Only 1, 3 & 4
Notes:
Scientists from the Indian Space Research Organisation (ISRO) have mapped out the global distribution of sodium on the Moon’s surface.
They used the CLASS instrument (Chandrayaan-2 large area soft X-ray spectrometer) carried by the second Indian Moon mission, Chandrayaan-2.
Sodium can be used as a tracer of the volatile history of the moon. · When compared to Earth, the moon is significantly depleted of volatile elements such as sodium.
The most abundant element found on the Moon is oxygen (about nearly 42%) among others. Iron, Silicon, Magnesium, Calcium, Titanium, etc are the elements found on the surface of the Moon.
