H and H
Covalent.
With itself or with 5A group
Compounds with covalent bonds are generally more dangerous more open flames, because they are more likely to combust. Ionic compounds such as salt usually do not react as nearly much to flame. This results due to the different natures of the bonds.
Covalent bonds are mostly formed between two non metal atoms. They are formed by sharing one or more valence electrons and with creating hybrid orbits. A covalent bond between two likely atoms would be non polar.
The bond between O and F would be a covalent bond (dative/coordinate), if in fact OF existed. More likely it would exist as OF2 (still covalent bonds).
Oxygen
H and H
Covalent.
It represents the boundary between what is considered to be an ionic or a covalent bond.

The element silicon would be expected to form 4 covalent bond(s) in order to obey the octet rule. Si is a nonmetal in group 4A, and therefore has 4 valence electrons. In order to obey the octet rule, it needs to gain 4 electrons. It can do this by forming 4 single covalent bonds.
No, they are both halogens and nonmetals with a electronegativity too close together to form an ionic bond. They, if ever bonded, would form a covalent, or polar covalent bond.
Hydrogen bonds are weak, but they are able to hold the backbones together. If covalent bonds held the templates together instead, the bonds would be even weaker and would likely break.
The formual is suspect- such a compound would be covalent.
