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.
We see that colour which is reflected by the surface because the object is made up of that colour.
<h3>What is the colour of lemon in white light?</h3>
A lemon in white light appears yellow to the human eye because yellow light is reflected by the lemon's surface while all other wavelengths of light are absorbed.
If the same lemon is placed into red light. It will appear to look red. This occurs because the red light will be transmitted by the lemon's surface and red light will be reflected to your eye.
So we can conclude that we see that colour which is reflected by the surface because the object is made up of that colour.
