I have knitted a scarf for a friend and ironed it since the sides always curl in, but now the ends are stretched and the wool fibre flattenedHow do I get it back to its original condition, curling in sides and all?I have put it through a warm wool wash but dried it in front of the heater which hasn't helped.
Not to my knowledge it shouldn'tAfter losing the first you would a stable 3s^2 After losing two electrons you would have a fairly stable 3s^1 After losing three you would have a very stable 2p^6 But if it's to do with valence electrons then yes i suppose it easier for Al just to give up it's three valence electrons to have an octet configuration, rather than carry an extra electron in another energy level - very not stable
It isn't, despite the fact that three people have explained why it is!! The figures below show how much energy (I.E Ionisation Energy) is required to remove the 1st, 2nd and 3rd electronYou can see for yourself that the energy requirement is greater, therefore loss more difficult, each time 1st I.E 577 kJ mol-1 2nd I.E 1820 kJ mol-1 3rd I.E 2740 kJ mol-1
because the first electron of this 3 electrons is in 3s4 and other are in 3p4.so the energy of 3s4 is higher than 3p4.so the first electron`s territory is top of remaining electrons.
It is all based upon the outer most electron orbitalsAl has a set of 3 valence electrons in its neutral state, so it can lose 3 electrons to obtain a noble gas electron field (the most ideal electron field)If it loses only 2 electrons, then there is still one electron out in the outer most valence field and thus, is not in a noble gas configuration.
You need to wash it again, but this time put it flat on a towel to dryYou can shape the side to keep them straight and once it dries it should retain the shape.
