Question

Dados números quânticos do elétron diferencial do elemento que participa da constituição da hemoglobina( n = 3, L = 2, ml = -2, ms = +1/2). Determine o número atômico e a massa deste elemento que apresenta 42 nêutrons.

Answer 1

$Ola' \\ \\ Temos~os~n\acute{u}meros~qu\^anticos~que~s\~ao: \\ n=3 ~--\ \textgreater \ esta~na~camada~3\\ l=2~--\ \textgreater \ o~subnivel~\underbrace{s}_{0}~~\underbrace{p}_{1}~~\boxed{\underbrace{d}_{\mathbf{2}}} \\ \\ m=-2~-\ \textgreater \ n\°~quantico~magn\acute{e}tico-\ \textgreater \ \boxed{\uparrow \downarrow|~\uparrow~ |~\uparrow|~\uparrow~|\uparrow~} \\ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~-2~-1~~~0~+1~+2\\ s=+ \frac{1}{2} \\ \\ Ent\~ao~seria~o~subnivel~mais~energ\acute{e}tico~~\boxed{3d ^{6} }$

$fazendo~distribuic\~ao~eletr\^onica~temos: \\ \\ 1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{6} 4s^{2} 3d^{6} \\ \\ N\acute{u}mero~at\^omico~=\ \textgreater \ \boxed{Z=26} \\ \\ N\acute{u}mero~de~n\^eutrons=\ \textgreater \ \boxed{n=42} \\ \\ N\acute{u}mero~de~massa~=\ \textgreater \ A=Z+n \\~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ A=26+42 \\~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ \boxed{A=68} \\ \\ \mathbb{iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii}\\ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Espero~ter~ajudado!!$
