Para solucionar el ejercicio primero se debe conocer el número atómico de los elementos para determinar cuantos electrones tiene
Jet001 [13]

Answer:

El número atómico se refiere al número de protones o electrones de un átomo.

Explicación:

El número atómico se refiere a la cantidad de protones o la cantidad de electrones que giran alrededor de las capas u órbita de un átomo, por lo que el número atómico 7 representa que el átomo tiene 7 electrones o protones mientras que, por otro lado, el número atómico 17 muestra el número de electrones o protón. Solo hay dos electrones que entran en la primera órbita y en el resto de las capas tiene espacio para 8 electrones por lo que los átomos pierden o agregan electrones en su capa más externa para obtener estabilidad.

Which of the following best represents potential energy being converted to kinetic energy? HELP
TiliK225 [7]

Answer:

B) A drawn bow is released, causing an arrow to fly across the field

Explanation:

Potential energy can be thought of as "potential" to do something. For eg, putting a ball on top of hill causes the ball to have the potential to roll down the hill if released. Here the ball converts the potential energy into kinetic energy (energy of motion) to roll down.

Similarly, the bow has been stretched (potential to fly if released), and when its released, it converts the potential energy into kinetic energy.
