It's the first element in the Periodic Table. Hydrogen is colorless and odorless in normal conditions. Hydrogen is diatomic, meaning it is most often found as H2(Other elements that are diatomic are Oxygen, Fluorine, Bromine, Iodine, Nitrogen and Chlorine, Or HOFBrINCl, respectively) . The hydrogen atom is formed by a nucleus with one unit of positive charge, a proton, and one of an electric charge, an electron. The atomic number of hydrogen is 1 and its atomic weight is approximately 1.00797 g/mol. It is one of the main compounds of water. It's widely spread throughout Earth's atmosphere, yet it is only considered to be 0.000055% of gases in the atmosphere. It has three hydrogen isotopes: Protium, containing 0 neutrons in the neucleus, found in more than 99.985% of the natural element; Deuterium, containing both a proton and a neutron in the neucleus, found in nature in 0.015% approximately; and Tritium, containing one proton and two neutrons in the nucleus, which appears in small quantities in nature. It can be artificially produced by various nuclear reactions. Hydrogen is the main cause of one of the strongest bonds: Hydrogen bonds, present in Hydrogen Fluoride, Water (H2O) and Ammonia (NH3). As well, Hydrogen's chemical properties lead to its extremely low point of vaporization and currently unknown definite point of solidification.
Hydrogen gas is a colorless, odorless, and tasteless gas at room temperature. It is highly flammable and burns with a clean, blue flame. Hydrogen is the lightest element, and it has the lowest density of any gas.

what is the chemical formula for zinc chloride and hydrogen gas?
The chemical formula for zinc chloride is ZnCl2, and for hydrogen gas, it is H2.
Is hydrogen burns in chlorine gas chemical or physical change?
When you combust hydrogen in air, the hydrogen will combine with oxygen to form water. Therefore, the hydrogen and oxygen are undergoing a chemical change to become bonded together producing H2O: 2H2 + O2 → 2H2O + Heat
What are hydrogen chlorine and sodium examples of?
Hydrogen, chlorine, and sodium are examples of chemical elements. Each element is a unique type of atom that has specific properties and characteristics. Hydrogen is a colorless, odorless gas, chlorine is a greenish-yellow gas, and sodium is a soft, silvery metal.
What is the chemical symbol for hydrogen gas?
The letter H is the chemical symbol for the element hydrogen.
When sodium metal in water produces hydrogen gas is it a physical property or a chemical property?
The reaction of sodium metal with water to produce hydrogen gas is a chemical property. This is because a new substance (hydrogen gas) is formed as a result of a chemical reaction between sodium and water.
What chemical properties do the products of electrolysis have that are produced by the decomposition of water?
The chemical properties of the products of electrolysis of water include hydrogen gas and oxygen gas. Hydrogen gas is flammable and can form explosive mixtures with air, while oxygen gas supports combustion. Both gases are diatomic molecules at room temperature and pressure.
When zinc reacts with acids producing hydrogen gas is it a chemical or physical change?
When zinc reacts with acids to produce hydrogen gas, it is a chemical change because new substances are formed (zinc salts and hydrogen gas) with different properties from the original substances.
What is the chemical of hydrogen gas?
The chemical formula for Hydrogen gas is H2
What is the chemical formula of hydrogen gas?
The chemical formula for Hydrogen gas is H2
When hydrogen burns in chlorine gas it is a physical or chemical change?
When hydrogen burns in chlorine gas, it undergoes a chemical change. This is because new substances are formed as a result of the reaction, such as hydrogen chloride. The properties of the starting materials are different from those of the products.
When hydrogen peroxide is poured on a cut on a persons skin the hydrogen peroxide breaks down into water and oxygen gas what type of change is this?
This is a chemical change because the hydrogen peroxide molecules are broken down into different substances (water and oxygen gas) with new chemical properties.
Are the physical and chemical properties of HCl different from those of H2 and Cl2?
Yes, HCl is a compound formed by the reaction of hydrogen and chlorine, so it has different properties from its constituent elements H2 (hydrogen gas) and Cl2 (chlorine gas). HCl is a polar molecule with acidic properties, while H2 and Cl2 are nonpolar molecules with different reactivity and chemical characteristics.
Is hydrogen a gas or chemical?
Hydrogen is a gas. Of course, it's also a chemical. It's part of chemistry.
What describes chemical properties?
It reacts with hydrogen
Nitrogen gas react with hydrogen gas to form ammonia what are the reactants in this chemical reaction?
nitrogen gas and hydrogen gas
When you run an electrical current through liquid water the water molecules are split apart to form oxygen and hydrogen gas this changed what properties of the water?
The splitting of water into oxygen and hydrogen gas changes its chemical composition but does not change its physical properties. The resulting oxygen and hydrogen gases can be collected separately but the water will still retain its characteristic properties such as boiling point, freezing point, and density.
what is the chemical formula for zinc chloride and hydrogen gas?
The chemical formula for zinc chloride is ZnCl2, and for hydrogen gas, it is H2.
