GREYUIT [131]2 years ago

A tree is able to speed up erosion because it break up rocks. This can happen as it’s roots grow through rocks, the water breaks through rocks, etc.
It can slow erosion down because it can act as a barrier to the elements that erode.

<u>Mendeleev </u><u>positioned elements in the periodic table in</u><u> increasing order </u><u>of their atomic numbers, such that </u><u>elements </u><u>having identical chemical properties and characteristics plunge into the </u><u>same group.</u>

What is Mendeleev's periodic table called?

  • In order to represent similarities and patterns in the behavior of elements, Mendeleev created the periodic table, which is an arrangement of elements in an increasing atomic mass order in tablet form.
  • Mendeleev stated that "Element characteristics are a periodic function of their atomic weight" in his renowned periodic law.
  • The Periodic Table of Mendeleev is a table that Mendeleev created to list elements in the order of their atomic weights.

  • Mendeleev discovered that there were two elements with atomic weights between 65.2 and 75 because he found it very satisfying that the properties of the elements were more similar and closer to this level.
  • He also imagined having other elements with possessions similar to those of these other elements.
  • In the periodic table, he left a blank for these two elements until they were finally discovered in their true existence.

What’s the correct answer
Fed [463]
The correct answer is: 
_________________________________________________________
    " F  and Br , because they are in the same group" .
_________________________________________________________
Note:
_________________________________________________________
Choice [B]:  "F and Br ; because they are in the same period" ; is incorrect; since  "F" and "Br" are not in the same "period" (that is, "row").
______________________________________________________
Choice [C]:  "Na and Mg; because they are in the same group {"column"} ;  is incorrect; since:  "Na" and "Mg are NOT in the same group {"column"].
_______________________________________________________
Choice [D]:  "Na and Mg" ; because they are in the same period {"row"}; is incorrect.  Note:  "Na" and "Mg" are, in fact,  in the same period {"row"}. However, as aforementioned, {Mg and Na} are not in the same group {"column".}.  

Note:  The similiarities in physical and chemistry properties among elements are determined and organized — or tend to be so—by "groups" {"columns"} — NOT by "periods" {rows}.
