It is a covalent bond because both hydrogen and oxygen are nonmetals, and whenever nonmetals bond, it's always covalent.
The water molecule has a covalent bond. Since there is no other kind of water, "covalent water" is redundant. That's what water is. There is no ionic water (although ionic compounds often dissolve in water).
The bonds are ionic or covalent.
As a generalization, ionic bonds are much stronger than covalent bonds.
ionic or even covalent bonds
Sodium hydroxide has ionic bonds. A compound never is any kind of bond.
These bonds are ionic or covalent.
Covalent bonding
It depends what kind of bond. A covalent bond is barely affected at all. The strength of an ionic bond is essentially reduced to nothing because ionic compounds dissolve readily in water, which breaks all the ionic bonds.
The kind of bond that results when electron transfer occurs between atoms of two different elements can be considered covalent, polar covalent, or ionic. The type of bond will depend upon the identities of the elements and their electronegativity's.
Chemical bonds can either be covalent or ionic.
These are the electrons from the outer shell of an atom.
Sodium hydroxide has ionic bonds. A compound never is any kind of bond.
