Al (Aluminum) can lose three electrons to empty its valence energy level. Chemistry is the science of matter and the changes it undergoes. hope this helps! :)

What role do valence electrons play in the formation of compound from elements?
Valence electrons are the electrons on the outer most shell of a neutral atom; they are used when forming chemical bonds with other atoms. Because of the octet rule - which is a chemical bonding theory based on the assumption that in the formation of compounds, atoms exhibit a tendency for their valence shells to either be empty or a full 8 electrons (octet) - atoms that do not have an octet need to either get rid of their electrons or gain more electrons. Atoms combine with other atoms in order to stabilize themselves. For example if sodium and chlorine were to combine sodium would need to lose 1 valence electron while chlorine would need to gain 1 valence electron. Na + Cl ------> NaCl FYI NaCl, sodium chloride, is table salt. *NB* All elements react in order to become stable and either get an octet or empty their shell. They are all attempting to be like the noble gases, which are hellium, neon, argon, krypton..etc. FYI noble gases are all stable and have 8 valence electrons.
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.
What happens for an atomic emission of photons to occur?
Electrons fall from higher energy state to lower energy state in atoms. This can be from outer shells to empty spaces in inner shells or from outside the atom to an empty space in a shell.
Some matirals are good counductors because they are able to easily transfer what patticals from one atom to another?
the conductivity of a material depends on the transfer of electrons from valence band to conduction band , when the two atoms come closer their outer energy shells (that are active in transfer of electrons ) get divided into two levels valence band which is full of electrons of lower energy and conduction band which is empty of higher energy. The gap between the two levels is called the forbidden energy gap which is a deciding factor for conductivity. for example in conductors these two bands overlap ,and in insulators there is a wide gap hence they are bad conductors ....
Do molecules of matter move in solids yes or no?
Atoms bond with each other covalently or ionically to form solids. Covalent bonding includes the sharing of two or more atoms. Ionic bonding transfers the electrons from one atom to another. The electrons are shared as the atoms are trying to fill there valence electron shell becoming a solid. Atoms bond with each other covalently or ionically to form solids. Covalent bonding includes the sharing of two or more atoms. Ionic bonding transfers the electrons from one atom to another. The electrons are shared as the atoms are trying to fill there valence electron shell becoming a solid.
Why atoms join together?
To share electrons in order to become balanced with either a full Valence shell or a completely empty Valence shell.
How do atom form chemical bond?
Around the nucleus of atoms circulate electrons. They are in shells. The electrons in empty shells are called valence shells. Now, if a shell isn't full, only partly, an atom will want to fill it. Hence, it will connect with an atom with too many electrons. Nature in general abhors energy and will always try to minimize it. It is energetically favorable for atoms with too many electrons to bond with atoms with too few in the valence orbit/shell. Sometimes it is more energetically favorable to share electrons. This type of bond is a covalent bond.

Method of bond formation for ionic?
Ionic compounds form between two atoms or molecules with opposite charges. Atoms/molecules get these charges when they either gain or lose one or more electrons to fill or empty their valence shell (they generally want either 8 or 0 electrons in their outermost shell).
How can you tell if an element will conduct energy?
Elements are in fact a bundle of energy if you will. I believe what your asking is How can you tell if an element will conduct electricity. If an atom contains less the the required atoms for its outer shell to become full and stable, it is classified as a conductor. Here's why: The atoms of a given element is composed of the protons, neutrons, and electrons. Electrons are the "electricity" part of an atom. These electrons orbit the protons and neutrons that are at the center of the atom. The electrons are in Valence shells, which is basically which orbit the electrons are on, the closest shell/orbit can contain only 2 electrons, and then it is said to be stable and full; the second valence shell/orbit can only contain 8 electrons, and then it is said to be stable and full; the third valence shell/orbit can only contain 8 electrons, and then it is said to be stable and full also ect.... Now, if we took the third valence shell, and it only contained 1 electron, it is NOT stable and full, so this 1 electron/electricity-part-of-the-atom is free to float around to other empty shells. This is due to the fact that the electrons always want to be in a stable shell/orbit. Some atoms of certain elements naturally contain a full AND therefore stable outer valence shell, (the furthest shell/orbit away.) If an atom contains less the the required atoms for its outer shell to become full and stable, it is classified as a conductor.
State the Octet rule?
The octet rule states that:Each atom in a chemical compound gains, looses, or shares electrons to form octet (8) electrons in their highest occupied energy level.They completely fill up the s and p orbitals.Also in a covalent bond, it achieves a more stable noble gas configuration.
What is the reactivity of an atom determined by?
It's determine by the vacancy (unfilled orbital) in the outermost shell of an atom.
