Someone. or something will get hurt
Answer:
a. True
Explanation:
In the periodic table , all the elements are placed in a certain fashion , i.e. , with increasing atomic number.
Since ,
The element lithium and nitrogen are placed , in group 1 and 15 respectively.
as we go from left to right , across the group , the atomic radius decreases ,
Because ,
As , we go left to right , the number of electrons increases in the same shell , and proton too increases , which in turn increases the nuclear attraction , and the nucleus holds on to the electrons more firmly , and hence , the size reduces , as the electrons increases , in the same shell.
Hence, the given statement is true.

Answer:
can only be determined experimentally.
Explanation:
In the early days of inorganic chemistry, the structure of complex ions remained a mystery hence the name ''complex''.
These ions appear to have structures that defied accurate elucidation. However, by diligent laboratory investigation, Alfred Werner was able to accurately determine the structure of cobalt complexes. As a result of this, he is regarded as a pathfinder in coordination chemistry.
Hence, the structure of complex ions can only be determined experimentally.
It is less dense than most other material and has a higher melting point so it will not melt.
