Usually, the weight of an atom would be about twice that of the atomic number. For example, Boron's atomic number is 5, and it has an Atomic Mass 0f 10.81 amu. This is because of the fact that a neutron and a proton both weight about 1 amu, and an electron is insignificant. To calculate the atomic weight to a higher accuracy than a mere estimate, is beyond me. I hope this helped.

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.

What is the atomic mass of boron?
The atomic mass of boron is approximately 10.81 atomic mass units.
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
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.
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 do you calculate the number of neutrons in boron?
To calculate the number of neutrons in boron, subtract the atomic number from the atomic mass. The atomic number of boron is 5, and the atomic mass is around 10.81. Therefore, boron has approximately 6 neutrons (10.81 - 5 = 5.81).
What is the average atomic mass of boron?
The average atomic mass of Barium is 137.33 amu.
The element boron has only two stable isotopes one stable isotope has a mass number of 10 and the other has a number of 11. what could be the atomic weight of the element?
From what I remember of chemistry, the amu of each element on the periodic chart is a weighted average of all the isotopes of that element. So, as you indicated - 80.2% of Boron exists as B-11 and 19.8% of boron exists as some other isotope. In that case you can get an estimate of the amu of the unknown through simple math: 0.802*(11.01 amu) + 0.198*(X amu) = 10.81 Solving for x, you get 10.00 amu
What are the atomic numbers of boron?
The atomic number of boron is 5.
What is the atomic symbol for boron?
The Atomic Symbol is B
How do you calculate the abundance of boron isotopes?
To calculate the abundance of boron isotopes, you would typically need to know the masses and natural abundances of each isotope. You can then use these values to calculate a weighted average, taking into account the abundance of each isotope relative to its mass. The formula for calculating isotopic abundance involves multiplying the natural abundance of each isotope by its mass and then summing these values for all isotopes.
