What is the Position of Hydrogen in the Periodic Table? Hydrogen is the first element of the periodic table as its atomic number is one, which means it has only one electron in its atom and thus only one electron is present in its outermost shell.

Why is hydrogen important to life?
Hydrogen is essential to our life – it fuels the sun, which converts hundreds of million tons of hydrogen into helium every second. And two hydrogen atoms are attached to one oxygen atom to make water. Both these things make our planet habitable.
What will happen without hydrogen?
Maybe volcanoes would be less common and less explosive. Also, erosion of rocks and deposition of sediments usually occurs by water. So, without hydrogen, the surface of the earth would not have water to shape it and would look very different. Think of the world with no rivers, lakes, oceans, or life.
Can you smell hydrogen?
Hydrogen is invisible and does not smell.
