The aluminum combusted with oxgen forming aluminum oxide...the reaction formula is:
4Al + 3O2---> 2Al2O3
there is not eight valence electrons so the element is not stable
It is trying to fil its outer most energy level
Because it was in a mixture along with cellulose butyrate acetate and iron oxide. This mixture burns EXTREMELY easily.
rocket fuel
alimnum has a low melting point and the powdered paint is highly flameble.
Answer No. Aluminum cans are made from an aluminum alloy. Aluminum powder is a different form and was mixed with glue to coat the fabric of the airships.
In general, boron will form 3 covalent bonds, using each of its 3 valence shell electrons (sharing them). This will of course violate the octet rule, but obeys the sextet rule, and this is what makes boron stable. It (along with aluminum, eg.) do not obey the octet rule.
The octet rule cannot be satisfied in molecules whose total number of valence electrons is an odd number.There are also molecules in which an atom has fewer, or more, than an octet of valence electrons.
The octet rule is a simple rule of thumb that states that atoms tend to combine in such a way that they each have eight electrons in their valence shells, giving them the same electron configuration as a noble gas. The rule is applicable to the main group elements. In simple terms, molecules or ions tend to be most stable when the outermost electron shells of their constituent atoms contain eight electrons.
The molecule SF4 doesn't have eight electrons like most atoms, it can expand the octet because sulfur has 6 valence electrons and each fluorine only needs one electron to share with sulfur so that leaves to remainder.
D. Noble Gases
Maybe because aluminum atom in Alcl3 does not attain octet arrangement... thus, it undergoes dimerisation to produce al2cl6, where the aluminum atom achieve an octet electronic configuration.
Aluminum must lose 3 electrons to satisfy the octet rule. Once it does this, it becomes the Al+3 ion, and is isoelectronic with noble gas neon.
its called an octet
Na atom ion has an electronic configuration 2,8,1 On losing one electron it forms Na+ cation, with the configuration of 2,8 thereby obeying octet rule.
The compound containing aluminum and nitrogen is called aluminum nitride and has the formula AlN. The aluminum atom loses its three valence electrons, and the nitrogen atom will gain the three valence electrons from the aluminum atom, and add them to its valence electrons, forming an octet. Refer to the related link below for an illustration.

An octet.
Some elements that are known to violate the octet rule are: Hydrogen, Helium and Lithium (two electrons) Aluminum and Boron (less than octet but will form an octet if possible), Period 3 elements with p orbitals (more than an octet using empty d orbitals), noble gas compounds (more than an octet), and elements like nitrogen with an odd number of electrons (form free radicals when octets are not possible).
A group of eight anything is called an "octet".
Az important rule: any octet has to have eight parts, otherwise it is not an octet.
It is possible because of dative/ coordinate bonding. Basically, because the aluminium atom in AlCl3 is electron deficient and the nitrogen atom in NH3 has a lone pair of electrons, N donates one pair of lone electrons to Al for sharing in order for Al to obtain a stable octet configuration. Hence a dative/ coordinate bond is formed.
The noun 'octet' is a word for a group of eight. The noun 'octet' is not a standard collective noun for a specific group, but can be used as a collective noun for any group of eight; for example, an octet of singers, an octet of swans, etc.
