What is the atomic number of Helium according to the modern periodic table?

Correct option is C

The correct answer is (c) 2.
· Element Category: Helium is a noble gas, which is inert and colorless.
· Significance: It's the second lightest and second most abundant element in the observable universe, primarily formed from the nuclear fusion of hydrogen in stars.
· Uses: Helium is used in cryogenics, particularly in the cooling of superconducting magnets, with the main commercial application being in MRI scanners. Its inert properties make it a safe gas for use in controlled environments.
· Discovery: Helium was first discovered in the solar spectrum during an eclipse in 1868 before it was found on Earth.
