Most naturally ocurring elements are a mixture of different isotopes. Look up boron for more details; I didn't look it up, but I can imagine that it consists of a mixture of isotopes that have an Atomic Mass of 10 and 11; or perhaps some other isotopes too.
Different isotopes of an element have the same number of protons, but a different number of neutrons.
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.
Boron is considered to be a relatively rare element on Earth, with an abundance of about 0.001% in the Earth's crust. However, it is found in various minerals and compounds, and is an essential nutrient for plants.
The element that is a member of the boron family and the most abundant in Earth's crust is aluminum. It makes up about 8% of the Earth's crust and is commonly used in various industries due to its lightweight and corrosion-resistant properties.
Boron makes up about 0.001% of the Earth's crust.
The most common element in group 13 (Boron group) is aluminum. Aluminum is widely used due to its abundance in the Earth's crust, as well as its properties that make it suitable for various industrial applications.

The relative abundance of boron in the Earth's crust is approximately 10 parts per million (ppm). Boron is considered a rare element in the Earth's crust, making up only a small fraction of the overall composition.
its the percentage in mass !
Aluminum :D
The boron family member is boron (B). The most abundant metal in Earth's crust is aluminum (Al).
Aluminium
Aluminium.

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.

The percent abundance of boron is approximately 19.78% for ^10B and 80.22% for ^11B.
