Hello,wey u troway oau thread ds yr put?

Odunnu: Wow! Congratulations.

I agree to it u r rite bt we av sum species of dogfish dat r mammal anywy...thks 4da observatn

olatosina: Bat has mammalia gland. The ans is C

Yes u rite,bt only fluorine hz an oxidatn numb. Of -1 only,odaz av -1,1,3,5 nd 7 reasn z dat da s nd p orbitals at da outermost shell of the elements r excitd to the nxt d-orbitals wich mak up of five hybrid electrn orbitals.bro datz da best of my knwledge,da questn evn cam out in da obj chem. Waecgce last yr. So itz nt daaat advanced (

mayorall: Remember they all have 1 as their valence electron......can u support with examples as evr1 is still learning

Dogfish

Grt pharmcst nd medics in da aoz signify by quoting 'great'

Yh correct!

Obinnau: C

Wel itz located unda da liver bt emulsifies in the duodenum trou da bile duct..thks 4da attempt!

Kunlexic: liver

U r 2correct bro,nd it also hz da greatst ionizatn energy,thk!

mayorall: Lymer

Oh,u made a mistak pfund z last wich z da most excited,u write brackett b4 pfund thks

larri: lyman series(ultra violet) followed by
balmer series(visible light)
paschen series(infra red)
pfund series(infra red)
bracket series(infra red)

Oh,wel datz the general assumptn nd knwlegde,bt they do have..itz only fluorine dat possess a single oxidatn number -1 cuz it only hz S-hybrid orbitals where odaz av bof s nd p.thks

mayorall: Halogens does not undergo variable oxidation state...their state is always -1

Oh,bro u made a mistak there..artery shld cum b4 arterioles thks u r correct!

larri: aorta, arterioles, artery, capillaries, venules, veins, vena cava

Thx bro,u r correct!
