Which ions—positive ions or negative ions—tend to be larger and why?

Chemistry
1 answer:
Sedbober [7]4 years ago

<span>Generally negative ions is known as anion and positive ions is known as cation. Anions will gain an electron to fill in an electron shell but cations will lose an electron to fill in an electron shell so that cation by losing the electron the ionic mass will be lower where as for anion by gaining an electron the ionic mass will be higher so that atom will be larger.Therefore negative ions tend to be larger than positive ions.</span>

1. Que factores provocan la oxidación?
Katyanochek1 [597]

Answer:

Mira la explicación.

Explanation:

Hola,

Las reacciones de oxidación se definen como aquellos procesos químicos en las cuales uno de los elementos involucrados sufre un aumento en su estado de oxidación, causado por el efecto de un agente oxidante, el cual es capaz de aceptar los electrones perdidos por dicho elemento oxidante. Dentro de los factores promotores de la oxidación se pueden encontrar:

1. Presencia de oxígeno gaseoso: al ser un agente oxidante fuerte, es capaz de recibir electrones de casi cualquier sustancia.

2. Presencia de humedad: a la larga, cuando una sustancia reacciona con agua tiende oxidarse ya que el agua posee oxígeno y como se vio anteriormente, es el principal promotor de oxidación.

3. La presencia de algunas sales iónicas como cloruro de sodio también promueven la oxidación, por ello es que no debemos introducir joyería al mar, debido a que esta salinidad induce reacciones electroquímicas que son capaces de oxidar metales.

4. Reacciones con ácidos oxidantes: ácidos como el nítrico, son oxidantes fuertes que tienen la capacidad de disolver metales (oxidarlos) y formar nitratos, por ejemplo el cobre en presencia de ácido nítrico, sufre una oxidación bastante violenta.

Saludos!

Why is not used at nuclear plant as a soverce for electrical energy
nikitadnepr [17]
The biggest reason is radioactive wastes. Nuclear power generated radioactive wastes like Uranimum, plutonium and amercium that inhibits gene expression and causes cancer to the environment. Nuclear plants use to release these wastes into the oceans, and it causes fishes to exhibit gender change, 3 eyes, 2 tails etc. The impact on human shows signs of serious blood, liver and lung cancers. 

There are currently no way to get rid of these wastes as they take hundred thousands of years to decompose. 

Another reason is they cause a small amount of green gas emission. Releases CO2 to the sky. They exhibit radioactive gas emission as well (causes cancer) .
