Answer:

Temperature is a gradation but day/night is all-or-nothing

Explanation:

Temperature change is progressing. I.e from Hot to cold, it moves gradually along a gradient. But Night and Day is a two edged variance. It's either day or night, also know as the All-or-nothing .

iren2701 [21]

Answer:

A coral reef can be described as an ecosystem of the ocean which is made up by reef-building corals. Coral reefs benefit the environment in a number of ways, one of them is protecting the shoreline. <em><u>Coral reefs tend to absorb most of the waves from the ocean and so help the coastline from erosion. It reduces the chances of ocean water waves to destroy the crops and buildings nearby and hence prevents erosion. </u></em>

¿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.
