Answer:
Diamond
Explanation:
Diamond has covalent bonds, which makes it a non-metal.
However, it also has a tetrahedral structure, which holds its C atoms together by strong forces, thus making it hard.
Diamond also has free-moving electrons due to its tetrahedral structure, thus making it possible to conduct electricity.
Answer:
the experimental variable
Explanation:
Answer:
(C) Oxygen because it has the strongest attractive force and the largest
electronegativity
Explanation:
Oxygen will be most reactive
configuration = 
As oxygen need only two electrons to complete its octet.
Oxygen will have stronger force than nitrogen as it will tend to pull electrons more to complete its octet. Also along the period electronegativity increases so oxygen has higher electronegativity than nitrogen
Answer:
Carbon
Explanation:
I just finished this and that's what I got from my periodic table.
