It's in the outermost shell of the electron.
Electrons with less energy are most likely (if not always...) located on the most inner orbital :)
The Valence electrons, i.e. those in the outer shell of a compound are most likely to be involved in bonding. This is because they are further away from the nucleus of their atom, so experience less attractive force towards it. They are also shielded from this attraction by any electrons between them and the nucleus. Therefore, they require less energy to remove.
this is because u use less energy. LESS ENERGY = LESS TO PAY
Not necessarily.More energy is transferred through a wire when the product of(number of electrons carried) times (voltage between the ends of the wire)is greater.
Not all electrons are the same age, since there are a variety of processes by which subatomic particles can change into other particles (by reason either of decay, or high energy collision with other particles). However in general, electrons formed not long after the Big Bang which was a bit less than fourteen billion years ago.
Ionization energy is the energy required to remove an electron from an atom or ion. Low ionization energy indicates that it takes less energy to remove an electron from the atom. The alkali metals are in Group I on the Periodic Table. This indicates that their atoms have only one electron (out of a possible eight) in their outermost energy level. Therefore it takes less energy to remove the single outermost electron. Moving across a period on the Periodic Table, ionization energies increase because there are more and more electrons in the outermost energy level, requiring more energy to remove an electron.

Valence Electrons are the electrons that are located furthest away from the atom itself in the outermost electron shell. They are located on the last energy level also known as the valence level.
When the light "activates" the electrons, it kicks them up into higher orbitals where they have more energy. That extra energy is utilized to power the photosynthesis reaction.

Phosphorus has a higher energy level so it pulls harder on its electrons.
Metals lose electrons more easily than the non-metals because they require less ionization energy compared with the non-metals. The metals require less ionization energy to lose the electrons than though gain the electrons unlike the non-metals.
Close to the nucleus. At that position, they have less potential energy. It is as if an object is lower in a gravitational field (closer to Earth); therefore, these energy levels are also called "lower energy levels", by analogy.
An atom that has fewer than 8 valence electrons is more reactive, or more likely to form bonds, than an atom with 8 valence electron. Atoms bond by gaining, losing, or sharing electrons in order to have a filled outermost energy level with 8 valence electrons.
In any atom, the electrons that have the most energy are the outermost, because the greater energy an electron has, the greater its velocity, and when anything has greater velocity, it has a greater momentum and a greater orbit. Think of a planet orbiting the sun. If the planet were faster, it would start to have greater inertia and be affected by the sun's gravity less, causing the orbital radius to increase. The case is similar with electrons. Since energy gives electrons a higher velocity, they start to orbit farther away from the nucleus. Therefore, the electrons in the outermost energy level or orbital always have the greatest energy and are less stable because of it.
There is less repulsion by electrons.
The number of valence electrons is the number of electrons in the outer energy ring of an atom. The most electrons the first energy level of any atom can hold is two. The rest is 8. If the outer energy level is full, the atom will be less reactive because it cannot add any more electrons to it's current outermost energy level. If it only needs one or two more electrons to fill it's last energy level or if it only has one or two in it's last energy level, it will be more reactive, because it only needs to gain a few or lose a few to be full.
In general, electrons farther from the nucleus will have more energy than electrons closer in. These "outer" electrons are said to be in higher Fermi energy levels, and they have more kinetic energy than the electrons in lower orbitals. Consider that electrons give up energy to "fall into" closer orbitals, and they will, in general, have less energy than the outer electrons. A consequence of the idea that there is less energy binding outer electrons to that nucleus is that it takes less energy to remove that outer electron from an atom. These are the so called ionization energies of the atom's electrons. And when the electron is in a higher orbital, it has a lower ionization energy. It can be removed more easily. As we attempt to remove more electrons from that atom, it takes progressively more and more energy as we move inward removing electrons.
