What is the abundance of boron in the earth's crust?
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.
What is the atomic number of baron?
The atomic number of Boron is 5.
How do you get the average amount of a mass of boron?
i know that it quite difficult to understand . you times the mass number of each element you want to find for example say the mass number for sulphur was 17 and the mass number for boron was 27 you time them both together then divide by 100 17x27= 459 then 459 ÷ 100 = 4.59
If The average mass of a boron atom is 10.81 what is the chance that you would randomly get one with a mass of 10.81?
Zero. There are NO boron atoms with a mass of 10.81 amu. The value of 10.81 is an average of the masses of the isotopes of boron.There are two stable isotopes of boron: boron-10 and boron-11, with masses of 10.012 amu and 11.009 amu. B-10 has a relative abundance of 19.9% and B-11 has a relative abundance of 80.1%.Do the math:10.012 x 0.199 + 11.009 x 0.801 = 10.81 amu
Is boron atomicly bigger or smaller than Oxygen?
Boron has a larger atomic radius but a smaller atomic mass.
Why is boron's atomic mass 10.82 and not 11?
Boron has two naturally occurring isotopes, boron-10 and boron-11. The atomic mass of 10.82 arises from the weighted average of the isotopic masses and their abundances in a sample of boron found in nature. Boron-10 is more abundant than boron-11, causing the average atomic mass to be closer to 10.82 than 11.
How can you explain this difference The element boron has an atomic mass of 10.81amu acoording to the periodic tablehowever no single atom of boron has a mass of exactly 10.81amu?
There are several isotopes of Boron, which have different levels of abundance. I don't know the accurate numbers, but say like 25% of Zu-isotopes are 1 amu, and 75% of Zu-isotopes is 2, it would be 1.75 amu for the Atomic mass. Relating Zu to B of course, what I mean is Boron's different isotopes appear in different abundances and have different masses. 14% of boron may be about 6.882 amu, but just think about it like the above analogy of Zu, where Zu either weighs 1 or 2, but never 1.75. By the way, to find amu for an element: (%1*Iso1)+(%2*Iso2)+[...]
An element on the periodic table has two naturally occurring isotopes one isotope has an atomic mass of about 10 amu the other isotope has an atomic mass of about 11 amu what is the name of this eleme?
The element with isotopes of approximately 10 amu and 11 amu is boron (B) on the periodic table. Its isotopes include Boron-10 and Boron-11.
What is the average atomic mass of boron?
The average atomic mass of Barium is 137.33 amu.
How is it that naturally occurring boron is 10.8 and normal boron is different?
Naturally occurring boron consists of two isotopes: boron-10 and boron-11. The average atomic weight of these isotopes is about 10.8. However, normal boron, which is primarily used in industrial applications, is often enriched to have a higher concentration of boron-10 for specific purposes, such as neutron shielding or in nuclear reactors. By enriching the boron with a higher percentage of boron-10, its properties can be tailored to meet the requirements of these specialized applications.
The average atomic mass of boron is 10.81 amu. Based on the atomic mass of B-10 and the relative abundances of the boron isotopes what is the atomic mass of B-11?
The atomic mass of boron-11 (B-11) can be calculated by setting up an equation based on the given average atomic mass of boron and the known atomic mass and abundance of boron-10 (B-10). Since the average atomic mass is a weighted average of the isotopes, the equation would be: (mass of B-10 * % abundance of B-10) + (mass of B-11 * % abundance of B-11) = average atomic mass of boron. Solving this equation will give you the atomic mass of B-11.
How many isotopes are in boron?

Which element has 2 istotopes with one 10 amu and the other 11 amu?
Boron is the element that has two isotopes with atomic masses of approximately 10 amu and 11 amu. The most common isotope of Boron is Boron-11, which has an atomic mass of 11 amu, while the less common isotope Boron-10 has an atomic mass of 10 amu.
Why scandium and boron in different groups?
They have different atomic numbers.
How many isotopes does boron have?
Two stable ones, 10 & 11. Several unstable.
How may protons neutrons and electrons does Boron have?
There are two isotopes of boron: boron-10 and boron-11 Both have 5 protons and 5 electrons per atomBoron-10 has 5 neutrons and boron-11 has 6 neutronsOverall this gives an atomic weight of 10.8 gmol-1
