Question

What is the ligthest element on periodic table​

Answer 1

Answer:

Explanation:

Hydrogen  

Hydrogen is the simplest and lightest element and the most common in the entire universe. 93 per cent of all atoms in the universe are hydrogen atoms. On earth, it is relatively rare in the atmosphere – only 5 of every 100 million litres of air are hydrogen but hydrogen combined with oxygen forms all the water in the world’s oceans, lakes, and rivers.

Hydrogen is very light. The air in a room with walls 4M long and 4M high would weigh 82.5 kg, but if the same room were filled with hydrogen, it would weigh only 5.76 Kg. This is why it was used in balloons carrying human passengers. The second-ever flight, in Paris on 1st December 1783, was in a hydrogen balloon. Hydrogen was also used in giant airships until 6th May 1937, when the giant German airship Hindenburg exploded killing 36 people at Lakehurst, New Jersey, USA. Today, hydrogen fuel cars are used to power clean-energy cars.
