¿Cuál es la diferencia entre electrones internos y electrones externos? *

Chemistry
1 answer:
Fudgin [204]3 years ago
3 0

Answer & Explanation:

Los electrones externos se encuentran más lejos del núcleo. El número de electrones en la capa más externa (electrones de valencia) de un átomo en particular determina su reactividad (tendencia) a formar enlaces químicos con otros átomos.

Los electrones internos son los más cercanos al núcleo. Protegen los electrones de valencia del núcleo, reduciendo la carga nuclear efectiva.

A researcher dispenses distilled deionized water from a 20-ml volumetric pipet into an empty 8.4376 g weighting bottle. If the t
bonufazy [111]

As given that some volume of water has been dispensed say "x mL"

The initial weight of bottle =8.4376 g

The final weight of bottle + water =28.5845 g

So weight of water transferred = 28.5845 g - 8.4376 g = 20.1469 g

Now there is a relation between density, mass and volume

density = mass / volume

Therefore

Volume = mass / density

So volume of water dispensed = mass dispensed / density =20.1469 g / 0.9967867 g/ml.

Volume of water = 20.2118467 mL
