charged.

Answer 2

This depends on whether the energy level is a greater or lower potential. This can be thought of as imagining standing in the middle of a hill on earth. The higher u go up the hill, the more gravitational energy needed, so energy is required. But u could jump/slide down the hill, thus releasing energy (u'd feel it as kinetic).

When an electron goes down a level, a photon is released, if an electron goes up a level, this is because energy has been absorbed.

This is more of a classical answer.

Agree, however, it may be easier to grasp if thought of as such: as an electron receives energy, at a specific energy level that electron will jump up to a higher, but very specific orbit around it's nucleus. The electron loses energy both in the process of that orbital jump, and in it's orbital momentum. As it loses energy, once again at a very specific energy level, it will drop back down in it's orbital radius in specific orbits dependent upon it's energy level at that moment, and in the process of falling back to a smaller orbital radius it emits a photon each time it's orbital radius drops to the next lower level. So, simply ... the electron absorbs x quantity of energy at time t, jumps to a higher orbit dependent on the quantity of energy absorbed, loses it's energy kinetically in the process of radial momentum and the energy expended in the jump itself, and as it falls to a lower orbital position emits a photon, falls to the next lower orbital position and emits a photon, and on and on depending on how many orbits it originally jumped based on the original quantity of energy absorbed. Keeping in mind that this process of dropping down an orbit or a few may be interrupted if the electron receives a new input of energy, causing it to jump back up some number of orbits, again dependent on the quantity of energy received, lose kinetic energy as described earlier, and again begin the process of dropping back down in it's orbital radius and emitting a photon again in each drop to a lower orbit. And in nearly all cases an electron in an energetic space will do this jump/drop/emit photon/jump/drop/emit photon dance a zillion times a second. (OK, maybe not a zillion, but a whole bunch of times each second). Everything is dependent on it's energy level at time t.

Answer 3

No, it is NOT true. When an electron is excited is has gained energy. It releases energy when it returns to the ground state.

Answer 4

nope, never.
