Determinar los números cuánticos del electrón desapareado en el átomo del cloro (Z = 17) y diga si es paramagnético
Musya8 [376]

Answer:

n = 3

l = 1

ml = +1

ms = +1/2

Es paramagnético

Explanation:

Siguiendo las reglas de llenado de orbitales, los 17 electrones del cloro se llenan así:

1S = <u>⇅</u>

2S = <u>⇅</u>

2P = <u>⇅</u> <u>⇅</u> <u>⇅</u>

3S = <u>⇅</u>

3P = <u>⇅</u> <u>⇅</u> <u>↑</u>

<u />

El número cuántico principal n, es el nivel energético donde se encuentra este electrón:

n = 3 (Porque está en el orbital 3P

El número cuántico secundario, l, para el orbital 3P es  = 1:

l = 1

El número cuántico magnético, ml, es determinado por la posición del electrón. Como está en el tercer orbital 3P:

ml = +1

Y el número cuántico de spin, ms (↑ = +1/2; ↓ = -1/2)=

ms = +1/2

Dado que el último electrón se encuentra desapareado, el cloro es paramagnético dado que el espín de el último electrón no tiene su electrón complementario haciendo que este compuesto pueda interactuar con un campo magnético.

When water condenses on the side of your glass of cold lemonade is it a endothermic or exothermic reaction?
LuckyWell [14K]

Answer:

It is an endothermic process because the glas of lemonade is gaining energy.

Explanation:

The condensation of water is <em>not a reaction</em>, because the water is not changed into something else. We should call what’s happening a <em>process</em>.

The glass of lemonade is the system, and the rest of the universe is the <em>surroundings. </em>

When the water molecules in the atmosphere hit the sides of the cold glass, they give up some of their kinetic energy and condense into droplets of water.

The system is gaining energy from the surroundings, so the process is endothermic.
