The farther an electron is from the nucleus of an atom, the more energy it has.
The energy change that occurs when an atom gains electrons is called the
Yes, when an effective nuclear charge increases it does pull the electrons closer to the nucleus. An electron is a negatively charged part of an atom.
The energy change that occurs when an electron is added to a gaseous atom is called the electron affinitybecause it measures the attraction, or affinity, of the atom for the added electron.The ionization energy measures the energy changes associated with removing electrons from an atom to form positively charged ions.
Electrons are located in energy levels within the electron cloud.
The energy of electrons is expressed in eV (electron volts).

When electrons change energy levels they usually become more stable. Sometimes when electrons change energy levels they become unstable though.
Electrons in the outermost energy shell (valence shell) have the most energy.
Yes, an electron's movement is related to its amount of energy. As a matter of fact, everything's movement, not just an electron's, is related to the amount of energy that that thing has. As the energy of an object increases, either its translational, rotational, vibrational, or some combination of the three, motion increases.

The amount of energy required to remove an electron increases from left to right. This means that the atoms are able to hold on to their valence electrons more and more tightly. Thus, it gets harder to remove an electron as the atomic number increases. Going down a group, the element doesn't change much. However, the size of the atom increases greatly, and because of this, so does the distance between the nucleus and the valence electrons. That decreases the magnitude of the force of attraction between the nucleus and the outermost electrons. Thus, IE decreases going down a group from top to bottom. http://forums.studentdoctor.net/showpost.php?p=2720248&postcount=3
No. Electrons will orbit around an atom only at specific energies (which change depending on the atom's atomic number and atomic mass). If you try to use a photon to change the energy of an electron and move it to another orbit path (or "energy level"), and the photon has the wrong energy in it, the electron won't change its orbit.
The outermost electrons are called VALENCE electrons.
The energy of electrons is expressed in eV (electron volts).
when you go down a group you get more shells and in those shell are electrons the further away the electrons are from the protons and neutrons the less energy you need to pull of the electrons.
