Aneli [31]

Answer:

$\huge\boxed{\sf OH-}$

<u>For example:</u>

NaOH ⇄ Na⁺ + OH⁻ (So, it is a base)

Indique el valor de los números n,l,m y s para el último electrón de ₇N.(1 pt c/u) n = _____ l = _____ m = _____ s =_____

tia_tia [17]

Answer:

n = 2

l = 1

m = 1

s = +1/2

Explanation:

₇N tiene la configuración electrónica;

1s2 2s2 2p3

Esto implica que este último electrón tiene los siguientes números cuánticos;

n = 2

l = 1

m = 1

s = +1/2

Este último electrón estará en un orbital de 2pz como lo muestran los números cuánticos enumerados anteriormente.
