Which is considered as first molecule of our universe

Chemistry, Universe 0

A. Hydrogen
B. Helium Hydride ion
C. Iron
D. Ozone

Answer & Solution

Option: B
Explanation :Which is considered as first molecule of our universe? The correct Answer is Helium Hydride ion. Helium Hydride ion is considered as first time molecule of our universe because it has been detected in space after decades of searching. Moreover Scientists discovered its signature in our own galaxy using the world’s largest airborne observatory, NASA’s Stratospheric Observatory for Infrared Astronomy, or SOFIA, as the aircraft flew high above the Earth’s surface and pointed its sensitive instruments out into the cosmos.

When our Universe was young then only a few kinds of atoms existed. Astrophysicists believe that around 100,000 years after Big Bang so ionized hydrogen and neutral helium atoms combined to make the helium hydride ion (HeH+) first time. This molecule should be present in some parts of the modern Universe but it has never been detected in space until now.
Hence today our Universe is filled with large complex structures like planets, stars and galaxies. At this time Universe was hot and only few types of atoms, mostly helium and hydrogen exists.
