i live in an apartment and can hear my neighbors footsteps and noise from abovewas recommended having celluloseblown into the ceilings.
Ca: will lose 2 electrons F: will gain 1 electron AL: will lose 3 electrons O: will gain 2 electrons
A: Calcium (Ca):- forms Ca2+.it loses 2 electons.its an electro+ve ion B: Fluorine (F):- forms F-.gains 1 electron in its last shellC: Aluminum (Al):- forms Al3+.loses 3 electronsD: Oxygen (O):- forms O2-.gains 2 electronshope u understood it
I think not a whole lot of help The drywall on your ceiling is nailed to the bottom of the floor joice and their flooring is nailed to the topSo the vibration (noise) of walking gets transmitted right throughInsulation would dampen only the noise in the air space but my experience says it will reduce it a little but not address the real source.
calcium loses 2 electrons (Ca++) Flourine Gains one (Fl-) Aluminum loses 3 (Al+++) Oxygen loses 2 (O-) Remember that they want to have full outer shell, and a full shell is usually 8 electronsso if it has 1, it's easier to lose it than to gain 7 moreor if has 7 it's easier to gain one more than to dump all 7.
Ca 2+ Loses 2 electrons F- Gains 1 electron Al 3+ Loses 3 electrons O 2- Gains 2 electrons An easy way to recognize this besides doing loads of chemistry problems is looking at the periodic tableThe main thing here are the valence electronsThe of electrons lost or gained depends on how many electrons are needed to fill the outer electron shellIf you have a periodic table handy, go across a period (bypassing the transition metals) and the valence electrons should look like: 12 3 4 5 67 of valelectrons HBeB.CN O .F element +1.+2+3-4-3-2 .-1 charge of ion It's easier for metals like Na and Li to lose an electron than it is to gain and vice versa with nonmetals like F and Cl which have 7 valence electrons.
