Answer:
1. Magnesium and oxygen atoms bond to form an ionic compound; this is evident because one forms a cation and the other an anion. When an ionic compound is formed, one atom "steals" an electron (or electrons) from another. In this case, an oxygen atom (which is pretty electronegative by the way) "steals" 2 electrons from a magnesium atom. The resulting oxygen anion and magnesium cation attract one another to form a bond (more specifically, an ionic one).
2. The oxygen atom needed two sodium atoms to bond because it needs two additional electrons to achieve a stable octet of electrons. 1 sodium atom provides 1 additional electron after it is "stolen" by oxygen, so 2 sodium atoms are needed in total to form the bond.
3. The magnesium atom needed two fluorine atoms to bond because it needs to lose two electrons to achieve a stable configuration/octet of electrons. 1 fluorine atom "steals" one electron, so 2 are needed in total.

Explanation:
The rock cycle plays an important role in the process of calcium carbonate formation is that it is built by plankton and corals. Therefore, it is true that the rock cycle is influenced by the biosphere processes as well as the geological processes.
<h3>What is the significance of the rock cycle?</h3>
A rock cycle can be described as the process that leads to the formation of minerals and chemical elements because of the occurrence of natural processes near the oceans and water bodies.
Substances like calcium carbonate (CaCO₃) are one of the influential formations in the rock cycle. The formation of calcium carbonate is highly contributed by the plants and animals to form the plankton as well as the corals on reefs.
Therefore, the significance of the rock cycle has been aforementioned.
