Answer:
Explanation:
Thus, total 4+4=8 C atoms are present per unit cell of diamond. Carbon has an electronic arrangement of 2,4. In diamond, each carbon shares electrons with four other carbon atoms - forming four single bonds.
 
        
             
        
        
        
In any case, your mass would be<em> 68 kg </em>no matter what

Answer:
Gallium
Explanation:
Gallium is one such element used as a do/pant in a p-type semiconductor. 
A do/pant is an impurity added to a semi-conductor used to alter its properties. Semi-conductors have a wide range of applications. They will conduct heat and electricity only under certain conditions. This property is highly desirable and find a wide application in electronics. 
For p-type conductors, they are best do/ped with elements with 3 valence electrons. These are group 3 elements. From the choices, only gallium belongs to this group. 
Other elements given are good do/pants for n-type semiconductors. They have 5 valence electrons.
