¿Qué se puede agregar a un átomo para hacer que un electrón sin valencia en el átomo se convierta temporalmente en un electrón d
NNADVOKAT [17]

Energía.

Explicación:

Generalmente, los electrones giran continuamente en las capas de los átomos. Si estos electrones se encuentran en las capas más externas de un átomo, se denominan electrones de valencia.

Son necesarios para las reacciones químicas de un átomo en particular con otro, a través de sus pérdidas o compartidas.

En los átomos sin valencia, sus capas más externas no tienen electrones en sus capas más externas, tales átomos son estables.

Sin embargo, si se suministra cierta cantidad de energía a dicho átomo, el electrón gana energía y, por lo tanto, se excita.

Por lo tanto, se mueven de niveles de energía más bajos a niveles de energía más altos, y hacen que el átomo sin valencia se convierta en valencia temporalmente, a medida que se mueven hacia la capa más externa.

Answer:

Energy.

Explanation:

Generally, electrons revolves continuously in the shells of  atoms.if these electrons are located in the outer most shells of an atom,they are refereed to as the Valence electrons.

They are needed for chemical reactions of a particular atom with another,through their loses or sharing.

In Non -valence atoms their outermost shells do not have electrons at their outermost shells,such atoms are stable.

However, if  certain quantity of energy is supplied  to  such atom, the electron  gains energy and therefore becomes excited.

They therefore move from lower energy levels to higher energy levels,and makes the non- valence atom becomes valence temporarily, as they move into the outermost shell.

Explain how water pollution can also indirectly occur as an offshoot of soil pollution. Give at lease 2 examples in your respons
Murljashka [212]

Answer and Explanation:

The use of pesticides and fertilisers leads to soil pollution. These are often not easily biodegradable and so they accumulate in the soil and kill soil organisms. Rain water run-off may carry such chemicals into streams,rivers and lakes. These toxic chemicals can eventually find their way into the tissues of different organisms associated with aquatic ecosystem.

The accumulation of silt due to poor cultivation along the river banks and the destruction of riverine leads to soil erosion. The deposition of silt near the mouth of river makes the water turbid and so impedes the penetration of sunlight. This affects the aquatic organisms and pollute the water.
