I've seen a few pics of homemade yarn dreads (though I always love seeing more!!), and I noticed that most people suggest using woolCan any type of yarn be used to make something at least similar to dreads, or is wool the ultimate way of going about it??
Does that mean they are located in the principal energy levels? Yes elements can only have a maximum of 8 valence electrons, so that can't be the caseNevertheless, it isThe n 1 level can only hold 2 electrons (s subshell), so there are only two elements on the first row of the periodic table: Hydrogen and HeliumHe has a full outer shell with 2 electronsThe n 2 level can hold up to 8 electrons (s and p subshells)There are 8 elements on row 2 of the periodic table, and the inert element Neon has 8 electrons in its full n 2 levelYour confusion probably starts at the n 3 levelIt has an s, p and d subshell holding 2, 6 and 10 for a total of 18 electrons altogetherYes that shell is indeed full with 8 electrons, when the s and p subshells are fullThat element is ArgonYet there's still a 3d shellWhen you get to the middle of the periodic table, you start filling that upRow 4 of the periodic table starts by filling up the 4s shellBut then starting with Sc (element 21), you start filling up 3d while you have only 2 electrons in the 4sAt Zn (element 30) the 3d shell is full, the n 3 shell is full, and then you start filling up the 6 electrons in the 4p shellThere's still a 4d shell, but you don't start filling that till the middle of the n 5 rowAnd there's a 4f shell which is being filled from elements 57-70 which is after the beginning of the n 6 rowAt this point my memory of chemistry class breaks downI know this order has to with energy, that 3d is higher energy than 4s, and that 4d is higher energy than 5s, and that's why it fills afterI don't recall why an element with 4s and 4p is inert though, even though there's a 4d levelIt also has to do with energy I suppose.
Yeah I agree with the person aboveAlso yarn dreads tend to look really cheap.
