Nitrogen, making up 75% of the Earth's atmosphere.
That element is Oxygen by 46.6%

Air is not an element, but made of elements. Mostly nitrogen and oxygen, with helium, hydrogen and other trace elements.
Payload weight
There is air pressure in that bag too
Moon gravity is less because the atmosphere and mass and the earths gravity is greater than the moon if you weight yourself in the earth and then you weighted yourself in the moon you would weight less in the moon you could actually float in the moon because of its atmosphere and mass
In terms of weight, iron makes up approximately 5% of the earths crust, the fourth most abundant element in the crust. However, remember Earth's Core is nearly all Iron.
oxygen is the most abundent element present i n the earth crust by weight.Because it makes covelent bond with silicon to form silicates ,which react with other minoer elements of the earth to foem a huge number of silicate minerals.
