2.8%
not i mean 4.9%
Neodymium is relatively abundant in the Earth's crust, with an average concentration of about 38 parts per million. It is considered a relatively common rare-earth element compared to others in the lanthanide series.
The eight most common elements in the earths continental crust are; 1. Oxygen. 2. Silicon. 3. Aluminium. 4. Iron. 5. Calsium. 6. Sodium. 7. Potassium. 8. Magnesium.
Lithium is the 25th most abundant element in Earth's crust, with an average concentration of about 20 parts per million (ppm). This makes it relatively rare compared to other elements like silicon and oxygen.
Earth's crust, called the lithosphere, is made of 46.6 % oxygen, 27.7% silicon, 8.1% aluminum, 5.0% iron, 3.6% calcium, 2.8% sodium, 2.6% potassium, 2.0% magnesium, and other elements that are equal to 1.6%
crust
blah
90 persent and lava
its the percentage in mass !

Sodium is found in the Earths crust!! But i don't know about the ocean!! And Sodium is salt!!
In the universe, the most abundance metal is iron, then magnesium is next (about 1/2 as much as iron).In the earth's crust, aluminum is highest, followed closely by iron, then calcium, sodium, magnesium, and potassium.
Oxygen Silicon Sodium Potassium Magnesium Iron
Actually its neither, sodium is formed by pressure from the earths crust that creates sedimentary particles, the particles then are made into sodium by "affliction". It is also a basic element. See attached link.
The Earths crust is approximately 650 km deep.
The eight most common elements in the earths continental crust are; 1. Oxygen. 2. Silicon. 3. Aluminium. 4. Iron. 5. Calsium. 6. Sodium. 7. Potassium. 8. Magnesium.
Approximately 100 free elements are found in the earth's crust. There are eight elements that are found in somewhat of an abundance. These include: oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium.
Lithium is the 25th most abundant element in Earth's crust, with an average concentration of about 20 parts per million (ppm). This makes it relatively rare compared to other elements like silicon and oxygen.
