when an electron gets closer to the nucleus does the attraction or repulsion grow weaker or stronger?

Chemistry

klasskru [66]3 years ago
6 0

Answer:

Weaker

Explanation:

Since the charges on nucleus and electron are opposite in nature, an attractive force exists between them. It is true in generally, that when objects are made to move closer together in the direction of an attractive force, potential energy decreases (and increases whenever attracting objects are force to move apart).

True or False: The ticketing area is more secure than the area beyond the security check point.
Natali [406]

The answer is false.

That is the ticketing area is more secure than the area beyond the security check point is false rather than the area beyond security check point is more safe than the ticketing area.

There is more security in the area beyond security check point because of anti-terrorism actions .

Cuál o cuáles de las siguientes características son correctas para la mayoría de los compuestos del carbono?
garik1379 [7]

Answer:

Todas son correctas

Explanation:

I) Los compuestos del carbono son solubles en disolventes no polares como el hexano, benceno, éter, etc. <em>VERDADERO. </em>La mayoría de los compuestos de carbono son apolares, y basados en la regla: Similar disuelve similar, podemos presumir que la mayoría de compuestos de carbono se disuelven en solventes no polares.

II) Los compuestos del carbono generalmente presentan puntos de fusión y de ebullición bajos. <em>VERDADERO. </em>Al ser sustancias apolares, sus fuerzas electrostáticas son bajas. De la misma manera, como su masa atómica es pequeña, las fuerzas de Van der Waals son despreciables haciendo que sus puntos de fusión y ebullición sean bajos respecto a sustancias de estrucutra similar.

III) La gran mayoría de los compuestos del carbono son combustibles, sean estos, gaseosos, líquidos o sólidos. <em>VERDADERO. </em>Los gases (Como el gas natural) son combustibles usados para cocina. Los líquidos (Como la gasolina) son combustibles y bastante inflamables. Los sólidos (Como la madera) se usan como combustibles para hacer asados o son el combustible en incendios forestales.

IV) El enlace covalente es característico de los compuestos del carbono. <em>VERDADERO. </em>La polaridad del carbono es neutral haciendo que la mayoría de los enlaces que forma sean covalentes.

<h3>Todas son correctas </h3>

please help I don’t understand the difference between ammonium and ammonium ion. I possibly did 9.a) correct but part b is a bit
ozzi

You may find the electron diagram of ammonia and the ammonium ion in the attached picture.

Explanation:

Ammonia NH₃ have covalent bonds with the hydrogen atoms in which for each bond one electron comes from nitrogen atom (blue dot) and the other from the hydrogen atom (red dot). You may see that the nitrogen remains with the lone pair of electrons that does not participate in bonding.

Ammonia NH₃ have a basic character and is able to accept a proton H⁺ from an acid to form the ammonium ion NH₄⁺. The fourth bond formed its called a coordinative-covalent bond that is created only with the nitrogen lone pair of electrons (blue dots).
