We know that Al2O3 is the formula of aluminium oxideWe also know that this formula comes from the criss-cross of the valencies of aluminium and oxygen and the electronic configuration of aluminium and oxygen is 2 8 3 and 2 6 respectivelySo, to complete their valence shell aluminium has to give 3 electrons and oxygen has to take 2 electronsBut, there are 2 atoms of aluminium and three atoms of OxygenNow, tell me that how these elements become neutral? How these elements give and take electrons?
No, looms are huge machinesYou can easily look these up on Wikipedia.
NoI believe the loom separates the wool.
a spinning wheel is used to bind individual fibres together to form a thread, a loom is used to bind threads together to form a fabric, Emily not all looms are huge, I have a lap loom that I carry in my shoulder bag with me so that I can work on my projects up town.
lol, im afraid you have gotten your self very confusedAl2O3This is derived from the OXIDATION numbers of Al and O2Al has an oxidation number of +3O2 has an oxidation number of 2-to work out the formula correct we criss-cross these and get the formula Al2O3so we get Al2 charge of 6+ and an O2 charge of 6-therefore the overall oxidation state of Al2O3 is 0, this is how the compound becomes neutralnow the actual electron configuration of these substances is actually: for aluminium it is 1s2,2s2,2p6,3s2,3p1for oxygen it is 1s2,2s2.2p4during the bonding of this substance theneach oxygen atom has 6 electrons in the shell and aluminium has 3electronstherefore there is 6electrons for aluminum as a whole to share with 3 oxygen atoms which as a whole have 18 electrons in the outer shells6 in each atomfor the outer shell it needs 2 electrons to fill itso the aluminium atoms give 2 electrons to the oxygen atoms forming ionic bondsthe aluminium atom are conected in the molecule by a strong intermolecular force caused by the difference in electronegativy with one being slightly negative and the other being slightly positivealso one of the 3 oxygen molecules has been given one electron by each aluminium atom therefore it forms an ionic bond with both atoms
NoA spinning wheel has, as the name implies, a wheel that spinsIt is used to spinning flax into yarnA loom is for weaving(You can weave the yarn you spun on your spinning wheel on your loom!)
