Question

Write 1 way in which the particle of oxygen is different from the particle of hydrogen​

Answer 1

Answer:

Hydrogen and oxygen chemical elements occur in their gaseous state as diatomic molecules at the standard pressure and temperature conditions. The key difference between hydrogen and oxygen is that the hydrogen is a very light gas whereas the oxygen is a heavy gas.

Answer 2

Explanation:

This is a great question as both hydrogen and oxygen are required for humans to survive. Oxygen is necessary for us to breathe, and we also require hydrogen in the form of water. Without oxygen and hydrogen, life as we know it would never have evolved!!

Oxygen and hydrogen have different properties:

There is more hydrogen in the universe than anything else – it makes up 75% of all matter. Hydrogen gas is made of two hydrogen atoms. It is a very light gas so it easily escapes the gravity of the earth. Therefore not much hydrogen gas is found on earth – most hydrogen on earth is stuck to oxygen in the form of water.

Oxygen is the third most abundant element in the atmosphere. It makes up 50% of the earth’s mass and 90% of the world’s oceans. Oxygen is made up of two atoms of oxygen, and is most stable in a gas form.

Both oxygen and hydrogen are reactive gases and their reaction produces water which is essential for our survival.
