The bond angle in a water molecule is approximately 104.5 degrees due to the bent shape caused by lone pairs on oxygen.

The bond angle in water is approximately 104.5 degrees due to the bent shape of the molecule.

The bond angle in water is approximately 104.5° due to the repulsion between the lone pairs on the oxygen atom.

The main method of hydrogen production in the industry is steam reforming of natural gas.

In the laboratory, hydrogen is commonly produced by the reaction of metals (like zinc) with acids.

When hydrogen reacts with oxygen, the main product formed is water (H2O).

When hydrogen reacts with oxygen, the main product formed is water (H2O).

The primary product of the reaction between hydrogen and chlorine is hydrogen chloride (HCl).

Deuterium is the isotope of hydrogen with one neutron, also referred to as Hydrogen-2.

Deuterium is known as heavy hydrogen because it has one neutron in addition to the single proton.

In sodium hydride (NaH), hydrogen has an oxidation state of -1.

Hydrogen chloride (HCl) is a hydrogen halide, which is a binary compound of hydrogen and a halogen.

Hydrochloric acid (HCl) is a strong acid that contains hydrogen.

Hydrogen can be produced through various methods including electrolysis of water, steam reforming of natural gas, and thermochemical water splitting.

Hydrogen is the most abundant element in the universe, making up about 75% of its elemental mass.

Protium, which has no neutrons, is the most abundant isotope of hydrogen, making up about 99.98% of hydrogen found in nature.

Hydrogenation refers to the addition of hydrogen (H2) to unsaturated hydrocarbons, such as the addition to ethene to form ethane.

Hydrogen is a non-metal at room temperature and does not exhibit metallic properties.
