Silicon is the second most abundant element in Earth's crust and is the principal component of sand and quartz. It is widely used in various applications including solar cells, computer chips, caulking materials, and abrasives due to its semiconductor properties and abundance.
oxygen
The most abundant element in Earth's crust is oxygen, making up about 46% of its mass. Silicon is the second most abundant element, comprising about 28% of the Earth's crust.
Oxygen is the second most abundant element by volume in both the Earth's crust (after silicon) and in the Earth's atmosphere (after nitrogen).
The most abundant element in Earth's atmosphere is nitrogen, making up about 78% of the air we breathe. Oxygen is the second most abundant element in the air, at around 21%.

The second most abundant element in the universe is helium. It makes up about 24% of the elemental mass of the universe, following hydrogen which is the most abundant element. Helium is mostly found in stars and plays a crucial role in nuclear fusion reactions.
Hydrogen is the most abundant element in the known Universe; helium is second.
no
The second most abundant element in the Earth's crust is silicon, comprising 27.8% of the crust by mass.
Silicon is the second most abundant element in Earth's crust after oxygen. It is a major component of rocks, minerals, and soils.
Hydrogen is the most abundant element in the known Universe; helium is second.
Helium!
Silicon.
oxygen
The most abundant element in the Earth's crust is oxygen at 46%. The second is silicon at 28%.
Most of our body is made up of water (H20); therefore hydrogen is the most abundant (i.e. numerous) element and oxygen is the second most abundant. However, since oxygen is much heavier than hydrogen, it comprises a larger percentage of body weight (about 65%) than does hydrogen (about 10%).
