Prueba con tus argumentos quienes sufren mas con la violencia?
Given :
a. 
b. 
c. 
d. 
.
To Find :
Find the most likely vale of x for each one .
Solution :
a .
Because boron have valency of 3 .
So , x = 3 .
b .
Valency of carbon is 4 .
x = 4 .
c .
Valency of nitrogen is 3 .
Therefore , x = 3 .
d .
Now ,we know valency of carbon is 4 and hydrogen is 1 .
Also , two hydrogen are already there .
So , only 2 electrons left to share .
Since , chlorine have valency of 1 .
Therefore , only 2 electrons of chlorine can connect .
x = 2 .
Hence , this is the required solution .
Find a periodic table of elements.<span> This is a color-coded table made up of many different squares that lists all of the chemical elements known to humankind. The periodic table reveals lots of information about the elements — we'll use some of this information to determine the number of valence electrons in the atom we're investigating. You can usually find these inside the cover of chemistry textbooks. There is also an excellent interactive table available online </span>here<span>.</span>
