Ad libitum [116K]

Answer:

Los elementos de la tabla periódica se distribuyen sobre la base de similitudes.

Explicación:

Los diferentes tipos de elementos se distribuyen en 8 grupos de tabla periódica en función de sus propiedades. Los elementos que tienen propiedades similares se colocan en el mismo grupo. Por ejemplo, el primer grupo de la tabla periódica son los metales alcalinos. Todos los metales alcalinos tienen algunas propiedades similares, es decir, un electrón en su capa más externa, alta reactividad y forma metálica, mientras que, por otro lado, los ocho elementos del grupo son gases nobles que tienen una capa más externa completa y no tienen reactividad.

Which of the following is NOT part of the kinetic molecular theory of gases?
kondaur [170]

A. There is very little empty space in a gas in not part of the kinetic molecular theory of gases.

Explanation:

The kinetic molecular theory of gases follows following points:

Kinetic energy does not change or get dissipated when gas molecules collide with each other. No attraction or repulsion between gas particles is observed. Particles of  gas are moving randomly in all directions. Temperature increase cause the rapid movement of gas particles.The gas particles are placed very far from each other as compared to liquid.

The empty space in a gas is large because gas gets compressed in the small volume of the container also.
