Answer:
The importance of crystal structure. The graphite-diamond mineral pair is an extreme example of the importance of crystal structure. These two very different minerals have exactly the same chemical formula (C), but the crystal structure of the two minerals is very different. In graphite, carbon atoms are bonded together along a flat plane, as shown in Figure 3.
Answer:
7 to 1
Explanation:
As you move from row ----- to row ------ in the periodic table, the atomic radius of the elements DECREASES.?
And we have 7 rows in a periodic table, so the answer has to either 1 to 7 or 7 to 1
Theoretically,
Atomic size increase as we move from top to bottom as an extra shell gets added up with every period.
SO, the answer is, 7 to 1
Alkaline Earth Metals and Alkali Reactive metals because they need more electrons to acquire octet.
