A negatively charged particle with an electronic arrangement of 2,8 could beA- a flouride ionB - a sodium atomC - an aluminium ionD - a neon atom It cant be the atoms because they are not charged so its A or CThe answer is A but how is it not C because can Aluminium not lose its 3 extra electrons to have 2,8?
2, 8 is pretty archaicA better representation of the electrons is 1s2, 2s2 2p6 Either way, it's the electron configuration of neonThe fluoride ion and the aluminum ion are both isoelectronic with neonThat is all three, Ne, Al3+ and F- all have 10 electrons (which is what isoelectronic means)Yes, Al can lose three electrons to give the Al3+ ionBut your question says negatively charged, so only F- will answer the question Follow up The answer can't be D because the neon atom is neutralThe question says negatively charged.
this looks like it was a supposed to be a storage room or a shedif that what is was maybe you should consider demo and starting from scratchi am not being rude or mean.
You don't need to put insulation if it's only a half height wallThere's no pointPut some diagonal strapping or at least nail a temporary stud diagonally across your walls while you sort out you cladding or the whole thing will blow overI'm not joking about that.
I'd start with plans from Home Depot, or one of the specialty books they sellJust build the base, and modify it for your driftwood to fitThere's so many different gazebo layouts, you'd need to pick your own preference thereBut most driftwood isn't really going to be long enough for the joists or beamsYou might have to just use the driftwood as add-on decoration.
