Which statement about schrodingers theory of the atomic model is true?
Svetach [21]

I found the complete question:

Which statement about schrodingers theory of the atomic model is true?

A. it proved that the nucleus of an atom is positively charged.

B. it was the first theory to discuss the existence of electrons.

C. it explained the odds of finding the position of an electron.

D. it assumed the electron cloud to be heavier than the nucleus.

Answer:

C. it explained the odds of finding the position of an electron.

Explanation:

Erwin Schrodinger formulated the wave equation of electrons. His wave equation highlighted the probability of where an electron can be found or located in an energy level.

The region of maximum probability of where an electron is located is referred to as an electron cloud or an orbital.

Brums [2.3K]

Answer:

Explanation:

No.

Las propiedades físicas de los materiales y sistemas a menudo se pueden clasificar como intensivas o extensivas, según cómo cambia la propiedad cuando cambia el tamaño (o extensión) del sistema. Según la IUPAC, una cantidad intensiva es aquella cuya magnitud es independiente del tamaño del sistema, mientras que una cantidad extensiva es aquella cuya magnitud es aditiva para los subsistemas. Esto refleja las ideas matemáticas correspondientes de media y medida, respectivamente.

Una propiedad intensiva es una propiedad a granel, lo que significa que es una propiedad física local de un sistema que no depende del tamaño del sistema o de la cantidad de material en el sistema. Los ejemplos de propiedades intensivas incluyen temperatura, T; índice de refracción, n; densidad, ρ; y dureza de un objeto.

Por el contrario, propiedades extensivas como la masa, el volumen y la entropía de los sistemas son aditivas para los subsistemas porque aumentan y disminuyen a medida que crecen y se reducen, respectivamente.  

Estas dos categorías no son exhaustivas, ya que algunas propiedades, físicas no son exclusivamente intensivas ni extensivas. Por ejemplo, la impedancia eléctrica de dos subsistemas es aditiva cuando, y solo cuando, se combinan en serie; mientras que si se combinan en paralelo, la impedancia resultante es menor que la de cualquiera de los subsistemas.

¡Espero haberte ayudado!  :)
