Two atoms of H combines with 1 atom of O by covalent bond. Water H2O is produced.
A covalent bond would be formed between an oxygen and hydrogen atom. This bond is formed by the sharing of electrons between the atoms.
Oxygen forms either covalent or ionic bonds, depending upon what it is bonding with.
Hydrogen and oxygen are the reactants and water is the product.
When hydrogen, a nonmetal, bonds with oxygen, another nonmetal, they form a covalent bond. This results in the formation of a molecule of water (H2O), where the two atoms share electrons to achieve a stable electron configuration.
That would be a description of water, i.e. H2O
A covalent bond would be formed between an oxygen and hydrogen atom. This bond is formed by the sharing of electrons between the atoms.
For a covalent bond electrons are shared between two atoms.
The hydrogen and oxygen in water mainly have covalent bonds. However there are some ionic bonds; otherwise, water would not have a pH. It also has some hydrogen bonding, which raises the temperature of its melting and boiling.
The bond between oxygen and hydrogen would be classified as a polar covalent bond due to the difference in electronegativity between the two atoms. Oxygen is more electronegative than hydrogen, leading to an uneven sharing of electrons in the bond.
Oxygen forms either covalent or ionic bonds, depending upon what it is bonding with.
In pure water, you would find covalent bonds holding the hydrogen and oxygen atoms together within each water molecule. Additionally, there would be hydrogen bonds between neighboring water molecules.
A hydrogen bond would form between hydrogen and oxygen atoms. Hydrogen bonds are weak electrostatic interactions resulting from the attraction between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom.
Nonmetals such as carbon, oxygen, nitrogen, and hydrogen would form covalent bonds with sulfur. These elements are able to share electrons with sulfur to complete their outer electron shells.
Water has a higher boiling point than would be expected for a covalent compound of that molecular weight, because the water molecule is highly polar, and forms what are known as coordinate covalent bonds between water molecules. The polarity of the water molecule is the result of its shape, not the result of the single covalent bond that exists between the oxygen atom and each of the two hydrogen atoms.
Carbon and oxygen as CO2 ( O=C=O) or carbon and hydrogen , as CH4 or oxygen and hydrogen , as H2O ( H-O-H) or nitrogen and hydrogen as NH3 or sulphur and ixygen as , SO2 ( O=S=O) Are just a few pairs of atoms that form covalent compounds. There are many more pairs. However, as a general rule any pair of atoms from the right of the Periodic Table form covalent compounds. Metallic elements to the left and centre of the Periodic Table tend to form ionic compounds.
Carbon generally form four covalent bonds.So this leaves two covalent bonds for oxygen, exactly enough for the stable oxygen bonding with one double bond. '-' is single, '=' is double: C(-H)(-Cl)(=O) which is named 'chloromethanal'
P2H4 is a covalent compound. It is made up of nonmetals (phosphorus and hydrogen) which typically form covalent bonds by sharing electrons.
