The 2nd most abundant in the earth's crust and has 14 neutrons is silicon In 1824 Silicon was discovered by a Swedish chemist.

Oxygen is the most abundant element in the earth's crust and is not in the boron family. Aluminum is in the boron family and is the third most abundant element in the earth's crust. Refer to the related link for a list of the 10 most abundant elements in the earth's crust and their percentages.
Oxygen is the most abundant element in Earth's crust, making up about 47% of its mass. Silicon is the second most abundant element, comprising approximately 28% of the crust's mass.
Aluminum is the Earths most abundant metal and its located in the Earths outer crust.One of the properties of crust is that it consists of a variety of sedimentary,metamorphic and igneous rocks.
Oxygen is the most common and abundant element in the Earth's crust having 47% of the mass.

That element is Oxygen by 46.6%
The second most abundant element in the Earth's crust is silicon, comprising 27.8% of the crust by mass.
The fifth most abundant element in the Earth's crust is potassium. It makes up about 2.6% of the Earth's crust by weight.
