Covalent bonding occurs in nonmetals because nonmetals have high electronegativity values and tend to gain electrons from other elements to reach a stable electron configuration. In covalent bonding, nonmetals share electrons to achieve a full outer shell and form stable molecules or compounds. Metals, on the other hand, typically lose electrons to achieve a stable electron configuration through ionic bonding.
between metals
Covalent... Ionic bonds take place only between metals and non-metals whereas covalent bonds occur between non-metals only. Since Carbon, Hydrogen and Oxygen are non-metals, the type of bonding occurring here is covalent
Covalent bonding typically occurs between nonmetals. In covalent bonds, atoms share electrons to achieve a full outer shell and form stable molecules. Metals usually form metallic bonds, where electrons are delocalized and shared between all atoms in the metal lattice.
Elements do not "occur" in bonds. Instead, elements form bonds between themselves. If the question means "Between what types of elements are covalent bonds likely to form?", the answer is "elements with very similar electronegativities". The smallest possible difference between electronegativities is that between two atoms of the same element, such as is present in the diatomic elements hydrogen, oxygen, nitrogen fluorine, chlorine, bromine, and iodine and in the polyatomic element carbon in its diamond crystal form.
Sulfur and Oxygen are both non-metals so their chemical bond is a covalent one.
Covalent bonds are formed between non-metals only, while ionic bonds are formed between metals and non-metals. Since calcium is a metal and iodine is a non-metal, this would not be a covalent bond.

The valence electrons are the only electrons involved in chemical bonding. In covalent bonding sharing occurs In ionic bonding electrons are tranferrred In metallic bonding they are deloclaised across the lattice
Magnesium Chloride cannot be formed by covalent bonding because there is a metal element. Covalent bonding occurs only when two or more non-metals bond; thus Hydrogen Fluoride would be formed by covalent bonding.

Elements don't have bonds, only compounds do.
Carbon tetrachloride is a covalent compound.
A compound composed only of nonmetals is called a covalent compound. These compounds are formed by sharing electrons between atoms, rather than transferring them as in ionic compounds. Examples include carbon dioxide (CO2) and water (H2O).
