What is the difference between an electron donor and electron acceptor?
Donor atoms are atoms that donate electrons and have an extra pair of electrons in their orbital. Acceptor atoms are atoms that accept electrons and have a empty orbital to accommodate the extra electrons.
Why it is difficult to remove an electron from halogens?
In their outer electron shell, halogens have 7 valence electrons, one less than the number needed for a full shell. Therefore, it is much, much easier for the halogen to gain an electron in bonding than for it to lose 7 - the ionization energy (energy required to remove an electron from an atom) is quite high.

How are atoms in an X-ray tube anode ionized?
The atoms in the anode of an X-ray tube are ionized by an incoming beam of high energy electrons. Those electrons streamed off the cathode and were accelerated by the high voltage across the tube's elements. The high energy electron beam slams into the specially alloyed anode and ionizes the atoms there. The ionized atoms have their outer electrons torn out to very high energy levels, and when they de-ionize, they do so by emitting a high energy photon - an X-ray. The anode gets hot as heck, too.
Conductivity in a metal results from the metal atoms having?
highly mobile electrons in the valence shell
The ability of atoms to combine with other atoms is determined by?
The number of electrons of both atoms and its valence number.
A high-energy electron from the necleus?
The electrons with the highest energy are an atom's valence electrons. These are the electrons in the outermost energy level, or valence shell, which is the part of an atom that participates in a chemical reaction.

Is atoms with high ionization energy allow their electrons to be easily taken?
This is false. The ionization energy is the amount of energy that is required to remove the electron. Therefore, if it requires more energy, it is harder to remove the electron.
What do all elements group 1 have in common in terms of electrons?
Group A1 of the Periodic Table (Hydrogen, Lithium, Sodium . . . ) is an Alkali Metal and only has one valance electron. If the element were to lose that electron, it forms an ion. Each element violently reacts when combined with water.

What happens when an electron moves from a low energy state to a high energy state?
when an electron moves from low energy state to high energy state , it gains energy.
Where do electrons lost by metal atoms during the formation of ions come from?
When chemical bonds form, thermal energy supplies some of the energy needed to remove electrons from metal atoms. Also, energy is released as the electron associates with another atom. This energy contributes to the removal of electrons from metal atoms too; both processes happen simultaneously (as the electron moves away from the metal, it moves closer to the other atom. Because of this, there is a lower activation for the process than there otherwise would be). In some cases, the electron is not passed to another atom. This can occur when a high energy photon is absorbed, which ejects the electron from the metal.
Is the potato the high energy electron?
yes, the potato would be the hgh energy electron
Does chlorine have a high electron affinity or a low ionization energy?
It has High electron affinity.
