Question

so many hydrogen atoms​

Answer 1

Answer:

Hii

Explanation:

As you can see from its molecular formula, there are two Hydrogen atoms in a molecule of Hydrogen. In one mole of Hydrogen gas,there would be6. 02×10^23molecules. In every molecule, there are two atoms, so the number of atoms in 1 mol of hydrogen would be (6.02×10^23)×2=12.04×10^23 atoms.

Answer 2

Answer:

1. Isotopes of Hydrogen

• There are three isotopes of the element hydrogen: hydrogen, deuterium, and tritium. How do we distinguish between them? They each have one single proton (Z = 1), but differ in the number of their neutrons. Hydrogen has no neutron, deuterium has one, and tritium has two neutrons.

• The atoms of deuterium (atomic symbol: D or 2H) contain one proton, one electron, and one neutron, while those of tritium (atomic symbol: T or 3H) contain one proton, one electron, and two neutrons. Whereas protium and deuterium are stable, tritium is not: it is radioactive.

• Hydrogen is a colorless, odorless, nonmetallic, tasteless, highly flammable diatomic gas with the molecular formula H2. With an atomic weight of 1. 00794, hydrogen is the lightest element.
• Hydrogen is easily the most abundant element in the universe. It is found in the sun and most of the stars, and the planet Jupiter is composed mostly of hydrogen. On Earth, hydrogen is found in the greatest quantities as water.
