What is hydrogen's properties?

Hydrogen is a colorless, odorless, tasteless, and nonpoisonous gas under normal conditions on Earth. It typically exists as a diatomic molecule, meaning each molecule has two atoms of hydrogen; this is why pure hydrogen is commonly expressed as “H₂“.

What are 5 hydrogen properties?

Hydrogen has a melting point of -259.14 °C and a boiling point of -252.87 °C. Hydrogen has a density of 0.08988 g/L, making it less dense than air. It has two distinct oxidation states, (+1, -1), which make it able to act as both an oxidizing and a reducing agent.

What are the properties and uses of hydrogen?

Hydrogen also has many other uses. In the chemical industry it is used to make ammonia for agricultural fertiliser (the Haber process) and cyclohexane and methanol, which are intermediates in the production of plastics and pharmaceuticals. It is also used to remove sulfur from fuels during the oil-refining process.

What is hydrogen's density?

Gaseous hydrogen, with a density of 0.00523 lb/ft3, has a specific gravity of 0.0696 and is thus approximately 7% the density of air. For liquids, water (with a density of 62.4 lb/ft3; 1000 kg/m3) is used as the reference substance, so has a specific gravity of 1.0 relative to itself.

What is an element's properties?

All elements have properties. Those properties include, but are not limited to, conductivity, magnetism, melting point, boiling point, color, state of matter, and others. Elements with similar properties are grouped together in different areas of the periodic table of elements.

What exactly is hydrogen?

Hydrogen is a chemical element. It has the symbol H and atomic number 1. It has a standard atomic weight of 1.008, meaning it is the lightest element in the periodic table. Hydrogen is the most common chemical element in the Universe, making up 75% of all normal (baryonic) matter (by mass).

What is the property of oxygen?

Oxygen is a colorless, odorless, tasteless gas. It changes from a gas to a liquid at a temperature of -182.96°C (-297.33°F). The liquid formed has a slightly bluish color to it. Liquid oxygen can then be solidified or frozen at a temperature of -218.4°C (-361.2°F).

What happens if you breathe hydrogen gas?

Inhaled hydrogen gas (H2) has been shown to have significant protective effects on ischemic organs. Clinical trials abroad have shown promise that treatment of patients suffering from stroke, cardiac arrest, or heart attacks may benefit from inhaling hydrogen gas during the early recovery period.

What are the 3 defining characteristics of an element?

These properties include color, density, melting point, boiling point, and thermal and electrical conductivity. While some of these properties are due chiefly to the electronic structure of the element, others are more closely related to properties of the nucleus, e.g., mass number.

What are the 3 major properties of elements in the periodic table?

Atomic properties that are critical to the behavior of elements are electron configuration, atomic size, ionization energy, electron affinity, and electronegativity. The electron configuration (nl^#: spdf notation) gives the distribution of electrons in principal energy levels and sublevels of an atom.
